CAS

Channel Associated Signaling is a digital signaling protocol for the set-up and tear-down of phone calls.

CAS and TelcoBridges

As of July 2009, CAS signaling is supported at the Basic API level but is not supported at the Toolpack / Web Portal level and is thus not accessible for more basic applications. TelcoBridges is investigating tbe possibility of exposing access to CAS at the web portal level or higher.

RBS T1 variants:

• Wink start
