5.4.2 MCPA Module Alarms
The set points, delay, reset points, and latching conditions of all three types of
alarms are software configurable. Some Minor alarm settings can be specified by
the customer but must be agreed upon between the customer and Spectrian prior to
installation or modification. Alarm limits for Major and Critical Alarms are fixed
and can not be modified, insuring long term reliability of the MCPA module.

5.4.3 MCPA System Alarms
A multi-module MCPA system will have an Amplifier Management Module
(AMM) that summarizes the status of all modules and reports this information to
the base transceiver station (BTS). The format of this information is usually
customized for specific customers. Options for physical layer customization
include:
(AMM) that summarizes the status of all modules and reports this information to
the base transceiver station (BTS). The format of this information is usually
customized for specific customers. Options for physical layer customization
include:
•
Parallel TTL Interface – Summary bits for individual module status.
•
Serial Interface (RS-232, RS-422) – Customized strings sent to BTS interface.
•
Form-C Relay Contacts – Wired directly into BTS.
The customer usually specifies messaging layer customization. In addition
Spectrian does maintain an internal standard for serial messaging. System status is
generally a combination of the module status. The customer also specifies this. An
example of a system alarm hierarchy might be as noted in the table below.
