Chapter 1 Product Overview

Communication Channels

Each WCM has fiber-optic cables attached to its front panel. The remote lines of each WCM are connected to the MUX and DMX of the chassis. The common input and output connections of MUXs and DMXs (M1 to M4/D1 to D4) are connected to the BSM (M1 to M4/D1 to D4) in extension chassis A. For more information on the MUX/DMX modules, see the “Multiplexer and Demultiplexer Modules” section on page 1-22. The common input or output of the BSM (MUX/DMX) can be connected to the RSM receiver or transmitter (MUX/DMX) connector. The signals of the remote link are then present at the line A and line B connectors of the RSM.

16-Channel WCM System

A 16 channel WCM system consists of two chassis. Chassis 1 includes the NEMI module and chassis 2 holds the DEMI module. Both NEMI and DEMI have to be interconnected using an external bus cable to allow management and configuration control information to pass between the two chassis. The NEMI is configurable by the customer. For more details, refer to the Cisco Metro 1500 Series Software Configuration Guide.

32-Channel WCM System

NEMIs exchange their data over a connection and the two originally independent 16 channel WCM systems appear to the outside as a single 32-channel WCM system. When two 16-channel units are connected in this manner, the NEMI in chassis 1 is configured to be a NEMI-master and the NEMI in chassis 3 is configured to be a NEMI-slave. Both NEMIs are connected through their Ethernet ports to the Ethernet hub. For more details, refer to the Cisco Metro 1500 Series Software Configuration Guide.

128-Channel ESCON System

The first NEMI, installed in chassis 1, is configured to be a NEMI-master and the other three NEMIs are all configured as NEMI-slaves. All four NEMIs are connected through their Ethernet ports to the Ethernet hub. Provided that the frames are connected and configured as described, the complete system of eight
