TDM/MCMP Common Capabilities

The TDM/MCMP option is an additional circuit card. TDM capability allows up to six independent ports to share one standard digital point-to-point facility. MCMP capability allows up to six ports to share one standard 56 kbps multipoint facility.

The TDM option can be software-defined to provide one of the following:

• TDM

• Digital bridge capability

The MCMP option can be software-defined to provide one of the following:

• MCMP

• TDM

• Digital bridge capability

Common features are:

• Async/Sync conversion: Provides point-to-point

and multipoint asynchronous-to-synchronous data conversion for DTE ports for both EIA-232 and V.35. The DSU can send asynchronous data over a synchronous network.

• FEP port sharing: Provides a method of

connecting a front-end processor (FEP) to two consecutive ports to broadcast the same message over the network and the shared ports. Up to three separate FEP port-sharing groups can be selected. Each group consists of two adjacent ports (1 and 2, 3 and 4, 5 and 6).

• Elastic store per port: Provides a transmit elastic

store buffer for each port to support extended circuits. Supports both digital and analog extensions.

• Switched-carrier emulation: Provides optional

switched-carrier emulation for each port for both inbound (toward the control DSU) and outbound (toward the tributary DSU) directions.

NOTE

The V.34 DBM does not support applications requiring Ext to RXC DBM transmit clock source configurations, including:

• Multipoint backup — Central-Site Bridge — Extended Site Bridge — FEP Backup Modes

• Tail circuits

TDM Capability

TDM capability allows up to six independent ports to share one standard digital point-to-point facility. Additional TDM capability includes the following features:

• Three standalone versions: Model 3610 has three

TDM models:

— DSD (digital sharing device) — Flex — Standard

• Flex option: There are two versions of the

TDM/Flex standalone model:

— 2-port TDM/Flex — 6-port TDM/Flex

With either flex option installed, each port can be set independently as either an EIA-232 or V.35 interface.

• Port capacity: Model 3610 provides:

— Up to six EIA-232 or V.35 ports with DSD or

Flex models

• Data rates: Operates up to 64 kbps full-duplex.

• Primary network interface: The alternate Port 1

on the DSU provides an internal aggregate data stream. When the Network Interface configuration option is set to forced on, the unused V.35 or EIA-232 interface functions as an external TDM. A connection can be made to any multiplexer or DSU/CSU.

When the DSU powers up, data automatically switches to the alternate Port 1. No DDS connection is required. Any cluster controller requiring subrate can be supported at a remote site. Using the alternate Port 1 for the network interface supports:

— DBM, TDM, and MCMP options — Disruptive and Nondisruptive diagnostics — Rate Adaption and In-Band Framing — Aggregate data rates of 64, 56, 19.2, 9.6, 4.8,

and 2.4 kbps

• Digital bridge: Performs digital bridge functions

and supports many applications, including dedicated multipoint dial backup and multipoint LADS operation.

— An EIA-232 or V.35 Port 1 option and five

EIA-232 ports for the Standard model

Model 3611 uses the Standard model and a six-port DTE connector module. The connector module includes six 25-pin DTE connectors and a 26-pin high-density connector for the V.35 alternate Port 1 option. Model 3611 does not have V.35 for Ports 2–6.

• Port speeds: Individual TDM ports (1 through 6)

can be set to a variety of speeds. The sum of the port speeds cannot exceed the DSU data rate.

• Digital sharing: Allows two groups of consecutive

ports to share the same TDM channel. All ports in a digital-sharing group operate at the same speed and receive the same data.

• Flexible device control: Provides the same

diagnostic capabilities as a point-to-point 3600 Series DSU without the TDM option. Allows control of the TDM option from the front panel, an async terminal, or a 6700 or 6800 Series NMS.

• Point-to-point backup: Allows a DSU with TDM

to have a DBM installed for point-to-point dial backup. If backup is at a different port speed than the DSU’s port speed, TDM operation automatically changes to a second predefined port speed to support dial backup operation at a lower port speed.

• Channel capacity: Provides up to eight channels,

which can be matched to all enabled ports.

• Three standalone versions: Model 3610 has three

MCMP models:

— DSD (digital sharing device) — Flex — Standard

• Flex option: There are two versions of the

MCMP/Flex standalone model:

— 2-port MCMP/Flex — 6-port MCMP/Flex

With either flex option installed, each port can be set independently as either an EIA-232 or V.35 interface.

• Port capacity: Model 3610 provides:

— Up to six EIA-232 or V.35 ports with DSD or

Flex models

— An EIA-232 or V.35 Port 1 option and five

EIA-232 ports for the Standard model

• Multipoint dial backup: Provides multipoint

service restoration. When Network Interface configuration option is set to AggSw, the DSU provides an internal aggregate data stream for diagnostics and framing on alternate Port 1. The alternate Port 1 can be connected to an extended bridge.

NOTE

The V.34 DBM does not support applications requiring Ext to RXC DBM transmit clock source configurations, including:

• Multipoint backup — Central-Site Bridge — Extended Site Bridge — FEP Backup Modes

• Tail circuits

DSU with Digital Bridge Capability

Digital bridging is used primarily for dedicated multipoint dial backup. A digital data service (DDS) multipoint network can be backed up with:

• V.32 analog DBM

• Switched 56 kbps calls between the central-site and

remote-site DBMs that are connected by the digital bridge

• ISDN (Integrated Services Digital Network)

• Digital sharing: Allows up to three digital-sharing

devices at each tributary by assigning channels to more than one port. All ports operate at the same speed and receive the same data.

MCMP capability allows digital sharing and multiplexing simultaneously at any tributary site.

• Number of addressable devices: Supports up to

40 tributary DSUs or 20 tributary DSUs with DBMs, each equipped with an MCMP circuit card.

• Channel speeds: Speeds of the individual channels

can be set to a variety of speeds. The sum of the channel speeds cannot exceed 48 kbps.

The digital bridge capability is dedicated to a single DSU. The DTE connected to the DSU is usually the controlling DTE of a multipoint network. Configure either the TDM or MCMP option to provide the digital bridge capability.

The digital bridge capability, when used to support dedicated multipoint dial backup, includes the following features:

• Number of tributaries: Provides dedicated

multipoint dial backup for up to 20 tributary DSUs. Four additional DSUs with TDMs are required for each configured extended bridge (EBrdg).

COMSPHERE 3600 Series Data Service Units

• Partial and full backup: Provides multipoint dial

backup for both partial and full backup on DDS multipoint circuits, depending on configuration.

• Security: DBMs provide multiple levels of call

setup security.

• Restoration: When the DSU rate equals the DBM

rate, preconfigured tributary DSUs can automatically drop the backup connection and switch back to the DDS facility when the DDS network is restored.

LPDA-2 with TDM or MCMP

The SNA Diagnostic Interface uses the Release 2 Link Problem Determination Aid (LPDA-2) protocol. The LPDA-2 protocol is installed on the DSU circuit card. When enabled:

• With TDM or MCMP, LPDA-2 is only supported

on Port 1.

• For digital sharing, all ports are supported.

Powering Up the DSU

CAUTION

The power cord contains a 3-wire grounding-type plug which has a grounding pin. This is a safety feature. Grounding of the unit is vital to ensure safe operation. Do not defeat the purpose of the grounding plug by modifying it or by using an adapter.

Prior to installation, use an outlet tester or voltmeter to check the ac receptacle for earth ground. If the power source does not provide a ground connection, consult an electrician to determine another method of grounding the unit before proceeding with the installation.

2. Turn the card around and re-insert. In the example

above, the card reads THIS SIDE FACES REAR FOR V.35.

3. Continue with next section, Reassembling the DSU.

TDM/MCMP Installation and Setup

Power-Up Routine

When you apply power the first time, the DSU

performs a power-up routine and:

• Determines what hardware options are installed.

This may include MUX to represent TDM or MCMP.

• Automatically runs a Device T est on the DSU and

each installed hardware option. All front panel lights flash on and off.

• If a TDM or MCMP is installed, MUX appears as

Pass or Fail on the LCD.

Refer to your User’s Guide for power-up messages and steps for saving and changing configuration options. Refer to Table D-1 for Configuration Error messages.

If a Fail message appears or an installed hardware option does not appear, see Appendix D, Troubleshooting

and Front Panel Messages. Refer to Document No.

3610-A2-GB46 for DSU troubleshooting and Document No. 3610-A2-GB49 for DBM troubleshooting.

Reconfiguring Ports

If you have a TDM/Flex or MCMP/Flex with a firmware version 6.33 or greater, you can configure each port for either EIA-232 or V.35 interface compatibility from the front panel, an async terminal, or an NMS.

To set a port for EIA-232 or V.35 operation:

Procedure

1. From the Home screen, select Local (F1). The

following screen appears on the LCD.

Local Mode: Stat Bckup Test

Confg Ctrl

2. Press the

key until Confg appears.

DTE Connections

Make the DTE connections as described in the User’s

Guide, Document No. 3610-A2-GB46.

In a TDM or MCMP application, all ports default to EIA-232 port interface operation. For TDM/Flex or MCMP/Flex, Ports 1 through 6 can be set individually to EIA-232 or V.35 by using the MUX port configuration options.

For an EIA-232 connection with distances greater than 50 feet or data rates higher than 19.2 kbps, use short, high quality cable with low capacitance and a DTE capable of supporting the distance and data rate.

When Port 1 requires a speed higher than 19.2 kbps, it is recommended that the port interface be set to V.35. An interconnect cable is required for every port (2 through 6) that is set to V.35 interface.

3. Select Confg (Configuration branch). The

Configure screen appears.

4. Select Opts. The Load from screen appears.

5. Select Activ (F1). The Edit/Save screen appears.

Overview

You can manage a 3600 Series DSU from:

• The front panel

• An async terminal

• A 6700 or 6800 Series NMS

The front panel menus are organized as a branching hierarchy or menu tree. Refer to these reference materials as you proceed through the DSU’s menus.

• Appendix A contains this menu tree.

• Chapter 4 presents MCMP, TDM, and digital bridge

configuration option tables.

• Appendix B contains Configuration Worksheets.

Front Panels

The front panel is the user interface to the DSU. There are two types of front panels:

Front panel operation does not vary with the addition of DSU options (DBM, TDM, MCMP, or SNA Diagnostic Interface). However, menu or selection displays may vary based on installed options. Refer to the User’s Guide for basic front panel, display, keypad, and menu function information.

A Model 3611 DBM with Primary Core set to Yes does not function as a DSU and is labeled with an alpha code: DBM-D, DBM-I, DBM-S, and DBM-V. A DBM-X is a Model 3611 DBM-D, DBM-I, DBM-S, or DBM-V. Refer to Document No. 3610-A2-GB49 for DBM details. Any MUX function is operational with a DBM-X.

Front Panel Operation

Status Indicators

The status indicators on the Model 3610 DSU’s front panel and on the Model 3611 DSU’s faceplate continuously provide information on the current operating condition of the DSU.

Refer to the COMSPHERE 3000 Series Carrier Installation Manual for SDCP status indicator tables; these are unchanged by the presence of a TDM or MCMP circuit card.

The status indicators of the carrier-mounted Model 3611 DSU are spread across the SDCP, DSU, TDM, or MCMP faceplates. Refer to T able 3-1 for TDM

and MCMP status indicators and descriptions.

A voltage spike on the power line or momentary loss of power may cause an alarm. The DSU automatically reloads the TDM or MCMP configuration options. When the reload has completed, the Alrm LED goes Off and the TDM or MCMP OK LED comes ON.

Green TDM or MCMP mode: Shows ports

currently being monitored. The status of the port’s leads is displayed on the faceplate of the associated DSU.

One of the six ports can be monitored at any given time; the port to be monitored is selected at the SDCP.

When Network Interface is set to aggregate switch (AggSw), all ports are monitored and all LEDs will be ON.

Bridge mode: The port LEDs perform differently. The LEDs indicate which ports had RTS ON during the last second.

When the port is connected to a DCE device, the port RTS becomes the received LSD signal of the DCE device. The LEDs indicate which ports had upstream activity during the last second.

On the aggregate data path, Local Loopback (LL) and End-to-End (EE) tests can be run.

Performing tests on the aggregate data stream tests the entire bandwidth, and in-band transport communication is lost. For tests such as aggregate Digital Loopback (DL), the control DSU reports a No Response or a TribTimOut alarm for downstream devices.

When the tributary DSU receives a test request from the control DSU, any locally initiated test in progress is aborted.

NOTE

Running a test can affect your application data or may cause your application session to be dropped depending upon the protocol, front-end processor, or time-out parameters. No data or acknowledgment messages will be transmitted while the test is in progress.

While performing a multiplexing function for a DSU, tests can be requested on individual ports or on the aggregate data path. Multiplexing functions include:

• TDM or MCMP

• Nondisruptive diagnostics

• Rate adaption

Abort

Abort allows you to stop a test currently running. The DSU is not allowed to run any other test until the test in progress completes or is aborted.

Device Test

The Device (Devic) Test is an internal self-test. If TDM or MCMP is present, the Device T est will test the MUX circuit card also.

Loopbacks

Loopback (Lpbk) provides four loopback tests.

Figure 3-3 shows the direction of each loopback on the

circuit. Refer to Document No. 3610-A2-GB46 for additional loopback information.

Local Loopback

Local Loopback (LL) is session-disruptive; performing

the test disrupts data. The DTE may run a test to determine if the DTE to DSU connection and the DSU itself are functioning properly.

• The DSU must be connected to the DTE.

• Network connection to the DSU is not required.

• For TDM, MCMP, or Bridge mode, the entire data

stream is looped back and all six ports are in Local Loopback.

DTE Loopback

DTE Loopback (DTE) loops back the data path at the

DTE/DCE interface on a per-port basis without affecting the operation of the remaining ports. The DSU with TDM or MCMP permits one active test at a time.

Selecting one port or all active ports (Aggr) loops back the user-transmitted data and the in-band secondary channel transport data when nondisruptive diagnostics are in effect. This disrupts in-band data transport communications.

In Bridge mode, a Basic mode loopback occurs without port selection. For MCMP mode, using the NetIntf selection to perform a Digital Loopback is not a valid command.

Remote Digital Loopback

Remote Digital Loopback (RL) supports testing by an external device, such as a test pattern generator connected to the local DSU’s DTE interface. This tests the local DSU and the DDS circuit.

• In TDM or MCMP mode, asserting power to Pin 21

on Port 1 initiates a V.54 aggregate loopback. This loopback is performed on the DDS circuit unless a dial backup session is active.

• In MCMP mode, the port selected is not

automatically the port placed in loopback at the remote location. If a channel assigned to Port 2 locally is assigned to Port 3 remotely, Port 3 at the remote location is placed in loopback.

Digital Loopback

Digital Loopback (DL) allows manual testing with the

remote end of the circuit. DL can be initiated from a control or a point-to-point tributary.

Digital Test

The Digital T est (DT) verifies operation of a pair of

DSUs and the data circuit between them. When a Digital Test is performed on a specific port, data transmission is not affected on the other ports.

For a DSU operating in single-port mode and having either nondisruptive diagnostics or rate adaption in effect, an additional selection for Aggr or Prt1 appears.

Selecting Aggr tests the looped data path; in-band communication transport data is not allowed.

End-to-End Test

The End-to-End (EE) test analyzes a control and a tributary DSU or DBM and the network circuit between them in both directions independently. Refer to Document No. 3610-A2-GB46 for additional information.

Bit Error Rate Test

The Bit Error Rate T est (BERT) is session-disruptive

and transmits a test pattern to analyze the network circuit. Refer to Document No. 3610-A2-GB46 for additional information.

Dial Tone Test

The Dial T one test (DTone) allows a DBM to test for

dial tone. This selection does not appear in the DSU’s Test branch.

• When a TDM or MCMP is installed and enabled,

the CBrdg and EBrdg selections are also available to place the DSU in Bridge mode.

Poll List

Poll List (PList) maintains or changes a DSU’s poll list

and interfaces with an active internal NMS. A poll list identifies all DSUs or DBMs one level downstream. PList is available for point-to-point tributary DSUs, or tributaries configured for MCMP mode and nondisruptive diagnostics.

• When a DSU is configured for MCMP mode and

nondisruptive diagnostics, both tributary DSU and DBM addresses are included in the DSU’s poll list.

• When configured for MCMP mode and disruptive

diagnostics, only tributary DSU addresses are included in the DSU’s poll list (DBM address is omitted).

• Using the Acquire (Acq) command is an efficient

alternative to the Add command.

When MCMP is enabled:

• The Acq command must be used to successfully

initiate transmissions.

• When adding tributaries to a working network:

— From a control, use the Acq command.

— CBrdg operates as a central-site bridge. — EBrdg operates as an extended bridge.

When a bridge configuration consists of a central-site bridge with one or more extended bridges, digital bridge options must be set for each DSU in the bridge.

• For TDM, MCMP, or Bridge mode, a port number

(6-port version or 2-port version) must be specified before issuing some commands. The results sent back from the DSU may vary depending upon the operating mode (MUX Funct) and port selected.

Refer to T able D-1 for configuration error messages that may appear after pressing SAVE.

— From a tributary, use the Add command.

Command Complete appears when the poll list is

completed. When NMS is polling a control unit or a control unit is polling a tributary, an asterisk (*) appears in the Health and Status display on the right side of the front panel.

Menu (Menu) allows you to disable Full mode. Full

mode displays all menu selections based on installed configuration options and those set by the user. When disabled, an abbreviated set of selections appears. The configuration options that do not display when in Full

Not valid for EBrdg. This configuration value causes the DSU to connect the controlling DTE to the aggregate data path of the digital bridge, and to connect to the DCE port on the digital bridge to the DDS core. Select this value for:

64 to 2.4 kbps – For multipoint dial backup, if the DSU’s speed is higher than the highest possible speed of an analog DBM, configure the digital bridge to operate at a speed that maximizes data throughput. Only full backup is possible, and is set manually from the front panel or initiated by an NMS. When full backup goes into effect, the DSU switches the data path from DTE/DSU to DTE/digital bridge, and enables internal timing at the selected Bridge Rate.

Brdg Timing: Int Next Int Auto Prt Prt2 Prt3 Prt4 Prt5 Prt6 Prev

Bridge Timing. In CBrdg mode, this timing is used when in full backup where the backup is initiated from the Backup branch. In EBrdg mode, the Bridge Timing selected is always used.

Int Auto – Timing taken from any of the ports that have DTR high; primarily used for switched 56 kbps backup. Prt1 to Prt6 – Timing is taken from the specified port. Ports 3 through 6 do not appear when a 2-port TDM/Flex or 2-port

Next Host DSD Prev

Port Control. Specifies how to handle contention between the ports in the ports in a port-sharing group. This configuration option is only displayed if Sharing Device A is enabled.

In multipoint dial backup, ports are not automatically dropped from the digital bridge if the backup call is lost. A DBM that has dropped a backup call will no longer be raising RTS at the digital bridge port and is effectively isolated from the digital bridge. If the backup call was dropped due to a network problem and a new call is successful, the DBM is able to raise RTS and again work with the digital bridge. Does not apply to a V.34 DBM.

Host – No port contention. Causes CTS to turn ON for any port that has RTS turned ON, even if another port is active (RTS ON). The host protocol must enforce the order of transmission to avoid collisions. The connected DBM-D, DBM-I, DBM-S, or DBM-V is not required to have V.13 switched-carrier emulation.

NOTE: In CBrdg mode, Host is the only available setting if Diag Type is set to NonD. In EBrdg mode, Host

should be used if the extended bridge is connected to an MCMP control or a nondisruptive CBrdg.

DSD – Digital-Sharing Device (port contention). Controls CTS to ensure that only one port is active at a time. All ports must be configured with RTS Control set to DTE. A subsequent DTE that has RTS turned ON does not have its CTS turned ON until the first DTE has lowered its RTS. Selection of the next port to transmit when more than one port has raised RTS is based upon the port; the lowest-numbered port has the highest priority.

RTS Cntrl: DTE Next FrcOn DTE Prev

Request-to-Send Control. Controls the internal RTS lead operation.

NOTE: Refer to next configuration option, Transmitter Carrier Select, for a description of constant-carrier and

FrcOn – DSU keeps the internal RTS ON continuously. Any data appearing on the transmitted data (TXD) lead from the

DTE is transmitted immediately . Choose this configuration value for constant-carrier operation. DTE – DSU turns RTS ON when the external RTS is turned ON. CTS is turned ON or Off by the external control signal

RTS. Choose this configuration value for switched-carrier operation.

TxCarrSel: Const Next Const Cntrl Prev

Transmitter Carrier Select. Enables the TDM transmitter circuitry to simulate switched-carrier operation using the V.13 codes on an individual channel. The simulated switched-carrier operation is also referred to as pseudo-controlled carrier (PCC) mode. Required for applications where the receiving DTE expects a raised LSD lead prior to receiving data. Not valid for MCMP.

NOTE: A port may be configured for switched-carrier operation in one direction and constant-carrier operation in the

switched-carrier operation.

other direction. For MCMP mode, this configuration option is ignored except during dial backup when the MCMP Backup

configuration option is set to TDM (Table 4-1) or a V .32 DBM is installed.

Const – Transmit Constant Carrier (constant-carrier operation). The V.13 codes are not sent. The corresponding remote TDM or MCMP port must be configured for Receiver Constant Carrier or Mark (RxCarrSel set to Const or Mark). Configure each port in a digital-sharing group for Constant Carrier operation (TxCarrSel set to Const).

Cntrl – Transmit Controlled Carrier (switched-carrier operation, PCC mode). The DSU transmits the V.13 codes over the DDS line when the port RTS changes state. When RTS is turned ON, the DSU transmits a code that turns ON LSD at the remote TDM or MCMP port before CTS is turned ON at the local TDM or MCMP port. When RTS is dropped, the DSU sends a code that turns Off LSD at the remote TDM or MCMP port. The corresponding remote TDM or MCMP port must be configured for Receiver Controlled Carrier (RxCarrSel set to Cntrl). This selection is not valid if the DSU is part of a Digital-Sharing Device (DSD) group. See Mark selection in the RxCarrSel configuration option.

RxCarrSel: Const Next Const Cntrl Mark Prev

Receiver Carrier Select. Enables the TDM receiver circuitry to simulate switched-carrier operation using the V.13 codes on an individual channel. Not valid for MCMP.

NOTE: Configuration values Const and Cntrl for Receiver Carrier Select are both valid choices for a port belonging to a

Const – Receiver Constant Carrier (constant-carrier operation). The receiving DSU does not look for V.13 codes used

by the V.13 protocol and does not toggle LSD. Cntrl – Receiver Controlled Carrier for switched-carrier operation in PCC mode (see PCC Buffer, next configuration

option). The receiving DSU looks for V.13 codes used by the V.13 protocol that indicate the transition of R TS at the remote TDM port; the receiving DSU toggles LSD as appropriate.

Mark – If 30 consecutive marks are received, received Line Signal Detect (LSD) goes Off at the port. Received LSD goes ON again just before the first space. TxCarrSel must be set to Const at the remote unit. This configuration option is used primarily when the remote DSU has a DSD group.

TDM/MCMP Port Configuration Options*

PCC Buffer: Disab Next Enab Disab Prev

Pseudo-Controlled Carrier Buffer . Intercepts the V.13 codes used by the V.13 protocol so they do not pass to the receiving DTE. This configuration option is only valid when RxCarrSel is set to Cntrl. Not valid for MCMP.

For an asynchronous port configured for switched-carrier operation, set PCC Buffer to Enab. For a synchronous port configured for switched-carrier operation, PCC Buffer can be disabled or enabled, depending on

whether the V.13 codes disrupt communication at the receiving DTE.

NOTE: Enabling this configuration option can corrupt the end-of-message for some synchronous protocols. Enab – Enables PCC Buffer to intercept V.13 codes.

Disab – Disables PCC Buffer. Elast Stor: Disab

Next Enab Disab Prev

Elastic Store. Elastic Store hardware consists of a transmit buffer (register). Serial data from the extended circuit is clocked into the DSU elastic store using a clock (on EIA-232 Pin 24 or V.35 Pins U and W) provided by the extended circuit received clock lead (on Pin 17). The DSU uses its own system timing to clock data out of the buffer.

Elastic Store is reset on power-up, overflow, or after the RTS lead makes an Off-to-ON transition. After reset, the elastic store can drift by ±ā5 bits in TDM mode and ±ā3 bits in MCMP mode before overflow occurs.

Enab – Use Enable if you have an extended network. Disab – Use Disable if you do not have an extended network.

RTS/CTS Del: 0 Next Chang Prev

Request-To-Send to Clear-To-Send Delay. Allows for an additional delay between the time that RTS is turned ON and CTS is turned ON. A delay is sometimes required for multiplexed applications operating in switched-carrier operation with primary channel extended circuits. This configuration option must provide enough delay so that the last DSU in the circuit has time to train and be ready to accept data before CTS is turned ON.

Chang – Set the RTS-to-CTS delay to the desired value, from 0 to 1040 milliseconds in 8 milliseconds increments. Port speeds of 38.4 and higher can only use delays of up to 504 milliseconds.

DTR Alarm: Disab Next Enab Disab Prev

Enab – If the port’s DTR lead turns Off for 30 seconds, the DSU reports an alarm. Disab – Regardless how long the port’s DTR lead is Off, no alarm is reported.

TDM/MCMP Port Configuration Options*

AntiStream: Disab Next Chang Prev

AntiStreaming. Specifies if the port is monitored for streaming terminal alarms. The purpose of Antistreaming is to provide network protection against a streaming DTE (a defective DTE that has its RTS lead constantly turned ON) by disabling the DTE.

If the DTE turns ON RTS longer than the time specified for the AntiStreaming configuration option, the tributary DSU turns ON its alarm indicator and clamps the port’s leads until RTS is turned Off. Although the DTE port is not allowed to send, it is capable of being tested or disabled. A test resets the streaming terminal timer. When the test is completed, the timer starts again.

Upon detecting that RTS is no longer turned ON, the DSU turns Off its alarm and resets the streaming timer, and allows the DTE port to send data once again.

At tributary locations, this configuration option is generally used for digital-sharing operation and for MCMP operation. This configuration option has an effect only at a port configured with RTS Control set to DTE. It is not allowed when RTS Control is set to FrcOn (set in this table).

Chang – Set timer to any value from 1 to 100 seconds in increments of 1, or Disab. When the timer reaches 100, adding to the timer disables this configuration option. With an async terminal, entering 0 (zero) disables this configuration option.

DSR FrcOn: Enab Next Enab Disab Prev

Data Set Ready Forced On. Overrides any other configuration options controlling the Data Set Ready lead.

Enab – DSR remains ON as long as the DSU is working, regardless of tests and network alarms. Disab – DSR functions as an active lead reflecting various test and alarm conditions and other configuration options.

DSR on Tst: Enab Next Enab Disab Prev

Data Set Ready On in Test. Controls the DSR lead during testing. Enab – DSR is ON continuously during testing, allowing a DTE that relies on DSR being ON to send test messages to

the DSU.

Disab – Use to set DSR to Off during testing. Extend Chan: No

Port 1 Speed. Primary DSU port speed in kbps on Port 1. This configuration option is available when MUX Funct = MCMP.

Choose a port speed for Port 1, then press Next to bring up the speed selection menu for Port 2. Continue selecting port speeds for each enabled port until you enter a port speed for all ports. The default for Ports 2 through 6 is Disab. Ports 3 through 6 do not appear when a 2-port TDM/Flex is installed.

NOTE: For all ports, the DSU verifies that the sum of the individual port speeds does not exceed 48 kbps. The data

Channel Assignment to Port 1. At the control site, any of the channels (A through H) can be assigned to any of the six ports (e.g., channel F→Port 1), but you cannot assign a channel to more than one port. For FEP port sharing, the same channel is assigned to both ports in the group. At one or more tributary sites with Port Control set to Host, a channel can be assigned to as many ports as wanted to establish the virtual multiport circuit for that channel. This configuration option is available when MUX Funct = MCMP. Ports 3 through 6 do not appear when a 2-port MCMP/Flex is installed.

Choose a channel assignment for Port 1, then press Next to bring up the channel selection menu for Port 2. Continue selecting channel assignments until channels have been assigned to all ports. The default for Ports 2 through 6 is None.

A to H – Assigns one channel to one port. None – Assigns no channel to Port 1.

Port 1 Speed. Primary DSU port speed on Port 1. Must be set to the same value in the remote DSU. Choose a port speed for Port 1, then press Next to bring up the speed selection menu for Port 2. Continue selecting port

speeds for each port until you enter a port speed for all ports. The default for Ports 2 through 6 is Disab. Ports 3 through 6 do not appear when a 2-port TDM/Flex is installed.

NOTE: Both ports in an FEP port-sharing group must be configured to operate at the same port speed when using the

64 to 1.2 kbps – Sets the port speed. Disab – Sets port speed to 0 (zero) bps.

18.8, 9.2, and 4.4 kbps. For all ports, the DSU verifies that the sum of the individual port speeds does not exceed the data rate set in the DSU’s Rate(Kbps) configuration option. If the sum of the port speeds equals the aggregate data rate, an underspeed port selection is required. Port speeds in DSD and FEP port-sharing groups are only counted once per group when calculating used bandwidth.

When the Async→Sync configuration option is enabled, the following port speeds will not appear: 32, 24.0, 18.8, 18.0, 9.2, 8.4, 4.4, 4.0, and 2.0 kbps.

Underspeed Port. Selects which port is run underspeed to allow for in-band framing, if used. One port must run underspeed if the sum of the port speeds equals the aggregate data rate [Rate(Kbps)]. A port used for asynchronous operation may not be set for underspeed. Ports 3 through 6 do not appear when a 2-port TDM/Flex is installed.

NOTE: Underspeed cannot be used with 18.8, 9.2, or 4.4 kbps port speeds. The DSU verifies that an underspeed port

Disab – No port runs underspeed during primary operation. Prt1 to Prt6 – Selected port runs underspeed during primary operation.

is selected if the sum of the port speeds equals the primary data rate.

* Only appears when MUX Funct is set to TDM. Refer to DSU Port Speed Configuration Options for MCMP

(Table 4-6 ) if MUX Funct is set to MCMP.

Overview

The MUX Setup configuration options are set using the Configuration branch. When an MCMP or TDM circuit card is installed, the following functions are available:

• MCMP mode

• TDM mode

• Digital Bridge mode

• CBrdg

• EBrdg

• Basic mode (MUX = None)

MCMP Mode

When the MUX function is set to MCMP, multichannel multipoint circuitry is activated. All six ports are available for multiplexing, digital-sharing, or a combination of both.

Using a management channel, the control DSU is in constant communication with each tributary DSU. The management channel is included in the MCMP circuitry and transmits data without disrupting user-transmitted data. In Figure C-1, the DDS multipoint circuit is transmitting to three tributaries.

The management channel is also used for framing and an underspeed channel is not required. MCMP can support up to forty addressable tributary devices (40 DSUs or 20 DSUs with DBMs). With multichannel multipoint and digital sharing, up to three digital-sharing groups can be formed at each tributary site.

NOTE

The figures in this appendix use Customer Provided Equipment (CPE) to represent any DTE, LAN, FEP, DDS backup, MUX, or mainframe.

Bridge Mode

In Bridge mode, all ports are assigned to one digital-sharing group. When the MCMP or TDM circuit card is configured as a digital bridge, the control DSU can support dedicated multipoint dial backup, expanded digital-sharing, or multipoint LADS operation.

When the digital bridge is set for automatic backup, partial or full backup occurs as needed. In Figures C-4 and C-5, a DDS multipoint network is operating with three central-site DBMs dedicated to the control DSU and connected to the CBrdg.

If a failure occurs on the DDS line, each of the affected DSUs switches data through the digital bridge to the dedicated DBM. If automatic restoral is enabled, the active DBMs switch back to the DSUs automatically when the DDS network is restored.

Troubleshooting

Confirm the configuration option settings for the items

listed below that apply to your configuration.

• Verify the network, NMS, and DDS connections.

Refer to your User’s Guide, Chapter 2.

• For an Out of Frame Thresh message and facility

alarm, verify that the control and tributary:

— DSU rates [Rate(Kbps)] are set to match the

DDS circuit rate.

— Diag T ype, Port Speed, and 2nd Ch(bps) are set

the same.

• Diagnostic type affects the control and tributary

interaction. Verify that all DSUs are set to the same Diag T ype. Mixed mode is not valid for MCMP.

• For multipoint rate adaption, enabling the

M-PtSymPrt configuration option is not required. With Diag Type of NonD, the default is enable. The control and all tributaries must be set the same.

• For MCMP mode, verify poll list acquire (Acq) is

completed. To add a tributary, use Add or Acq from the tributary.

Messages

This section describes the progress or error messages that may appear on the front panel of the 3600 Series DSU with a TDM or MCMP installed when:

• Executing a command

• An error condition prevents execution

The messages listed here do not include menus, data entry displays, or specific test results; they do give the condition and any action to perform.

Table D-1 lists the configuration error messages that

may appear after pressing SAVE and the verification routine runs.

For command, progress, health and status, and additional configuration error messages, refer to Document No. 3610-A2-GB46.

For configuration error, progress, and health and status messages supporting DBMs, refer to Document No. 3610-A2-GB49.

• To verify the network, request a remote ID and

ensure that you receive all addresses.

• Initiate a Digital T est (DT) and an End-to-End Test

(EE) to verify error free communications.

• Confirm the CTS Lead, RTS Cntrl, TxCarrSel, and

DSR FrcOn configuration option settings.
