▀ Line Cards

Channelized Line Card (CLC2)

The CLC2 is also referred to as the Frame Relay line card. It provides frame relay over SONET or SDH. The CLC2
supports network connectivity through a gigabit interface to connect to the Packet Control Unit (PCU) of the base
station subsystem (BSS) in a mobile network. These interfaces are commonly used with the SGSN product to support
frame relay.
In North America, the card supplies ANSI SONET STS-3 (optical OC-3) signaling. In Europe, the card supplies SDH
STM-1 (optical OC-3). The transmission rate for the card is 155.52 Mbps with 336 SONET channels for T1 and 252
SDH channels for E1.
Each CLC2 provides four optical fiber physical interfaces (ports). The ports are populated by a Small Form-factor
Pluggable (SFP) modules which include an LC-type connector. The ports of the CLC2 supports two types of SFP
modules and cabling, as shown in the following table.

Multi-mode Channelized (STM-1/OC-3)
Optical Fiber Multi-Mode
The CLC2 supports the Star Channel (1 Gbps) for faster FPGA upgrades and is Restriction of Hazardous Substances
(RoHS) 6/6 compliant.
Install the CLC2 directly behind its respective (Active) packet processing card. You may optionally install CLC2s
behind a redundant (Standby) packet processing card. As with other line cards, install the Channelized Line Cards in
slots 17 through 23, 26 through 39, and 42 through 48.

components.
