LBI-39224

Jessica PBX Gateway

Jessica Private Branch eXchange Gateway – This advanced telephone interconnect system is used with CEC/IMC equipment to provide EDACS radio system users access to local public switched telephone networks (PSTN). Jessica incorporates the Ericsson MD110 PBX. It is interfaced to the CEC/IMC via a PIM. (Also see

PIM.)

LRIM

Logging Recorder Interface Module – This CEC/IMC interface module provides audio outputs for logging recorders. Each output channel can be programmed to supply audio based on groups or individual units within the CEC/IMC network.

message trunked call

A message trunked call is a call which is assigned a working channel for the duration of the entire communication process, not just a single PTT sequence. This accomplished by adding hang-time after each PTT. Emergency and telephone interconnect calls operate in a message trunked mode. (Also see transmission trunked call.)

MIM

MASTR II/III Interface Module – The MIM connects an EDACS radio system to the CEC/IMC switch. EDACS radio systems include EDACS sites, simulcast systems, CNI systems, and SCAT systems.

modem data

Modem data includes any system control, digital voice, or user data transferred via modem equipment using modulated/demodulated signals. For example, the uplink/downlink control data transferred between the CEC/IMC location and an EDACS trunked site is modem (control) data.

MOM

MOnitor Module – The MOM is a CEC/IMC interf ace module that provides serial data connections for the CEC/IMC Manager (MOM PC) and the System Manager computers. It also provides many important functions for the CEC/IMC and it stores certain databases for the CEC/IMC such as the current ("soft" or console) patch/simulselect settings made from consoles.

multisite

A multisite is a network of multiple EDACS radio systems and possibly conventional radio systems all linked together for wide-area communication. In a multisite network adjacent systems do not use the same radio frequencies.
