Press Release: GL Announces Channel Associated Signaling (CAS) Protocol Emulator

Gaithersburg, Maryland, USA - January 07, 2013 - GL Communications Inc. announced today the release of its latest product Channel Associated Signaling (CAS) Protocol Emulator.

Speaking to reporters, Mr. Jagdish Vadalia Senior Manager for product development said, "Channel Associated Signaling (CAS)" is a method of signaling where a channel or timeslot carrying speech also carries with it the signaling and addressing to set up and tear down calls.  The supervisory signaling is carried as "onhook" or "offhook".  The addressing is carried as DTMF (Dual Tone Multi Frequency) or as MF (Multi Frequency). This form of signaling is still used to route calls on the public switched telephone network (PSTN) including subscriber lines like 2wire local loops, on trunks between central offices (CO), and on access trunks such as PBXs. Typical CAS signaling methods are:  Loop Start, Wink Start, R1, MFC-R2, SS5, and other variants of these methods."

He added, "CAS emulation has been added to GL's Message Automation and Protocol Simulation (MAPS™) platform. MAPS™ is a protocol simulation and conformance test tool that supports a variety of protocols such as SIP, MEGACO, MGCP, SS7, ISDN, GSM, MAP, CAS, LTE, UMTS, SS7 SIGTRAN, ISDN SIGTRAN, SIP I, GSM AoIP, Diameter and many others.

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 Emulator 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."

Mr.Vadalia further added, "MAPS™ CAS Emulator supports powerful utilities like Profile Editor and Script Editor, which allow new scenarios to be created or existing scenarios to be modified for CAS Signaling. The test configuration window allows users to configure various CAS signaling types including R1 digit parameters, flow control parameters, forward/ backward tone parameters and various others to transmit and receive CAS inbound and outbound signals. MAPS™ also supports a Command Line Interface (CLI) such as the Python, TCL (Tool Command Language) scripting tools, to provide the capability of remote operation, automation, and multi-site connectivity."

Main Features:

  • Automated CAS signaling simulation over TDM (E1 T1)
  • Multiple T1 E1 line interfaces supported
  • Accesses the T1 (or E1) analyzer remotely
  • Supports ANI and DID identification
  • Customized signaling for each channel through scripts
  • Supports generation and detection of TDM traffic, including voice, fax, digits, and tones, over CAS signaling network
  • Supports scripting through a Command Line Interface (CLI) such as the Python, and TCL, using MAPS™ client-server functionality (requires additional license)
  • Supports customization of inbound and outbound calls using Profile editor and Script editor
  • Ready-to-use scripts for quick testing
  • Script based & protocol independent software architecture
  • Provides call reports with associated captured events and error events during call simulation
  • Option to send reports to database accessible via web interface
  • Supported on Windows® 7/8 or higher version operating systems.
