TTC Q931-a Protocols

The TTC defined private networking ISDN protocol is largely based upon ITU-T

Q.931 protocol. DEFINITY ECS supports the following TTC defined protocols:

Basic Call support as defined in JT-Q931-a “Digital Interface between PBXs (Common Channel Signaling) — Layer 3”

Number Identification Services as defined in JT-Q951-a “Digital Interface between

PBXs (Supplementary Services) — Number Identification Services”

Differences from ITU-T Q.931 include:

•symmetrical operation as Peers similar to QSIG protocol, i.e. No Network/User definition

•different protocol discriminator

•Progress Indicator IE not supported in DISCONNECT messages

•Timers T310 and T313 are disabled

•Sending Complete IE not supported

•NOTIFY messages are not supported.
