  • Page 12: Channelized T3 Overview

    The PA-MC-T3-EC does not support E1 into channelized T3. Channelized T3 Overview In the channelized mode of operation, a PA-MC-T3-EC T3 link is channelized into 28 DS1 data lines in an industry standard multiplexing format. Each of the T1 lines contains 24 time slots of 64 or 56 kbps each. The T1 lines can support one or more user data channels which appear to the system as serial interfaces.

  • Page 13: Chapter 1 Overview

    T3 Specifications The PA-MC-T3-EC T3 port is designed to receive and transmit at the DSX-3 level while driving and receiving from 75-ohm coaxial cables (ATT 734A or equivalent quality coaxial cable). The T3 port connects directly to any equipment with DSX-3-level BNC connectors.

    STAT US Identifying Interface Addresses This section describes how to identify the interface addresses used for the PA-MC-T3-EC in Cisco 7200 VXR routers. Interface addresses specify the actual physical location of each interface on a router or switch. The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number.

The interface addresses of the interfaces on the PA-MC-T3-EC in port adapter slot 1 are 1/0 and 1/1 (port adapter slot 1 and interfaces 0 and 1). If the PA-MC-T3-EC was in port adapter slot 4, these same interfaces would be numbered 4/0 and 4/1 (port adapter slot 4 and interfaces 0 and 1).
