Trillium Digital Systems Inc. Announces Additional Functionality for ISDN Variant.LOS ANGELES--(BUSINESS WIRE)--Nov. 11, 1997--Trillium Digital Systems Inc., a leading provider of communications software solutions, today announces the release and shipment of the Q.SIG protocol variant with additional functionality for its Integrated Services Digital Network Integrated services digital network (ISDN) A generic term referring to the integration of communications services transported over digital facilities such as wire pairs, coaxial cables, optical fibers, microwave radio, and satellites. (ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. ) Q.930/Q.931 software product. The Q.SIG protocol is a Private Branch Exchange-to-Private Branch Exchange (PBX-to-PBX) communication standard. Trillium's newly released feature, known as Generic Functional Transport (GFT GFT Global Forex Trading (Global Futures & Forex, Ltd.) GFT Glasgow Film Theatre (Glasgow, Scotland) GFT Geographic Full-Time GFT General Flight Test (pilot licensing) ), enables a PBX to provide ISDN capabilities across public networks. It also broadens the bandwidth available on an existing ISDN link at no extra cost. Q.SIG also provides PBX users with various features such as call waiting, call transfer, do not disturb Do not disturb usually referes to a status where the subject prefers to be left in solitary. It can also mean the following:
Trillium Chief Technology Officer Larisa Chistyakov said, "Trillium is committed to providing computer and communications equipment manufacturers with up-to-date, standards-based protocols. Trillium originally had the Q.SIG variant providing signaling capabilities within a PBX. We added signaling support for the GFT protocol to enable our customers to transfer data transparently across separate PBX systems using a public ISDN network to support virtual private networks." PBX network interfaces have 30 B-channels and one D-channel. Normally, the B-channels carry data and the D-channel is used for signaling. GFT allows the D-channel in an ISDN link to carry data along with this signaling information. Trillium's latest Q.930/Q.931 software release with the additional Q.SIG GFT feature implements layer 3 procedures required for circuit-switched call control at the Q reference point for the control of supplementary services and additional network features. These procedures allow call-dependent, call-independent and connectionless services that can be used to establish virtual private networks. Trillium's Q.930/Q.931 Q.SIG variant implementation supports the following standards: International Standards Organization See ISO. (ISO (1) See ISO speed.
