SS7 Tunneling
SS7 Tunneling doesn’t apply to the V6100.
The Signaling System 7 (SS7) tunneling feature facilitates peer-to-peer transport of SS7 links
between gateways that support 3Com' unique MTP2 (Message Transfer Part) Tunneling
application (M2TN) for transferring SS7 MTP2 link data over IP. In this scenario, both sides
of the link are pure TDM switches and are unaware of the IP tandem that is utilized between
them. Using M2TN, the network operator can support SS7 connections over IP, carrying
MTP level 3, as well as higher level SS7 layers (e.g., user parts and application protocols,
such as TUP (Telephone User Part), Integrated ISUP (Services User Part), SCCP (Signaling
Connection Control Part), TCAP (Transaction Capabilities Application Part)).
M2TN uses standard protocols, such as SIGTRAN (RFC 2719 Architectural Framework for
Signaling Transport), SCTP (RFC 2960, Stream Control Transmission Protocol), M2UA
(RFC 3331, MTP2 User Adaptation Layer), the latter being used for transporting SS7-MTP2
signaling information over IP. M2UA architecture is shown in
Figure 105 . M2TN architecture
is shown in Figure 106 .
