SynCom Network, Inc SM-B1

Chapter 1 System Introduction & Applications

1.1 System IntroductionsThe SM-B1series is part of the SynCom SDH SM series products. The name of the SM stands forSDH Multiplexer, whereas “-B1” means the Box type that supports high-speed interface, STM-1.The basic type, SM-B1 is a SDH multiplexer equipped with two STM-1 optical aggregate interfacesand 8/16/21/42/63 2.048 Mbit/s tributary interfaces (It is also referred to as 2Mbit/s, 2M, or E1interchangeably throughout this or other relevant documents.). An enhanced version, SM-B1 Plus,provides more choices: (1) to increase the number of E1 tributary interfaces up to 63; or (2) toprovide T1 tributary interfaces as well as E1 interfaces. Note that internally each T1 signal isembedded in an E1 signal. The hierarchical structure employed in SM-B1 series for multiplexing E1tributary into STM-1 is compliant with ITU-T G.707 as shown in the figure below.

Container (C) Tributary Unit Group (TUG)

Virtual Container (VC) Administrative (AU)

Tributary Unit (TU) Administrative Unit Group (AUG)

Figure1-1 Multiplexing Structure

As shown in the picture below, the SM-B1 enclosure is a stand-alone entity with two front accessoptical interfaces. Interfaces to low speed signals, office power, and operation interfaces can beaccessed from the back. This design is so that the SM-B1 system is constructed in a compact form.The mechanical structure is so compact that it can be used as a desktop unit. It can be easily fit into acabinet without taking much space. It can also be mounted in a standard 19-inch wide rack. The SM-B1series can be field programmed as a standard SDH Terminal Multiplexer (TM), a LinearAdd/Drop Multiplexer (LADM), or an Optical Regenerator (OR) using the same unit.

The SM-B1series provides the following management functions: fault management, performancemanagement, configuration management, and security management. It also supports centralizednetwork management. With SynCom Element Manager; multiple SM series subnetworks can bemanaged from a central office.

The SM-B1 series supports a complete operations interface that is consistent with theTelecommunication Management Network (TMN) concept (ITU-T Recommendation M.3010) andthe requirements of the SDH Management (ITU-T Rec. G.784). Being one of the SynCom SDHseries products, the SM-B1 series works seamlessly with other SynCom SDH SM series products:SM-M1, SM-M4, SM-B16, and the SynCom Element Manager: EM, etc.

In the subsequent clauses, "SM-B1" is used for both SM-B1 and SM-B1 Plus models. Only whenfeatures for a specific model are unavailable in the other, the specific model will be mentioned.

1.3 Role TypeEach SM-B1 has a defined role in an SDH system application. Two roles are defined in currentapplications:

Central Office Terminal (COT); and

Remote Terminal (RT).

The role type is field programmable. The COT is similar to the Gateway Network Element (GNE)defined in ITU-T Rec. G.784. It acts as the gateway between the Network Elements (NEs) in thesubnetwork and the EM/GUI. The significance of the role type is that certain commands are allowedat the COT only. The details are described in CHAPTER 3 “Operation, Administration &Provisioning (OAM&P)”.

1.4 System Modes and Clock SourceThe SM-B1 can be field programmed into the following modes to support various applications. Theselectable system modes are as the following:

Terminal Multiplexer (TM) mode;

Linear Add/Drop Multiplexer (LADM) mode;

Two (independent) Terminal Multiplexers (2xTM) mode; and

Multiplexer Section Protection (MSP) mode.

The first two modes listed above are standard SDH STM-1 mode. When an SM-B1 is programmed as

4


a TM, only one STM-1 will be active (working STM-1 is user configurable). When an SM-B1 isprogrammed as a 2xTM, it acts as if it houses two back-to-back TMs in one enclosure. The two TMsshare the same internal (free-run) clock source.

1.4.1 Terminal Multiplexer (TM) Mode ApplicationThe SM-B1 may be deployed as a Terminal Multiplexer. It supports a point-to-point application if itis connected with another TM that could be an SM-M1 or an SM-B1.

The SM-B1 may be deployed as a TM when it is an end node in either a point-to-point or a chainconfiguration as Figure 1-2. When it is assigned as a TM, user can select West or East STM-1 to beactive.

SM-B1 provides many clock timing sources for network synchronization. They are: east optical linetiming, west optical line timing, external clock input timing (2.048Mbps or 2.048MHz), tributaryE1/T1/E3/T3 (optional) timing, and internal timing. The internal timing comes from an oscillatorwith ±4.6ppm accuracy. The user can set the priority and the sequence of timing sources for clockswitching in case the current source does not work. The switching is done automatically by system. Ifall the clock sources fail, SM-B1 will go into holdover mode with stable clock for 24 hours at least.

Figure1-2 SM-B1 as TM

1.4.2 Linear Add/Drop Multiplexer (LADM) ApplicationThe SM-B1 may be configured as a Linear Add/Drop Multiplexer (LADM). The SM-B1 provides aflexible, cost-effective solution for access network. The LADM SM-B1 is ideally suited for low-density routes that primarily transport 2Mbit/s traffic.

The clock source of a LADM SM-B1 is automatically assigned by the system and is generated fromTGU. TGU is optional and if TGU is absent, only through mode timing can be selected for LADMapplication. The SM-B1 is assigned as LADM as an intermediate node in a chain, a ring as Figure 1-3.

Figure1-3 SM-B1 as LADM

1.4.3 Multiplexer Section Protection (MSP) mode ApplicationThe SM-B1 may be configured as MSP when the system application is the point-to-point ringtopology. Both two nodes should be set as MSP mode.

As SM-B1 is configured as MSP mode, the low speed interface will always switch follow the high-speed interface.

In each applications described below, the SynCom SDH products: SM-B1 and SM-M1; forms asubnetwork. Each subnetwork shall contain one COT and one or multiple RTs.

1.5.1 Point to Point Ring ApplicationTwo SM-B1's may be connected to provide a point-to-point configuration. To take advantage of thePath Protection capability of the SM-B1, the configuration may be considered as a two-points ring asFigure 1-4 below. In such case, one of the nodes shall be configured as a 2xTM in the COT role; theother shall be configured as a LADM in a RT role. Either SM-B1 in Figure 1-5 may be replaced bySM-M1.

Figure1-4 Point-to-point ring application

1.5.2 Chain ApplicationThe SM-B1 may be connected in a series to form a chain. In such case, one end, say, the beginningend shall be configured as a TM. All the intermediate nodes shall be configured as LADM. The lastone on the chain shall be configured as a TM.

1.5.3 Two Joint Chains ApplicationIn Figure 1-5, two chains are jointed at the COT node. In this application, the COT shall be assignedas 2xTM. In Figure 1-5, an SM-M1 is the COT. An SM-B1 can also play the COT role. The decisionto use either SM-M1 or SM-B1 depends on the number of channels required and/or future expansion.The COT mode shall be assigned as 2xTM. Each intermediate SM-B1 shall be assigned as LADM inthe RT role. The two end nodes shall both be assigned to the TM mode while playing the RT role.

Chapter 3 Operation, Administration & Provisioning (OAM&P)

3.1 OverviewThe SM-B1 is a standard SDH system that provides optical transport. This system is designed foreasy installation and operation. Centralized operation is supported by a full set of single-endedcontrol and maintenance features. Automatic diagnostics tests and default provisioning simplify theinstallation. A Graphical User Interface provides access to sophisticated maintenance and reportingfeatures. In summary, the SM-B1 provides excellent facilities for Operations, Administration,Maintenance, and Provisioning. They are described in detail in this chapter.

3.2 Operations InterfacesThe SM-B1 provides various interfaces that support user’s access to the system and allow thealarm/status information generated by the system to be reported.

Local operation interfaces include friendly Graphical User Interface (GUI), transmission statusindicators, E1/T1 status indicators, office alarms, and orderwire interface.

Remote control of all the Network Element (NE) is generally via the SM-B1 located at the CentralOffice, called Central Office Terminal (COT). The COT is directly connected to the OperationsSupport System (OSS) or Element Manager (EM). To support remote operations, the COT isconnected to remote SM-B1, called Remote Terminals (RT), via the Data Communication Channel(DCC) that is embedded in the SDH signal. The COT performs the function of a Gateway NetworkElement (GNE).

The following sections will describe all the above operations interfaces in detail.

3.2.1 Graphical User Interface (GUI)The SM-B1 provides a DB-9/RJ45 connector to support the Graphical User Interface (GUI). TheGUI requires a Window 95 or higher based PC connects to this interface. With the software packagethat is a Microsoft C++ based management software, the user can manage the local system and theother SynCom SDH series products that are connected in the same subnetwork.

Figure3-1 Add comport Window

Figure3-2 Add LAN port Window

All operation functions supported by EM GUI include maintenance, administration, provisioning themultiplexer, time slot assignment, and displaying the provisioning information and equipmentinformation.

3.2.2 DCC InterfaceThe SM-B1 has the capability to use Section DCC (D1~D3) for communications with other NEs inthe same SDH subnetwork.

12


At this NE/NE interface, the SM-B1 currently supports the lower three layers of the OSI 7-layerinterface: the DCC, LAPD, and CLNP. The application layer messages are Object-Oriented and areconsistent with the GDMO models defined in ITU-T Rec. G.774. This interface is upgradeable bysoftware changes to migrate to Common Management Information Service Element / AbstractSyntax Notation 1 (CMISE/ASN.1).

3.2.3 Push-Button, Transmission Status and E1 Status IndicatorsThe SM-B1 provides a RESET push-button on the front panel to request the system for soft boot, andalso an ACO (Alarm Cut-Off) push-button to cut off audible alarm immediately.

The SM-B1 also provides the transmission status indicators to show the system-level information.Three LEDs on the front panel are for this purpose. They are: (1) System work or fail(WORK/FAIL); (2) Major /Minor Alarm (MAJOR/MINOR); (3) East STM-1 status (EAST STM1);(4) West STM-1 status (WEST STM1); and (5) Alarm Cut-Off (ACO).

In addition, the SM-B1 provides 4/8/16/21 LEDs and SM-B1 Plus provides E1/T1 LEDs orE1/E3/T3 LEDs to indicate the status of channels.

The above buttons and indicators perform the tasks independent of the EM GUI or any external testequipment.

3.2.4 Office Alarms The SM-B1 provides four office alarms: audible major alarm (MJA), visual major alarm (MJV),audible minor alarm (MNA), and visual minor alarm (MNV). These signals also can be wired to theexternal alarms equipment. User could make a decision with the Major/Minor alarms’ classificationsassociated of equipment or signal failure.

To prevent intermittent failures from causing unnecessary maintenance activities, a provisionablealarm hold-off delay with default value of 2 seconds is provided. An office alarm will not beactivated, unless the duration of the condition is greater than the alarm hold-off delay. When a failureis cleared, an alarm clear delay with default value of 5 seconds prevents premature clearing of thealarm. As with the system indicators, when multiple alarms are active, the highest-level office alarm(audible and visual) is activated. When the highest-level alarm is cleared, the office alarm “bumpsdown” to the next highest-level active alarm.

The audible office alarms could be silenced through activation of the ACO button. However, visualalarms can’t be extinguished by the ACO function. If another alarm occurs while the ACO is active,the highest-level audible alarm is activated even if the new alarm has a lower-level condition.

3.2.5 Discrete Environmental-Alarms In here, 8 couplers are used to monitor 8 environmental conditions. User may choose 4 out of 14definable alarms to monitor environmental conditions. The optical couplers are set to open when thecondition is normal and closed when alarm occurred.

Figure3-3 Environmental-alarms & Office-alarms

13


3.2.6 Equipment error performance The SM-B1 provide with virtually error-free (less than 1 error in 1012 bits) transmission of digitalsignal through the system from El interfaces to the looped-back STM-1 optical aggregate interfaceback to the El interfaces.

3.2.7 Orderwire Voice Interface (Optional)The SM-B1 provides orderwire (OW) voice interface carried in bytes E1 and E2 in the transportoverhead.

User can use the OW channels to communicate between remote NEs in the network, or duringcoordinated maintenance activities such as provisioning and testing of new services.

3.3 AdministrationAdministration can be divided into System Administration (including housekeeping and security) andMemory Administration (including memory backup and restoration, data manipulation).

3.3.1 System AdministrationSystem administration deals with functions needed for proper operations of the SM-B1 in atelecommunication network. System administration functions include:

Housekeeping

Security

In-Service and Out-Service

3.3.1.1 HousekeepingThe housekeeping of the SM-B1 is as follows:

Set date and time

3.3.1.2 Administrative states Administrative states can be separated to two: in-service and out-of-service. They're userconfigurable. If the interface is set to in-service state, it means this interface is used and running.Alarms and performances for the interface must be collected and monitored. If interface is set to out-of-service state, it means this interface is dead. That is, alarms are not collected and performances are

14


not monitored. This might happen if interface is under maintenance. For avoiding mistake, test modecan be set for interface if it’s in out-of-service state.

3.3.1.3 Operation statesOperation states show the current situation for the interface. If Administrative state is in in-servicestate, then operation states might in "UP" or "DOWN" state. UP state means the interface runscorrectly and DOWN state means no TSA is assigned for E1 interface or not used for opticalinterface in TMx1 mode. And if administrative state is in out-of-service state, then operation statesmight in "DOWN" or "TEST" state. TEST state means the interface is doing some test function, e.g.,loopback test.

Figure3-4 Administrate & Operation State window

3.3.2 Memory AdministrationMemory administration deals with the functions needed to control and administrate the SM-B1database. Memory administration includes:

Memory backup and restoration

The data manipulation

3.3.2.1 Memory Backup and RestorationThe SM-B1 provides a local primary non-volatile memory backup on the MPU circuit packRestoration of data from the local backup memory, once initiated, will be completed within 1 minute.

3.3.2.2 Data ManipulationTo provide new services and equipment in the network, the SM-B1 has the capability of datamanipulation to deal with editing and retrieving data in the database including all settings andnetwork element configurations.

3.4 MaintenanceMaintenance is responsible for maintaining the proper functions of the NEs and the network.Maintenance includes alarm surveillance; performance monitoring, testing capability, control featuresand optical interface protection switching that are essential to the normal operations of the NEs.

The EM GUI together with the SM-B1 network management capabilities makes it easy for the user toperform the following maintenance tasks:

The trouble detection: include LOS, LOF, LOP, LOM, SD(Signal Degraded) equipment failures,loss of synchronization, troubles on the Automatic Protection Switch (APS) channel.

15


The trouble or repair verification: verify the continued existence or nonexistence of a problembefore beginning or closing out work on that problem.

The trouble sectionalization: sectionalize the failure to one of the terminating NEs or the facilitythat connects them. This process is achieved through analyzing alarms, maintenance signals (e.g.,AIS), and PM data; testing access; and activating loopbacks.

The trouble isolation: test access, loopbacks, performance data, and diagnostics available withinthe NEs are used to isolate the failures down to a replaceable circuit pack, module, or a fiber.

Restoration: by use of protection switching and traffic rerouting to allow services to be restoredeven though the failure may not have been repaired.

3.4.1 Alarm SurveillanceAlarm surveillance deals with the detection and reporting of certain occurrences in the network.

3.4.1.1 Failure StatesThe SM-B1 can detect certain failure states relevant to the layers of functionality it provides.

(1) Incoming STM-1 signals are monitored for LOS and LOF, LOP;

(2) Incoming 2 M signals are monitored for LOS;

(3) Equipment failures

User can set the severity attributes, and retrieve this information.

Figure3-5 STM-1 Severity Attribute Setting Window

Figure3-6 E1 Severity Attribute setting Window

3.4.1.2 AIS: Alarm Indication SignalingAIS is used in the digital network to alert downstream equipment that an upstream failure has beendetected. The SM-B1 generates and detects the following alarm indication signals (AISs):

MS (Multiplex Section) AIS

AU4 (Administration Unit) AIS

TU12 (Tributary Unit) AIS

16


3.4.1.3 FERF: Far End Receive FailureFERF signals have been used in the digital network to alert upstream terminals of a downstreamreceive failure. The layered maintenance strategy incorporated in the SDH signal format expands theapplications of these signals in the network. In particular, FERF signals can be used for troublesectionalization. The SM-B1 provides FERF signals as follows:

MS FERF

VC4 (Virtual Container-4) FERF

VC12 FERF

FIGURE 3-7, FIGURE 3-8, and FIGURE 3-9 shown below illustrate the relationship of these AISand FERF maintenance signals.

18


Figure3-9 Maintenance Signals at Low Order Path (TU12) Termination Point (AsynchronousMapping for 2 Mbit/s into Floating TU12) (continued)

3.4.1.4 Fault Detection, Isolation and ReportingThe SM-B1 continuously monitors its circuit pack and all incoming signals for faults.

When a fault is detected, the SM-B1 uses automatic diagnostics to isolate the fault to a particularsignal or circuit pack. Failure states that persist for the provisionable period of time (2.5+0.5seconds) will lead to indications. The system autonomously reports all alarm and status conditionsthrough appropriate system and equipment indicators, office alarm relays, the fuse and alarms panel,the local CIT, and the remote OS.

Figure3-10 Automatic Alarms Report Windows

19


The system stores a record for all fault conditions. The user can retrieve a report of active alarm andstatus conditions via the maintenance toolbar, locally at the CIT, or remotely by the OS. The reportincludes the source address of the alarm as well as date and time of the alarm, whether or not thecondition is service affecting, and a short description of the condition.

The attributes of those alarms could be set and retrieved by software on demand locally at the EMGUI or remotely by the OS through X.25.

3.4.2 Performance Monitoring(PM)The SM-B1 provides the capability of gathering PM data to support in-service monitoring oftransmission quality. These proactive maintenance include three key steps:

Detection of transmission degradation based on regenerator section (RS), multiplex section (MS),and path;

Derivation of useful performance parameters from the detected degradation;

Communication of these parameters to a surveillance OS or local craftsperson via two distinctmechanisms:

─ Ordinary performance parameter queries made by an OS or a local craftsperson fortesting/diagnostic purpose, or to address the service quality concerns of a customer; and

─ Threshold-Cross-Alert (TCA) messages, bearing the exact performance parameter registerwhose threshold was crossed, are used to notify a surveillance OS of a degradation.

3.4.2.1 PM ParametersThe SM-B1 provides the following performance monitoring parameters:

Regenerator Section (RS) Layer PM

The SM-B1 monitors Severely Errored Framing Second (SEFS), and provides the following storageregisters:

Current 15-minute

3.4.2.2 PM Data Collection and InitializationPerformance parameters are accumulated for each monitored transport entity and each direction oftransmission. The SM-B1 provides the capability to retrieve the contents of any parameter storageregister at any time. The parameters are collected on a continuous basis, except during trouble orfailure conditions such as LOS, LOF, AIS, or LOP, the ability to accumulate such parameters is lostor severely hampered. The PM accumulation during troubles is conducted according to the followingrequirements:

Capability is provided to initialize the registers for accumulated performance automatically on 15-minute and daily time boundaries. User can initialize the registers manually at any time via the GUIor remote EM or OS.

3.4.2.3 Threshold Crossing Alerts (TCA)The SM-B1 provides threshold registers for monitored performance parameters as described insection 3.4.2.1, and the capability to retrieve the contents of any parameter storage register remotelyfrom OS or locally from COT at any time. Default values for current 15-minute and current daythreshold registers are provided in Chapter 5. These registers are provisionable remotely from OS orlocally from COT.

Figure3-11 Retrieving and Setting PM Thresholds Window (for STM1):

22


FIgure3-12 Retrieving and Setting PM Thresholds Window (for E1)

The TCA will be sent to the COT and surveillance OS by use of an autonomous message when acurrent 15-minute or current day register crosses the corresponding threshold value. A TCA messageprecisely identifies the performance parameter register whose value has exceeded its threshold, andthe corresponding threshold value. They constitute the notification mechanism associated withperformance monitoring.

TCA is classified as a transient condition. The alert will be cleared automatically on the 15-min ordaily time boundary.

3.4.3 Testing CapabilityTesting deals with procedures that result in isolation of a failure to a replaceable or repairable entity.

Testing activities includes:

Analyzing alarms, PM data, and maintenance signals

Executing diagnostics

Executing controls, such as switch to protection

Activating loopbacks

In each of these activities, operations personnel gain access through either GUI or the remote EM orOS.

Craftsperson can use the SM-B1 internal testing capabilities for installation and manualtroubleshooting. Maintenance tools that achieve this isolation, besides those built into the SDH signalformat, are diagnostics, and loopbacks.

3.4.3.1 Self Diagnostics CapabilityDiagnostics capabilities for equipment failures are provided in the SM-B1. These diagnostics occurautomatically during the circuit pack initialization or equipment turn-up before the circuit pack goesinto service, and may be run routinely or on demand.

23


3.4.4 Loopback Test CapabilityTo support pre-service operation practices and test-related activities in some applications, SM-B1provides a combination of loopback capabilities – diagnostic and line loopbacks for STM-1, and 2Mbit/s. These capabilities can be activated locally via GUI and remotely via an EM or OS. It isexplained below:

Figure3-13 Loopback test illustrations

These loopbacks connect the signals about to be transmitted to the associated incoming receiver.

When the signal is being loopbacked, it will interrupt the flow of traffic and change the normaltransmission, the associated facility and circuit pack must be set in the maintenance state (out-of-service).

3.4.5 Control FeaturesThe SM-B1 provides the following control functions from either hardware push-button or EM GUIoperations:

Retrieve equipment configuration status: Equipment configuration status, including the indicationof the active hardware entities in redundant equipment and the active synchronization source, isretrievable via the EM GUI operations.

Manual Switch the timing source: User could manual switch the timing setting of the SM-B1system via the EM GUI operation.

Furthermore, the system may be re-initialized (reset) via hardware push-button or EM GUIoperations. The ”system reset” could be categorized in 4 levels:

Reset Software by either push the RESET button or via EM GUI operation: A push-button isprovided on front panel to restart the system controller. An EM GUI operation for “Softwarereset” is also provided. System restarted by pushing the push-button has the same effects as that ofa soft boot. It will not affect the provisioned data.

Reset hardware to restart system by EM GUI operation or off/on the power: In addition to “resetCPU”, all hardware chips will be restarted. This operation will not affect the provisioned data thatis stored in the non-volatile memory. But the failure states, protection switching configuration,performance parameters, and other information necessary for fault isolation will be changed toreflect the current status.

Reset FPGA to restart system by EM GUI operation: In addition to “reset hardware”, thisoperation will download FPGA codes again.

Reset OODB to restart system by EM GUI operation: In addition to “reset hardware”, thisoperation “hard boot”, reloads the default values to the database and will affect the state ofmemory and other resources.

24


3.4.6 Optical Interface Manual SwitchUser can locally or remotely execute/release the optical interface protection switching to the SM-B1-1 by EM GUI. The protection switching priority and the K1 byte are shown as the table below:

Table3-3 The protection switching priority

The switching type K1 bytebit

1 2 3 4

Auto switch: SF 1 1 0 0

Auto switch: SD 1 0 1 0

Manual switch 1 0 0 0

3.4.7 VC12 Path Protection SwitchingPath protection switching at VC12 level; i.e. switching on per E1 basis, is available at all SynComSDH series products: SM-M1 and SM-B1. This switching mechanism is applicable at ringapplication as depicted in Figure 3-13. The traffic is going at clockwise or counter-clockwisedirection at normal situation without any defect in the ring. If an optical fiber breaks or a circuit packfailure occurs, all nodes with affected traffic will reverse the working path to recover thetransmission within 50 milli-second. This is a more economic way to achieve the network robust than1+1 line protection switch.

Figure3-14 VC12 path protection switching ring(PPSR) traffic illustration

Note: Traffic in clockwise direction is the working one and the traffic in the counter-clockwisedirection is the protection one.

3.4.7.1 How to Enable Path Protection SwitchingVC12 path protection switching mechanism can be enabled during the initiation of the time slotassignment (TSA) by choosing the cross connect (XC) method as Dual Feed as illustrated at Figure3-14. As the dual-feed XC method is selected for a VC12 path connection, the outgoing traffic willbe dual-fed to both optical lines and the termination node can choose either of optical lines to dropthe traffic from.

25


Figure3-15 E1 XC for PPSR Support

3.4.7.2 How the Path Protection Switching is MadeThe selection of a working VC12 path can be made automatically or by the user. Once the system ispowered up, system software continues monitoring all the VC12 path connections and makesprotection switching automatically if a VC12 traffic defect is detected.

A user may also manually switch the working path by selecting the drop side to East STM1 or WestSTM1.The input arguments include side selection and a switch priority. Switch priorities for manualswitch include Manual and Forced. After a manual switch with priority of Manual or Forced isinvoked, the current protection switch priority will be lift up from Auto to Manual or Forced. Theprotection switch, automatically or manually, may occur only if the switch priority is greater than thecurrent one.

3.5 ProvisioningThe SM-B1 allows the user to customize many system characteristics through its provisioningfeatures. For example, performance-monitoring thresholds can be customized for each installation viathe EM GUI operations.

3.5.1 Default ProvisioningInstallation provisioning is minimized with pre-determined default values set in the factory. Eachparameter is given a default value. The default values for software parameters are maintained inCPU. All provisioning data are stored in non-volatile memory to prevent data loss during powerfailure.

3.5.2 Local and Remote ProvisioningIn the SM-B1, many provisioning parameters are software settable to allow local or remoteprovisioning. This feature is provided especially for those parameters likely to change in service tosupport centralized operation practices.

26

PM Sync. Time: The funciton provides to set PM synchronization time.

Set PM: The function provides the user to clean all PM record.

4.5.7 Administrate & Operation StateAdministrative states can be separated to two: in-service and out-of-service. They’re userconfigurable. If the interface is set to in-service state, it means this interface is used and running.Alarms and performances for the interface must be collected and monitored. If interface is set toout-of-service state, it means this interface is dead. That is, alarms are not collected andperformances are not monitored. This might happen if interface is under maintenance. Foravoiding mistake, test mode can be set for interface if it’s in out-of-service state.

Operation states show the current situation for the interface. If administrative state is in in-servicestate, then operation states might in “UP” or “DOWN” state. UP state means the interface runscorrectly and DOWN state means no TSA is assigned for E1 interface or not used for opticalinterface in TMx1 mode. And if administrative state is in out-of-service state, then operation statesmight in “DOWN” or “TEST” state. TEST state means the interface is doing some test function,e.g., loopback test.

Chapter 5 Installation Guide

5.1 OverviewThis chapter provides the guideline to the installation procedure for a simple end-endnetworkconfiguration. Since the installation on the COT side and the RT side are quite similar, the procedureis valid for COT and RT.

5.2 General Installation

5.2.1 Environment Check and Preparation

5.2.1.1 Required Power SupplyThe central office or the cabinet that houses the SM-B1 should provide the nominal –48Vdc (the rangis from -36Vdc to -63Vdc) or the 220 Vac (the rang is from 230Vac to 110Vac). If the powerprotection is desired, both AC and DC should be connected. (Refer to 2.3.1 power Protection).

5.2.1.2 Power-on ProcedureThe next procedures must be followed and performed in using power.

(1) Make sure our system is powered off.

(2) Connect a) -48V; b) ground for the -48V; c) frame ground to our system

(3) Measure -48V power to make sure that it is correct and no short circuit between the -48V and theframe ground.

(4) Turn on the power switch on our system

5.2.2 E1/T1 Port ConnectionLow speed E1/T1 interfaces (h1 or h2 in FIGURE 5-1 on Page 1) are provided through the DB-37connectors.
