Verilink DIDCSU 2912 User Manual 1-1

Chapter

1DIDCSU 2912 Overview

This manual describes the DIDCSU 2912, a Dual Integrated Data

Service Unit/Channel Service Unit with two E1 network ports or two

T1 network ports, as well as two synchronous serial data ports.

Organization

This chapter consists of an overview of the product. Since the

DIDCSU 2912 can be used on either North American T1 circuits or

international E1 circuits, the remaining content of this manual is

divided accordingly.

Chapter 2, DIDCSU 2912 Quick Set-Up, presents two example

configurations, the first for the T1 mode and the second for the E1

mode.

Chapter 3, DIDCSU T1 Version, provides complete details on all the

T1 version administrative, configuration, performance and

diagnostic functions.

Chapter 4, DIDCSU E1 Version, provides complete details on all the

E1 version administrative, configuration, performance and

diagnostic functions.

Where the Verilink ASCII terminal interface (Craft interface) is

discussed, this manual assumes the module is used with an NCM

2000 Node Controller Module. The menus and options will be

similar when the module is accessed directly via the onboard LOCAL

port.

The DIDCSU can operate as a standalone module or as part of an

NCM 2000 node. Circuits may be built between ports on DIDCSUs in

the same shelf only when an NCM is present. In the absence of an

NCM, the DIDCSU can be the shelf controller.

Features

The DIDCSU 2912 supports a number of features and modes of

operation.

T1/E1 Digital

Transmission

Facilities

The DIDCSU 2912 multiplexes digital data and video traffic onto a

T1 or E1 transmission facility. Each port provides T1/E1 bandwidth

of n × 56 kbit/s or n × 64 kbit/s trunks.

DIDCSU 2912 Overview

1-2 Verilink DIDCSU 2912 User Manual

The aggregate data rate from terminal equipment can be up to one

of the following:

Table 1-1 Data Rates

Crosspoint

Switch The DIDCSU module provides flexibility for designing data paths

with incoming and outgoing channels set up for data or video

traffic. You can also cross-connect DIDCSU circuits through the

AS2000 midplane to certain other modules. However, an NCM 2000

module is required. Refer to the NCM 2000 User Manual for more

information on this feature.

Alarm

Management DIDCSU 2912 alarms can be viewed using the Craft interface. When

used in conjunction with an NCM, three additional access methods

are available: Telnet, SNMP, or the Verilink proprietary GUI network

management program—Node Manager.

Diagnostics The DIDCSU 2912 provides line (LLB), data port (DPL), repeater

(RLB), and payload (PLB) loopbacks. Test patterns can be used with

or without the loopbacks.

Advanced

Programmable

Architecture

All DIDCSU system hardware and software components can be

independently upgraded with product options and firmware

upgrades. The firmware can also be replaced using upgraded chips.

Additional DIDCSU modules can be added within a node to increase

T1/E1 channel capacity. CIMs and other modular components can

be added, upgraded, or replaced independently.

Time Division

Multiplexer The DIDCSU 2912 accepts high-speed data from routers, front end

processors, video codecs and other types of data terminal

equipment. It multiplexes this data into some number of 56 kbit/s

or 64 kbit/s DS0 timeslots and either passes them out a network

port, or with an NCM as node controller only, onto a shelf midplane

for connection to another module.

T1 or E1 Timeslots Data Rate

24 T1 Timeslots n × 56 kbit/s (up to 1.344 Mbit/s) (n =1—24)

24 T1 Timeslots n × 64 kbit/s (up to 1.536 Mbit/s) (n =1—24)

31 E1 Timeslots n × 64 kbit/s (up to 1.984 Mbit/s) (n =1—31)

DIDCSU 2912 Overview

Verilink DIDCSU 2912 User Manual 1-3

CSU/DSU The DIDCSU 2912 can be used in a simple configuration in which it

functions as two T1 or E1 CSU/DSU units. Data from the first data

port can be mapped to the first network port, while data from the

second data port is mapped to the second network port. Except for

a common transmit clock source, these two CSU/DSU functions are

independent of each other

Drop, Insert, and

Bypass Mode The DIDCSU 2912 supports drop, insert, and bypass functionality

via a crosspoint switch.

The drop, insert, and bypass configuration reduces the number of

network links between different sites. The three interconnected

sites in Figure 1-1 can have certain applications, such as video

conferencing, which are used only occasionally. These sites can

allocate a specific bandwidth of the T1/E1 line for the weekly one-

hour video conference, and at other times, use the bandwidth for

other purposes.

DIDCSU 2912 Overview

1-4 Verilink DIDCSU 2912 User Manual

The DIDCSU 2912 does the necessary cross-connections to ensure

that the local area network signal from Building 1 terminates (or

drops) at Building 2, the video circuit is added (inserted), and the

outgoing data stream is sent on to Building 3.

1. Video data from Building 1 is destined for Building 3 but,

because there is no direct connection, is sent to Building 2

over a network line. The node at Building 2 cross-connects the

video data to timeslots on the network line that links Building

2 and Building 3. The video circuit arrives at Building 3.

(Bypass)

2. LAN A in Building 1 uses timeslots on the network line to

Building 2 for transmitting and receiving data from LAN B.

(Drop)

3. LAN C in Building 2 uses timeslots on the network line to

Building 3 for transmitting and receiving data from LAN D.

Chapter

2DIDCSU 2912 Quick Set-Up

This chapter is divided into two main sections. The first section

provides step-by-step procedures for installing your DIDCSU 2912

module on a T1 circuit. The second portion of this chapter provides

step-by-step procedures for an E1 installation.

T1 Quick Set-Up

This quick configuration guide makes the following assumptions:

•You are installing the DIDCSU 2912 in a dual-line shelf with an

NCM 2000 module.

•You are connecting two T1 facilities—one an FT1 using 12

DS0s, the other a full T1 with 24 DS0s—to the two network

ports of the DIDCSU 2912.

•The full T1 connects to Net Port 1 and all of the timeslots are

mapped to Data Port 1, the fractional T1 is connected to Net

Port 2 and the first 12 DS0s are mapped to Data Port 2.

•The NCM 2000 controller module is in slot 1 and the DIDCSU is

in slot 2.

Figure 2-1 Example Configuration

NOTE: These procedures may not match your configuration. Use this

chapter as a guide for equipment installation. DIDCSU T1

Version has complete details on configuration of the T1

mode.

Connect to Craft

Port Connect the modular (RJ-11) end of the Craft cable (P/N 458-

102119-008) to the port labeled LOCAL on the front panel of the NCM

controller module. Connect the other end of the Craft cable to your

PC or terminal.
