Signaling Gateway
A network element that
receives/sends SCN native signaling
at the edge of the IP network. The
SG function may relay, translate or
terminate SS7 signaling in an
SS7-Internet Gateway. The SG
function may also be coresident with
the MG function to process SCN
signaling associated with line or
trunk terminations controlled by the
MG (e.g., signaling backhaul). A
Signaling Gateway could be
modeled as one or more Signaling
Gateway Processes, which are
located at the border of the SS7 and
IP networks. Where an SG contains
more than one SGP, the SG is a
logical entity and the contained SGPs
are assumed to be coordinated into
a single management view to the SS7
network and to the supported
Application Servers.
Signaling Gateway Process
A process instance of a Signaling
Gateway. It serves as an active,
backup, load-sharing, or broadcast
process of a Signaling Gateway [RFC
4666].
Service Information Field
MTP Service Information Field is
the payload field of an SS7 MSU
header. The first byte of the SIF is
the start of the MTP3 routing label.
For MTP3-variant networks, the
maximum SIF size is 272 bytes. For
