GL Communications (News - Alert) Inc., a major player in providing PC-based test, analysis, simulation products and consulting services to the worldwide telecommunications industry, has introduced Channel Associated Signaling (CAS) Analysis and Emulation software.

“GL's CAS Analyzer supports real-time monitoring and decoding of CAS signaling events over T1 E1 networks. Supported standards include MFCR2 and R1 protocols. The Real-time CAS Analyzer requires GL's T1/E1 internal cards or USB T1 E1 external units, and corresponding software licenses and works on a Windows XP (or higher) Operating System,” said Jagdish Vadalia senior manager for product development of the company, in a statement.

Vadalia said that GL’s MAPS CAS Emulator is a client-side application that works along with GL’s T1 E1 Analyzer Cards and Windows Client/Server software. This test tool is used to perform testing using CAS signaling and transmission and detection of TDM traffic over T1 E1 using scripts, and offers a complete solution for testing, troubleshooting, and maintenance of devices and networks implementing CAS. MAPS CAS automates the testing procedure with ready scripts for inbound and outbound calls.

“Calls are established, once the signaling information such as signaling bits, DTMF/MF digits, or Tones are sent or detected,” said Vadalia.

TMCnet earlier this month reported that GL Communications has introduced the addition of Channel Associated Signaling (CS) Protocol Emulator to GL's Message Automation and Protocol Simulation (MAPS) platform.

MAPS is a protocol simulation and conformance test tool that supports protocols such as SIP, MEGACO, MGCP, SS7, ISDN, GSM, MAP, CAS, LTE (News - Alert), UMTS, SS7 SIGTRAN, ISDN SIGTRAN, SIP I, GSM AoIP, Diameter and many others.

In Channel Associated Signaling, a channel or timeslot carrying speech also carries the signaling and addressing to set up and tear down calls, according to Jagdish Vadalia. The supervisory signaling is carried as “onhook” or “offhook”. The addressing is carried as DTMF (Dual Tone Multi Frequency) or as MF (Multi Frequency).
