Glossary:
local survivable processor (LSP)
A configuration of the S8300 Media Server that is used to provide redundancy in Avaya Communication Manager. In the
LSP configuration, the server acts as an alternate server or gatekeeper for IP entities such as IP telephones and Avaya
G700 Media Gateways. These IP entities use the LSP when the entities lose connectivity to the primary server. Also
called survivable cc.
logical link
The communications path between a processor and a Basic Rate Interface (BRI) terminal.
loop-start trunk
A trunk on which the system establishes a connection with a distant switching system for an outgoing call, and then waits
for a signal on the loop that is formed by the trunk leads. When the system receives that signal, the system sends the digits
of the called number.
LOS
Loss of signal
loss plan
An overall plan that is used in network design and network management to create and maintain consistent signal strength
across the network. The term also applies to the local management of signal strength to achieve appropriate levels for
specific applications.

main distribution frame (MDF)
A device that can be mounted to the wall inside the system equipment room. The MDF provides a connection point from
outside telephone lines to the switch and to the inside telephones.
main-satellite-tributary (MST)
A private network configuration that can either stand alone or access an electronic tandem network (ETN). A main switch
uses tie trunks to interconnect with one or more subtending switches or 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). Tie trunks connect a tributary switch to the
main switch, but the main switch has its own attendant positions and LDN. See also
(ETN)

maintenance
Activities to keep a telecommunications system in proper working condition. Maintenance activities include the detection
and the isolation of software faults and hardware faults, and automatic recovery and manual recovery from these faults.
