Bearer Independent Call Control (BICC) Protocol Emulator

Gaithersburg, Maryland, USA – January 15, 2013- GL Communications Inc announced today its latest product MAPS™ BICC IP Emulator - Scripted Bearer Independent Call Control Protocol Emulation over IP.

MAPS™  BICC IP Emulator

Speaking to reporters, Mr. Karthik Ramalingam, Manager Product Development of the company said, “The Bearer-Independent Call Control (BICC) is a signaling protocol based on ISUP that is used for supporting narrowband ISDN service over a broadband backbone network without interfering with interfaces to the existing network and end-to-end services.  Specified by the ITU-T in recommendation Q.1901, BICC was designed to be compatible with existing networks and for that matter with any system that is  capable of carrying voice messages.”

He added, “MAPS™ BICC IP Emulator is used to emulate all the BICC interfaces over both TDM and IP. It is designed to specifically emulate BICC call control signaling as defined by ITU-T standards between Mobile Switching Center (MSC) and Gateway MSC (GMSC) server nodes. 

MAPS™ BICC IP Emulator can run pre-defined test scenarios against test objects in a controlled & deterministic manner. In addition, it also supports error tracking, regression testing, conformance testing, load testing, and call generation. It supports powerful utilities like Message Editor, Script Editor, and Profile Editor which allow new scenarios to be created or existing scenarios to be modified using BICC IP call control messages and parameters.”

Mr. Ramalingam further added, “GL’s MAPSBICC IP Emulator currently supports the following procedures emulating MSC (VLR), and GMSC entities in the network- Successful Basic Call procedure with enBloc and Overlap operation, Setup procedures, Mid Call Procedures, Normal Call Release Procedures, Unsuccessful call Setup, Codec modification/mid-call Codec negotiation procedures.”
