Chapter 7 4-Port Channelized OC-3/STM-1 Line Card Overview

Line Card Summary

The 4-port channelized OC-3/STM-1 line card uses fractional T1 (n x DS0), DS-1, E1, fractional E1

(n x DS0) and DS3 IP services to connect ISP customers to the network backbone. It provides full duplex

operation at OC-3 bandwidth rates using a (single-mode) fiber optic port that provides the Cisco 10000

series router with one interface that connects up to 768 individual channelized options.

The 4-port channelized OC-3/STM-1 line card has four single-mode, intermediate-reach LC

OC-3/STM-1 duplex optical connectors.

The line card can be configured into either SONET or SDH mode.

• When configured for SONET mode, each OC-3 port carries three DS3 (full rate, subrate, or

channelized down to DS1) channels, or 84 individual DS1s, each capable of carrying a single

channel at full or fractional rates.

• When configured for SDH mode, each STM-1 port carries three DS3 (full rate, subrate, or

channelized) channels, 84 individual DS1s, or 63 individual E1s; each DS1/E1 is capable of carrying

a single channel at full or fractional rates. The line card runs in either E1 or T1 mode, but no mixture

of T1/E1 is supported.

Each STM-1 port supports up to 192 channels, for a total of 768 channels per line card. The total number

of channels cannot exceed the chassis scaling limits.
