This document explains the cross-connection matrix for STS-1 and VT1.5 circuits in the Cisco 15454 system, detailing EC1 card mapping and ASIC capacities.
This document provides information about the cross-connection matrix for the STS-1 and VT1.5 circuits within the Cisco 15454 system. It details the mapping of STS-1 and VT1.5 circuits, including the capabilities of the EC1 card, STSX ASIC, and VTX ASIC. The text explains how to provision circuits and utilize the available bandwidth between the cross-connect cards and the backplane.
| Maximum number of STS-1 circuits on XC card | 144 |
|---|---|
| Maximum number of VT1.5 connections on XC-VT card | 336 |
| Maximum number of STS-1 circuits on VTX ASIC | 24 |
| Maximum VT1.5 circuits per STS-1 circuit | 28 |
| Maximum bandwidth of XC-VT in VT1.5 connections | 336 |
The XC card can provision a maximum of 144 simultaneous STS-1 connections.
The XC-VT card supports a maximum of 336 VT1.5 connections.
A single STS-1 circuit can carry up to 28 VT1.5 circuits.
