link peripheral processor (LPP)
The DMS SuperNode equipment frame for DMS-STP that contains two
types of peripheral modules: a LIM and an LIU. For DMS-STP
applications, CCS7 link interface units 7 (LIU7) are used in the LPP.
LIU
See link interface unit.
LM
See line module.
LPP
See link peripheral processor.
message transfer part (MTP)
Provides a connectionless transport system for carrying CCS6, CCIS6, and
CCS7 signaling messages between user locations or applications functions.
MTP is a CCITT N7 protocol.
MTP
See message transfer part.
OM
See operational measurement.
operational measurement (OM)
The hardware and software resources of the DMS-100 Family systems that
control the collection and display of measurements taken on an operating
system. The OM subsystem organizes the measurement data and manages
its transfer to displays and records. The OM data is used as a basis for
maintenance, traffic, accounting, and provisioning decisions.
peripheral module (PM)
A generic term referring to all hardware modules of DMS-100 Family
systems that provide interfaces with external line, trunk, or service facilities.
A PM contains peripheral processors, which perform local routines, thus
relieving the load on the central processing unit.
PM
See peripheral module.
SCCP
See signaling connection control part.
