Overview

Channel Associated Signaling (CAS) is a method of signaling in telephone networks where each channel or timeslot carrying speech also carries with it the signaling and addressing to set up and tear down that same channel. This is referred to as "in-band" signaling. Various types of CAS signaling types include Loopstart, Groundstart, Feature Group D (FGD), Winkstart, E1 MFCR2, and others.

GL's Channel Associated Signaling (CAS) simulator is a client-side application that works along with the GL's T1/E1 Analyzer Cards and Windows Client/Server software. It is an optional application that simulates and analyzes any user-defined CAS protocols by providing signaling bit transitions and forward/backward frequency digits and tones. In order to easily create the user-defined CAS scripts, the CAS simulator includes a script editor. Multiple user-defined protocols may be defined for each of the digital T1/E1 trunks associated with the GL analysis boards. In addition to generating/receiving CAS calls, the CAS simulator also processes the receipt of Dialed Number Identification Service (DNIS) and Automatic Number Identification (ANI) information.

CAS emulation is also available with GL's Message Automation and Protocol Simulation (MAPS™). MAPS™ is a multi-protocol, multi-technology platform used for the emulation of a variety of communication protocols over IP, TDM, and Wireless networks. MAPS™ CAS can automate the testing procedure allowing the users to establish calls, and send/receive TDM traffic such as DTMF/MF digits, Tones, Fax, and Voice.

In addition, GL supports various E1 MFCR2 analysis and simulation solutions. For more information, visit MFC-R2 Analysis and Emulation webpage.

MFC-R2 Analysis and Emulation

GL's MFCR2 Analysis & Emulation solutions use any of the following hardware:

• T1E1 Analyzer (Potable USB or Ultra HD PCI cards or Universal Cards) Or
• DCOSS (Digital Central Office Switch Simulator)

Both the products supports remote capture & analysis using client-server technology, while DCOSS is ideal for simulating and testing advanced telecom networks and products, including switches, gateways, and transmission systems.

MAPS™ CAS Emulator

MAPS™ CAS Emulator automates the testing procedure allowing the users to establish calls, and send/receive TDM traffic such as DTMF/MF digits, Tones, Fax, and Voice.

Supports testing of various protocols such as T1 Wink Start (R1 wink), T1 Loop Start and T1 Ground Start, T1 Feature Group D, T1 Immediate Start, E1 MFC-R2 (All variants, full /semi compelled), E1 European Digital CAS (EUC), E1 Digital E & M, E1 International Wink Start, and Any User-Defined CAS Protocol.

E1 MFC-R2 Signaling defined by the ITU Recommendations Q.421-Q.442, uses a multi-frequency compelled signaling protocol to exchange address information. MAPS™ CAS Emulator generates and sends MFC-R2 forward and backward tones per CCITT specifications. Currently, MAPS™ CAS includes ready profiles for India, China, and Mexico. Different country specific implementations will be supported in future.
