Line Card Summary
Line Card Summary
The 1-port channelized OC-12/STM-4 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-12 bandwidth rates using a (single-mode) fiber optic port that provides the Cisco 10000
series router with a single interface that connects up to 768 individual channelized options.
The 1-port channelized OC-12/STM-4 line card has one single-mode, intermediate-reach
SC OC-12/STM-4 duplex optical connector.
The line card can be configured into either SONET or SDH mode.
When configured for SONET mode, the OC-12 port carries twelve DS3 (full rate, subrate, or
channalized down to DS1) channels, or 336 individual DS1, each capable of carrying one channel
at full or fractional rates.
When configured for SDH mode, the STM-4 port carries twelve DS3 (full rate, subrate, or
channalized) channels, 336 individual DS1s, or 252 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.
The line card supports up to 768 channels. The total number of channels cannot exceed the chassis
scaling limits.
