Figure 4 1-Port Channelized OC-12/STM-4 (OC-3) Line Card
1-Port Channelized OC-12/STM-4 (DS3) Line Card Product Overview
The 1-port channelized OC-12/STM-4 (DS3) line card provides 12 channels of DS3 multiplexed over a
single 622-Mbps OC-12/STM-4 port. The 1-port channelized OC-12/STM-4 (DS3) line card interfaces
through an Add Drop Multiplexer (ADM) with other DS3 line cards at DS3 line rates in a configuration
that usually consists of a Cisco 7200 Series Router and a Cisco 7500 Series Router configured with the
packet-over-E3/T3 (POET) port adapter, or a third-party T3 data service unit (DSU) such as Digital Link,
Larscom, or Kentrox.
The 1-port channelized OC-12/STM-4 (DS3) line card interfaces with the Cisco 12000 Series Router
switch fabric and provides one OC-12/STM-4 duplex SC single-mode intermediate-reach Synchronous
Optical Network (SONET) connection. Figure 5 shows the front view of this line card.
