#Alcatel_Business_Communications #ABC is a proprietary communications protocol written by Alcatel-Lucent that is based on QSIG. Note.1*

ABC is supported over a variety of network types: IP, ATM, frame relay, PSTN, ISDN, or leased line.

The ABC protocol is based on four modules and offers the following services:

ABC-F: Telephone Features. Provides telephone feature transparency; features available in a single system are available across the entire network.

ABC-A: Applications. Offers network-wide applications as both centralized and distributed solutions.

ABC-R: Routing. An adaptive routing mechanism that optimizes the size of network links and improves security. Designed to use: least-cost routing, automatic route selection, forced on-net, break-in, break-out, and link optimization on transfer.

ABC-M: Management. Guarantees consistency of databases among all Alcatel OmniPCXs. It is used to inform the whole network about configuration changes and provides centralized alarms.

Note.1:
QSIG is an ISDN based signaling protocol for signaling between private branch exchanges (PBXs) in a private integrated services network (PISN). It makes use of the connection-level Q.931 protocol and the application-level ROSE protocol. ISDN "proper" functions as the physical link layer.
