  • (1888PressRelease) June 01, 2013 - Gaithersburg, Maryland, USA - Speaking to reporters, Mr. Vijay Kulkarni CEO of the company said, "E1 Multi-Frequency Compelled R2 (MFC-R2) signaling is a Channel Associated Signaling (CAS) protocol used over E1 signaling networks. "Compelled" is to convey that each digit transmission and cessation of transmission is controlled and acknowledged by the receiver of the digit. MFC-R2 is used to convey addressing information along a telephone trunk between two switches in order to establish a telephone call along that path."

    He added, "CAS MFC-R2 protocol 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 other telecom protocols.

    MAPS™ CAS MFC-R2 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 protocols. E1 MFC-R2 Signaling (all variants, full /semi compelled) Emulation as defined per the ITU Recommendations Q.421-Q.442 can be supported by extending the existing scripts."

    Mr. Kulkarni further added, "MAPS™ CAS Emulator can also support various CAS protocols such as E1 European Digital CAS (EUC), E1 Digital E & M, E1 International Wink Start, T1 Wink Start (R1 wink), T1 Loop Start, T1 Ground Start, T1 Feature Group D, T1 Immediate Start, and any user-defined CAS protocol. It 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."

    Important Features:

    ·Sends MFC-R2 forward and backward tones per CCITT specifications
    ·Mimics the compelled network
    ·Establishes calls manually or automatically
    ·Time-slot selectable
    ·Record communication exchanges to log file


    ·Determine addressing formats between exchanges
    ·Test & analyze MFC-R2 addressing formats
    ·Manually test MFC-R2 implementations
    ·Test forward capabilities using automated backward sequences
