is provided with two LEDs, which indicate the port running status and fault detection status,
respectively. The HIM-CL2P provides two SFP ports.
The HIM-CL1P/HIM-CL2P has the following features:
•
Connects to the processor through a 10-Gbps high-speed bus. Each CPOS interface can be
channelized into 63 E1s or 84 T1s, and it can be channelized into 512 DS0s.
•
Receives multiplexed E1/T1 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 the Multi-link Point-to-Point Protocol (MP), and supports up to
12 E1s or T1s in each MP bundle.
•
Uses hardware-based MP bundling. This solves the problem of low efficiency of MP bundling,
and improving the access density of user devices.
•
Supports two operating modes that can be configured at the CLI: CPOS E1 and CPOS T1.
•
The operating mode configuration takes effect only after you hot-swap the interface module or
reboot the device. As a best practice, 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 operating mode configuration takes effect for all the interfaces on the interface module.
NOTE:
•
The HIM-CL1P/HIM-CL2P does not support cascading and non-channelized SDH and SONET.
•
The HIM-CL1P/HIM-CL2P does not support channelizing OC-3/STM-1 into DS3s or E3s.
