Channelized T3 Trunk Card
The Cisco AS5800 universal access server supports a channelized T3 (CT3) ingress interface that
provides asynchronous aggregation of channelized interfaces and multiplexing on a single T3 facility.
The CT3 trunk card is installed in the Cisco 5814 dial shelf chassis in slots 0 to slot 5. The
Cisco AS5800 currently supports as many as two CT3 trunk cards.
This chapter explains how to remove and replace a CT3 trunk card in the Cisco 5814 dial shelf chassis,
and also includes steps for verifying and troubleshooting your trunk card installation and configuring
CT3 Trunk Card Overview
The CT3 trunk card contains an onboard M13 multiplexer, which multiplexes 28 separate T1 lines into
a single T3 line. Each CT3 trunk card installed in the Cisco 5814 dial shelf contains all necessary
functionality to terminate link signaling and incoming digital calls.
Figure 3-1 shows the CT3 trunk card.
