SIGTRAN is the name, derived from signaling transport, of the former Internet Engineering Task Force (IETF) working group that produced specifications for a family of protocols that provide reliable datagram service and user layer adaptations for Signaling System 7 (SS7) and ISDN communications protocols.

The Internet Engineering Task Force (IETF) has defined the SIGTRAN protocol suite that implements levels 2, 3, and 4 protocols compatible with SS7.

It supports the same application and call management paradigms as SS7 but uses an Internet Protocol (IP) transport called Stream Control Transmission Protocol (SCTP), instead of TCP or UDP.

The IETF Signaling Transport (SIGTRAN) working group defined the protocol (number 132 ) in 2000, and the IETF Transport Area (TSVWG) working group maintains it. RFC 4960 defines the protocol.

RFC 2719 also defines the concept of a signaling gateway (SG), which converts Common Channel Signaling (CCS) messages from SS7 to SIGTRAN.

A SIGTRAN Signaling Gateway is a network component that performs packet level translation of signaling from common channel signaling (based upon SS7) to SIGTRAN signaling (based upon IP).

M3UA stands for MTP Level 3 (MTP3) User Adaptation Layer as defined by the IETF SIGTRAN working group in (which replaces and supersedes ).

The signalling link functional level may also be provided using the SIGTRAN protocol M2PA described in RFC 4165.

Implemented in a variety of network elements including softswitches, the SG function can provide significant value to existing common channel signaling networks, leveraging investments associated with SS7 and delivering the cost/performance values associated with IP transport.

Note here that Analogue (ATA), PSTN telephone devices can only be reached by a softswitch that has embedded SS7 or SIGTRAN cards, software in terms of signalling AND Trunking Gateway for Voice traffic IP/TDM, TDM/IP, TDM/TDM functions.

In the SIGTRAN suite of protocols, there are two primary methods of transporting SCCP applications across Internet Protocol networks: SCCP can be transported indirectly using the MTP level 3 User Adaptation protocol (M3UA), a protocol which provides support for users of MTP-3—including SCCP.

Standard SCPs in the telecom industry today are deployed using SS7, SIGTRAN or SIP technologies.

These MAP messages may be transported using "traditional" TDM based signalling, or over IP using SIGTRAN and an appropriate adaptation layer.

Their primary purpose is to unify networks that use various transports and signaling protocols – such as SS7, SIP, SIGTRAN, TDM, IP, etc. – into cohesive service environments.

The July 2010 acquisition of Mutina Technology S.p.A. expanded the company’s offerings to cover Mobile Broadband (MBB), Next Generation Networks (NGN), SS7/SIGTRAN Signaling, VoD/IPTV, and IP Core for telecom and enterprise networks.

Argela’a SCP uses the current billing infrastructure with low initial investment by providing flexible architecture for future capacity/protocol extension like converged billing system, etc. SCP provides network independency-seamless multi-network support SS7, SIGTRAN and IP protocol independency-seamless multi-protocol,multi-vendor stack support.

This means that, instead of the Global Title routing, lower level MTP routing will be used for this message from this point on. Equivalently, in a system using SS7 over IP (for example, SIGTRAN), the result from Global Title Translation may be to route to an IP server, though the exact details depend greatly on which variant of SS7 over IP is being used.

MAP is a Transaction Capabilities Application Part (TCAP) user, and as such can be transported using 'traditional' SS7 protocols or over IP using Transport Independent Signalling Connection Control Part (TI-SCCP); or using SIGTRAN.

Indeed, the most significant protocol defined by the SIGTRAN group is SCTP, which is used to carry PSTN signaling over IP. The SIGTRAN group was significantly influenced by telecommunications engineers intent on using the new protocols for adapting VoIP networks to the PSTN with special regard to signaling applications.
