main-satellite-tributary
A private network configuration that can either stand alone or access an ETN. A main switch provides inter-
connection, via tie trunks, with one or more subtending switches, called satellites; all attendant positions for 
the main/satellite configuration; and access to and from the public network. To a user outside the complex, a 
main/satellite configuration appears as one switch, with one listed directory number (LDN). A tributary 
switch is connected to the main switch via tie trunks, but has its own attendant positions and LDN.
maintenance
Activities involved in keeping a telecommunications system in proper working condition: the detection and 
isolation of software and hardware faults, and automatic and manual recovery from these faults.
management terminal
The terminal that is used by the system administrator to administer the switch. The terminal may also be used 
to access the BCMS feature.
major alarm
An indication of a failure that has caused critical degradation of service and requires immediate attention. 
Major alarms are automatically displayed on LEDs on the attendant console and maintenance or alarming cir-
cuit pack, logged to the alarm log, and reported to a remote maintenance facility, if applicable.
Manual-In work mode
One of four agent work modes: the mode in which an agent is ready to process another call manually. See 
Auto-In Work mode
 for a contrast.
