Signaling protocols: Difference between revisions

Revision as of 11:50, 2 April 2015

Signaling refers to the system of messages required to set up and tear down telephone calls between the calling and the called parties.

TelcoBridges provides support for the following signaling protocols:

PSTN
- SS7/C7
  - (20+ variants) MTP2, MTP3 and ISUP
- ISDN PRI
  - (14+ variants), National ISDN-2, Euro ISDN, DMS100, DMS250, 4ESS, 5ESS, Japan INS-NET1500, NET5 (France, Germany, UK, China, Hong Kong, Korea), NTT
- CAS (Script-oriented approach):
  - CASR1:
    - E&M "Wink start" or "Delay start"
    - Loop start (network side and user side)
    - ground start
  - CASR2:
    - Generic (ITU base specification)
    - Brazil
    - Mexico
    - Venezuela

IP
- SIP RFC 3261 User Agent, SIP Authentication
- SIGTRAN
  - M2UA, M2PA, M3UA and IUA

TelcoBridges Tmedia devices also offer the conversion (transcoding) of signaling messages between nodes that use different signaling protocols. For more information about Transcoding options, see TelcoBridges website.
All supported protocols can be used simultaneously.
