HIM-CLS1P/HIM-CLS2P
The HIM-CLS1P and HIM-CLS2P are high-speed OC-3/STM-1 (155 Mbps) CPOS E3/T3 interface
modules. They can also operate in packet over SONET/SDH (POS) mode. The HIM-CLS1P
provides one SFP port and the port is provided with two LEDs, which indicate the port running status
and fault detection status, 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
interface can be channelized into three E3s or T3s.
•
Each E3/T3 channel supports the subrate processing capability, providing users with a variety
of bandwidth options.
•
Receives multiplexed E3/T3 circuits on a pair of fibers through a channelized interface, saving
many link resources, the occupied area, and the cost of local networks and devices for
telecommunication service providers and large enterprises.
•
Supports IP and MPLS traffic and MP with up to three E3s or T3s in each MP bundle.
•
Supports three operating modes that can be configured at the CLI: CPOS E3, CPOS T3, or
POS (155 Mbps).
•
The configuration of the operating mode can take effect only after you hot-plug the interface
module or reboot the device. It is recommended to remove and insert the module to bring the
configuration into effect.
•
Before removing a HIM interface module during device operation, execute the
remove
command for the module.
•
The configuration of the operating mode takes effect for all the interfaces on the interface
modules.
NOTE:
The HIM-CLS1P/HIM-CLS2P does not support channelizing OC-3/STM-1 into DS1s or E1s.
