RFL NCM
Network Communications Module
DESCRIPTION
The Network Communications Module (NCM) is an Asynchronous Data Module designed for use in
RFL IMUX 2000 T1 and E1 multiplexers. It provides one DCE Half/Full-Duplex channel between an
unlimited number of locations using a single 64 kbps DS0 time slot. The NCM provides a fast and
reliable NMS communication path between nodes of a T1 or E1 network, and can also be used for
party-line applications such as DNP and Modbus networking.

The NCM is remote-controllable when installed in an RFL remote controllable shelf. The following
module parameters can be configured remotely via NMS or locally via DIP switches. A DIP switch
setting selects whether the card is in remote or local mode.
