TelcoBridges' implementation of SIGTRAN is based on the concept of SS7 relay and termination.

The relay concept is where the SS7 signaling received from MTP2 links is forwarded directly to SIGTRAN peer(s).

SIGTRAN is used to RELAY SS7 signaling to the peer using either M2UA or M3UA-SG, without local processing of SS7 messages.


A termination corresponds to a link between two unique end-points. An example is provided below.

The SIGTRAN termination is used to receive SS7 signaling on the gateway for local processing (ISUP,SCCP,MTP3 routing).


Other details

  • The SIGTRAN Relay software license enables up to 64 M2UA links, 20 M3UA-SG links and 64 IUA links. (SS7 links must be purchased separately)
  • The SIGTRAN Termination software license enables up to 64 M2PA links and 20 M3UA-IPSP links.
