Communication Interface Module
optical signal to a specific International Telecommunication Union
When the CLIP module receives the optical signal from the DWDM side of the ONS 15200 network, the CLIP module converts the selected optical signal to the 1310 nm wavelength region and delivers it to the client layer. If the ONS 15200 system is optically protected (that is, the optical signal is carried on two routes), the CLIP module selects which optical signal to transfer to the client layer. You can install a CLIP module in either the ONS 15252 Multichannel Unit (MCU) or the ONS 15201
When the CLIP modules are not installed, attach front covers for electromagnetic compatibility and electromagnetic interference (EMC/EMI) precautions.
Release 1.1 provides a new CLIP module that incorporates both clocked (3R) and unclocked (2R) data regeneration. You can set the mode of operation (2R or 3R) using the management interfaces. The new 2R/3R CLIP is fully compatible with the existing 3R CLIP. The 2R/3R CLIP is user configurable for unprotected or fiber protected operation.
In addition, Release 1.1 provides two dispersion tolerances: 1800 ps/nm at 0 and 7 dBm, and 3000 ps/nm at 0 dBm.
Restrictions exist for CLIP replacement based on whether you are using a plenum or a fan unit in the ONS 15252 MCU. Table
Note CLIP replacement restrictions are related to mean time between failure (MTBF) performance and not

5.3 Communication Interface Module
The CIM allows you to extend the ONS 15252 MCU internal controller area network (CAN) bus to another ONS 15252 MCU or to an ONS 15201 SCU. Extending the CAN bus allows you to configure several network elements (NEs) into a larger functional unit. The CIM also provides the local craft interface to the Maintenance Manager software package, and the Electronic Industry Association/Telecommunication Industry Association (EIA/TIA)
