T1/PRI and E1/PRI Cards

This chapter describes the Quad and Octal T1/PRI and E1/PRI cards. This chapter includes the

following sections:

Overview

Cisco IOS Software Required Removing and Installing Cards

Setting Input Impedance for E1/PRI WAN Cards

Configuring Cards

OverviewThe Cisco AS5300 universal access server is a versatiledata communications platform that provides

the functions of an access server, router, and digital modems in a single modular chassis. The access

server is intended for Internet service providers (ISPs), telecommunications carriers, and other

service providers that offer managed Internet connections, and also medium- to large-sized sites that

provide Voice over IP, and both digital and analog access to users on an enterprise network.

By terminating both analog and digital calls on the same chassis simultaneously, the access server

provides you with a clear, simple, and easy migration path from todays analog dial access services

to tomorrows digital dial access services.

The access server includes three slots in which you can install a combination of cards. In any one

slot you can install your choice of:

Quad T1/Primary Rate Interface (PRI) or E1/PRI card with or without serial support

Octal T1/PRI or E1/PRI card with serial support

Both types of cards contain Bantam jacks for troubleshooting purposes. In the Quad cards, the jacks

are controlled through the hardware, and in the Octal cards they are controlled through the software.

In the remaining two slots you can install your choice of a MICA or a Microcom modem card. See

the chapters Microcom Modem Cards and MICA Modem Cards for details.

Note The Octal and Quad cards with serial support do not support Microcom cards.

Table 2-1 Memory Requirements for Cards

Quad T1/PRI and E1/PRI CardsYou can install one of two types of Quad cards in any unpopulated slot of the access server chassis:

Quad Cards Without Serial Interfaces

Quad Cards With Serial Interfaces

Both types of cards are described in the following sections.

Quad Cards Without Serial Interfaces

Quad T1/PRI Card

The Quad T1/PRI card (see Figure 2-1) without serial interfaces includes four RJ-45 ports. Cables

are not included with the card; however, port pinouts are listed in Appendix B, Cabling

Specifications. Note that these boards support both MICA and Microcom modems.

A 10-position rotary switch allows the user to choose which of the four ports is selected for

monitoring through the Bantam jacks (TXMON, TXIN, TXOUT and RXMON, RXIN, RXOUT).

The LED labeled MON at each port lights to indicate that port has been selected for monitoring.Only one port can be selected at a time. None of the ports is selected when the switch is set to the

OFF position.

Figure 2-1 Quad T1/PRI Card Without Serial Interfaces

Cables are not included with the card. However, cable specifications and port pinouts are listed in

Appendix B, Cabling Specifications.

Quad E1/PRI Card

The Quad E1/PRI WAN card (see Figure 2-2) without serial interfaces includes four RJ-45 ports for

terminating 120-ohm balanced lines or 75-ohm unbalanced lines. Cables are not included with the

card. However, cable specifications and port pinouts are listed in Appendix B, Cabling

Specifications. Note that these boards support both MICA and Microcom modems.

A 10-position rotary switch allows the user to choose the number of ports that are terminated as

75-ohm unbalanced lines. If the LED labeled 120 at each port is on, it indicates the input impedance

of that port is set to 120 ohms. If it is off, the impedance is set to 75 ohms.

Octal T1/PRI and E1/PRI Cards

Jumper settings on the card can be used to configure the 75-ohm unbalanced ports so the receive

shield is connected to ground. Impedance selection switch settings and receive shield jumper

positions are described in the section Setting Input Impedance for E1/PRI WAN Cards later in this

chapter.

Figure 2-2 Quad E1/PRI Card Without Serial Interfaces



Quad Cards With Serial Interfaces

This section describes the Quad T1/PRI and Quad E1/PRI cards (see Figure 2-3) with serial

interfaces. Note that these cards do not support Microcom modems.

Note If you are installing a Quad card with serial interfaces on a Cisco AS5300 chassis you already

have, you will need to upgrade the DRAM to 64 MB. You can order the memory upgrade using the

part number MEM-64M-AS53 from Cisco Systems.

Figure 2-3 Quad T1/PRI or E1/PRI Card with Serial Interfaces

The board provides 4 RJ-45 T1 or E1 PRI ports and 4 serial interfaces for backhaul WAN support.

The T1/PRI ports are configured as 100-ohm per port. For the Quad E1/PRI WAN card, the four

ports can be configured as 75- or 120-ohm lines. The factory-set default is 120-ohm. Note that for

the Octal E1/PRI card you change the impedence using a software command. See the Cisco AS5300

Universal Access Software Configuration Guide for details.



Octal T1/PRI and E1/PRI CardsYou can install an Octal E1/PRI or T1/PRI card (see Figure 2-4) in any slot of the access server

chassis. The board provides 8 RJ-45 T1 or E1 PRI ports and 4 serial interfaces for backhaul WANsupport. Note that these cards do not support Microcom modems.

Note If you are installing an Octal card on a Cisco AS5300 chassis you already have, you will need

to upgrade the DRAM to 64 MB. You can order the memory upgrade using the part number

MEM-64M-AS53 from Cisco Systems. The minimum software release for this board is Cisco IOS

Release 12.02(XD).

Cisco IOS Software Required


Figure 2-4 Octal T1/PRI or E1/PRI Card

The T1/PRI ports are configured as 100-ohm per port. For the Octal E1/PRI WAN card, the eight

ports can be configured as 75- or 120-ohm lines. The factory-set default is 120-ohm. Note that,

unlike the Quad E1/PRI card, the Octal E1/PRI card does not include a rotary switch to choose the

input impedence for the ports; you change the impedence using a software control register. See the

Cisco AS5300 Universal Access Software Configuration Guide for details.



Cisco IOS Software RequiredYou require the following software versions:

For the Quad T1/PRI or E1/PRI cards without serial support, you require Cisco IOSRelease 11.2(16)P, 11.3(6)T, or higher.

For the Quad T1/PRI or E1/PRI cards with serial support and the Octal T1/PRI or E1/PRI cards,you require Cisco IOS Release 12.0(2)XD, 12.0(3)T or higher.

Removing and Installing Cards

Caution If you skipped Chapter 1, Safety Warnings, Recommendations, and Tools Required, go back and

read it now. This chapter provides important safety information and a list of tools you need to successfully

remove and install cards without damaging your access server.

Removing Cards

Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with

telephone-network voltages.

Warning Do not work on the system or connect or disconnect cables during periods of lightning activity.
