M1-3 Overview

The Verilink M1-3 Time Division Multiplexer is designed to aggregate 28 DS1 signals into a DS3 signal. Th i s application module operates with Verilink’s AS3000 product line.

The M1-3 application consists of the following components:

•

M1-3 application module

•

CIM 3113 Rear Connector Module

The M1-3 module is designed to operate with any of Verilink’s AS3000 application modules. M1-3 control is provided by the SCM controller module.

The M1-3 module manages and combines up to 28 T1 datastreams (digitized voice, data, and video applications) into a T3 or fractional T3 datastream. The DS3 port supports C-bit parity and M1-3 M-frame structure for multiplexing DS1 to DS3.

NOTE:

The IMUX and QUAD D ATA appli cation mod ules refe rred to in this manual are due to release in Q3 1999.

Applications

The Verilink M1-3 Multiplexer is used to multiplex multiple T1s from PBXs, routers, digital voice, and video applications into a T3 or fractional T3 service carrier. The far-end equipment can be one of the following:

•

Inverse multiplexers for high speed access and frame relay networking (QUAD/IMUX).

•

Another M1-3 with a full or fractional DS3 interface.

•

Single T1/FT1 QUAD T1.

The M1-3 provides 28 synchronous DS1 payloads to/from the AS3000 system midplane, p roviding a single DS 3 network interface supporting a line rate of up to 44.736 Mbit/s (Figure 1-1).

Network Management

LED Color Codes

Network management for the M1-3 is supported through the SCM using SNMP, Verilink’s Node Manager software, or the Craft (ASCII) interface. The SCM supports the following MIBs for the M1-3 multiplexer application:

•

Verilink Enterprise M1-3 MIB

•

RFC 1406

•

RFC 1407

The M1-3 front panel supports a Craft interface; however, M1-3 configuration and control is performed using the SCM. The M1-3 is not a standalone application and must be used with the SCM. The SCM manages the nodes system parameters and circuits bet ween the M1-3 and other application modules.

The M1-3 front panel LEDs use the following color codes: Solid Green Element is properly configured and equipment is

operating normally.

Solid Red Indicates a problem or some non-operational

condition occurring within the equipment.

Solid Amber Indicates test mode condition within the equipment.

Timing Options

Inband Management Channel

Detailed informat ion about LEDs can be found in Chapter 4 “Performance Monitoring”.

The M1-3 module supports three modes of timing sources:

Internal

•

internal oscillator.

Network

•

datastream.

External

•

(supports line rate o f up to 44 .7 36 Mb/sec) that is conne ct e d to the BNC connector labelled connector module.

When working with other modules, set the M1-3 to use the shelf timing table, since the M1-3 always operates with another module.

The M1-3 module provides support for inband channel management in C-bit parity applications. The M1-3 transmits three messages per second, and uses the standard inband management protocol.

—Reference timing is derived from the free-running

—Reference timing is derived from the incoming DS3

—Reference timing is derived from the external clock

NOTE:

This section provides the details to create three type of M1-3 circuits in an MLS. As you read, the example uses multiple configurations and makes the following assumptions:

No further menu options are required for this example setup.

•

That an SCM is in slot 1 with a shelf address of 1. An M1-3 is in slot 6 with the T3 and T1 ports configured, a QUAD T1 is in slot 3, and an IMUX module is in slot 5.

•

Detailed information on each configuration option is provided in Chapter 3, "M1-3 Configuration Options”.

Once the M1-3 module has been in service for at least 15 minutes, meaningful information c an be found i n the perform ance registers. It is suggested that the performance registers be reset after the completion of an installation—in this way, errors accumulated before the installation was completed will not be interpreted as line errors.

Command Description Option

M Line Type—must match what the telco assigns.

• C-bit—In the DS3 C-bit parity format the C-bits are available to provide in-service, end-to-end path performance monitoring of the DS3 signal, and inband data links. C-bit line type is available when all multiplexing occu rs within one mux, as in the M1-3.

• M1-3—Asynchronous framing format that uses all 21 DS3 C-bits for bit stuffing. The standard M1-3 format cannot provide end-to-end parity information. Use this format if the DS3 is split by your telco to multiple far-end locations.

H Coding Type—displays the line options. This option

is carrier-specific when operating on a standard T3 network.

• Bipolar—A T-carrier line-coding system. This system alternates the polarity of consecutive ones bits. This is the normal option.

• Unipolar—A signal s tream in whic h all one bits ar e the same polarity. Intended for use with fiber optics networks.

NOTE: Only bipolar is currently suppor t ed.

R Performance Control—enables/disables

performance control. This option is usually enabled for DS3 except during initialization.

C-Bit

M1-3

Bipolar

Unipolar

M1-3 Alarms

The SCM polls the various modules for al arms. If alarm repo rting is enabled for the node and for the M1-3, the SCM retrieves and sends the alarm to the Craft interface, Node Manager, or an SNMP agent.

Alarms can be automatically sent to a specified printer by setting up the printer address in the SCM management utilities menus.

Alarm Description

Classifications

Alarm List

The Alarm Description column lists the text that is:

•

Printed on the display

•

Sent to the alarm printer

•

Saved to the alarm buffer/database

Verilink classifies alarms into the following severities:

•

Critical

•

Major

•

Minor

•

Warning

•

Info

•

Cleared

Some alarms clear after the user-configured timeout has expired. Other alarms require co rrective action.

•

Cleared alarm, no further ac ti on is required.

•

If there is a loopback present unless you are intentionally testing, remove the loopback. If the loopback is from your telco, verify the loopback with the originating source.

•

If there is a Loss of Frame, you can have a telco or module problem. Activate a remote line loopback to test for Loss of Frame. If there is no Loss of Frame indicated by the test, the problem is with the telco.

•

For a Loss of Signal, check router cables, power, and ports.

•

If you have a self test failure, reseat the module and verify power up and self test. If the M1-3 does not pass after repeated self tests, replace the module.

Alarm Records

Every alarm record that displays on your screen is “active” in the SCM alarm database until corrected. You can do the following with the alarm records:

4-4 Verilink M1-3 U ser Manual

Performance Monitoring

•

Deactivating alarm records is an SCM database management function. While the alarm is active, you can view it on screen using one of the management options in the Craft interface or Node Manager. When deactivated, an alarm is still in the database, but not vie wable on screen. Deactivated alarms can be achieved, printed, or deleted.

•

Printing an alarm record p rints a copy of all active and deactivated alarms.

•

Deleting an alarm record removes it from the database. Deactivate the alarm first, then delete it.

Critical Alarms

Major Alarms

A critical alarm indicates that the node or components of the node have failed. The following alarms are classified as critical :

•

Alarm Indication Signal Second (AISS)

•

Loss of Frame Second (LOFS)

•

Loss of Signal Second (LOSS)

A major alarm indi cates a condit ion where perfo rmance is serio usly affected, for example, a T3 line failure. It prevents data from being reliably transmitt e d across the circuit. When a maj o r alarm is declared, the M1-3 module sends a message to the Craft interface and Node Manager, lights the appropriate LED indicator, and trips the alarm relay.

The following M1-3 error conditions must persist for at least one second for a major alarm to be declared:

•

C-bit Severely Errored Seconds (CSES)

•

P-bit Severely Errored Seconds (PSES)

•

Local Unavailable Second (LUAS)

•

Line Severely Errored Second (LSES)

Minor Alarms

The following error conditions do not affect traffic along the T3/T1 line. They generate a minor alarm:

•

C-bit Coding- Violations (CCV)

•

C-bit Errored Second (CES)

•

Alarm Indication Signal Second (AISS)

•

Line Coding Violation (LCV)

•

Line Errored Second (LES)

•

DS3 Local

Loopback

When a DS3 local loopback is activated, the end user’s T1 equipment and/or DTE is looped on itself through the M1-3 circuits at the DS3 port. The local loopback can be used to check the circuit path from the equipment through the module and back. The M1-3 also passes the equipment signal to the network. All other loopbacks in progress are deactivated during a local loopback (Figure 5-8).

Verilink M1-3 U ser Manual 5-5

M1-3 Diagnostics

Figure 5-8 DS3 Local Loopback

DS3 Line Loopback

M1-3

Near End

When a DS3 line loopback is activated, the data received from the network is transmitted back toward the ne twork. The looped signal passes through the M1-3 repeater so that the line loopback can be used to test the circuit from the far-end M1-3 or telephone company (Figure 5-9).

The M1-3 sends the network signal or AIS to the equipment, depending on how the M1-3 is configured.

If network loopbacks are enabled, the line loopback can also be activated by sending the industry-standard inband loop-up code (00001) for at least 5 seconds to an M1-3. It is then deac tivated by sending the correspo nding lo op-down c ode (0 01) for the sam e time period.

The FEAC loopback is only applicable when in the C-bit mode. This option is disabled when operating in M1-3 mode. When a DS3 farend line loopback is activated, the data received from the network is transmitted back toward the network. The looped signal passes through the M1-3 repeater so that the line loopback can be used to test the circuit f rom the near-end M1 - 3 or tel ep h o ne com pany (Figure 5-10).

The FEAC channel is a part of the overhead bits in a DS3 circ uit with C-Bit framing. Equipment in the telco cloud can interfere with the loop-up signal.FEAC must be enabled at both ends of the circuit. See Chapter 3 “M1-3 Configuration Options”.

When a T1 far-end line loopback is activated, the data received from the network is transmitted back toward the near end. The looped signal passes through the M1-3 repeater so that the line loopback can be used to test the circuit from the near -end M1-3 or telephone company (Figure 5-17).

Transmit Alarms Menu

The transmission of five different alarms for testing purposes. When an alarm option is enabled at the near end (a yellow alarm for example), the near-end M1-3 transmits that alarm code to the farend M1-3. When the alarm code is received at the far end, the farend M1-3 reports it has received that alarm in the alarm buffer.

Only one of the five alarm options should be activated at a time. Transmitting multiple al arms can cause erroneous alarm r e po rts. For example, if a yellow alarm is indicated, the AIS, FEBE, FEAC, and Idle code canno t be generated and detected success fully. The yellow alarm sets X-bit=0, Idle code se ts X-bit=1 , and sends pat tern 1100 on the datastream. The AIS has X-bit=1, C-bit=0, and information field of 1010. Therefore, attempting to detect multiple alarms at the same time can result in an erroneous data report.
