Cisco AS5850 24-Port E1/T1 Termination Card

The Cisco AS5850 24-Port E1/T1 Termination Card (Figure 4) is a Channelized E1/T1 trunk card that provides physical termination for up

to 24 E1 R2s, PRIs, or IMTs [add the caption] The Cisco AS5850 Universal Gateway using four 24-port interface cards can fully terminate

up to 86 E1 trunks or 96 T1 trunks. Any of the E1/T1 interface ports on these trunk cards can be configured independently of any other

interface. Therefore, users can software configure a variety of E1 trunks and ISDN PRI trunks (each connected to a different switch type),

all within the same Cisco AS5850 platform.

The following is a brief description of the trunk types supported:

●

CAS is supported for T1 and E1 trunks, with R2 signaling for E1.

●

IMT is supported when used with an SS7 signaling controller.

●

Many countries require an E1 R2 variant; per-country defaults are provided for supervisory and inter-register signaling.

●

Universal access (analog modem or digital calls) is supported when an interface is configured for ISDN PRI signaling. PRI

signaling is available for both T1 and E1 trunks. When configuring an interface for PRI signaling, the identity of the switch

at the other end of the PRI circuit is imperative.

Nonintrusive monitoring of individual E1/T1 PRI signals is available at the front of the E1/T1 termination card through standard 100-ohm

bantam jacks. Cisco supports all the major switch types and is actively pursuing new features of interest to service providers that can be

supported by these switches. Table 1 lists supported switch types and their features.
