The MIB for signalling Connection Control Part(SCCP)
messages transported over Signalling System
No. 7 (SS7) Network via Cisco IP Transfer
Point.

This MIB provides information specified
in ITU Q752 Monitoring and Measurements for
Signalling System No. 7(SS7) Network.

The Cisco IP Transfer Point (ITP) is a hardware
and software solution that transports SS7 traffic
using IP. Each ITP node provides function similar
to SS7 Signalling point.

The relevant ITU documents describing this technology
is the ITU Q series, including ITU Q.700: Introduction
to CCITT Signalling System No. 7 and ITU Q.701
Functional description of the message transfer part
(MTP) of Signalling System No. 7.

The IETF Working Group Signalling Transport (SIGTRAN)
has defined MTP3 User Adaptation (M3UA) and SCCP
User Adaptation (SUA) protocols. The drafts can be
found at:
http://www.ietf.org/html.charters/sigtran-charter.html
