For the appearance and connection of a HIM-CL1P/HIM-CL2P interface cable, see"Connecting an optical interface cable."HIM-CLS1P (RT-HIM-CLS1P-H3)/HIM-CLS2P(RT-HIM-CLS2P-H3)The HIM-CLS1P and HIM-CLS2P are high-speed OC-3/STM-1 (155 Mbps) CPOS E3/T3 interfacemodules. They can also operate in packet over SONET/SDH (POS) mode. The HIM-CLS1P provides oneSFP port and the port is provided with two LEDs, which indicate the port running status and fault detectionstatus, respectively. The HIM-CLS2P provides two SFP ports.The HIM-CLS1P/HIM-CLS2P has the following features:• Connects to the processor through a 10-Gbps high-speed bus. Each OC-3/STM-1 POS interfacecan be channelized into three E3s or T3s.• Each E3/T3 channel supports the subrate processing capability, providing users with a variety ofbandwidth options.• Receives multiplexed E3/T3 circuits on a pair of fibers through a channelized interface, savingmany link resources, the occupied area, and the cost of local networks and devices fortelecommunication service providers and large enterprises.• Supports IP and MPLS traffic and MP with up to three E3s or T3s in each MP bundle.
