Overview:
Signaling bits associated with voice channels carry routing information to direct the data to its destination. Channel Associated Signaling (CAS) is a
method of signaling each channel or timeslot. This is referred to as "in-band" signaling. Various types of CAS signaling methods include Loopstart ,
Groundstart , FGD and Winkstart along with E1 MFCR2.

GL's CAS simulator is a client-side application that works along with the GL's T1/E1 Analyzer. It can simulate and
analyze 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. This tool
allows easy point and click operation for building simple as well as complex CAS scripts.
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.
Supported Protocols:
- E1 MFC-R2 (All variants, fully/semi compelled)
- T1 Winkstart (R1 wink)
- T1 Loopstart and T1 Groundstart
- E1 European Digital CAS (EUC)
- Any User-Defined CAS Protocol
Main Features:
- Accesses the T1 (or E1) analyzer remotely
- Supports called number and calling number identification
- Customized signaling for each channel through scripts
Call Generation/Reception with Signaling Status
In addition to receiving and placing calls, CAS Simulator also processes the receipt of Dialed Number Identification
Service (DNIS) and automatic number identification (ANI) information, which is used to support authentication and other
functions. The screenshots to the right display the manual call generation, and number identification functions performed
by GL's CAS Simulator.
Script Editor
The GL CAS Simulator script is based on a self-describable language that can define the behavior of CAS Call Control
procedure. Functions such as Place Call, Answer Call, Incoming Call, Disconnect call are all defined within the script.
Additionally more advanced script may also be defined in the script. Definitions for Signalling Bit Transitions and
forward/backward digits/tones are user definable within each script.
Capture Events
The events screen chronologically lists all of the CAS State Machine signaling bit transitions generated by each timeslot
of each trunks.These transitions can be directed to an ASCII file is real-time or after they have appeared in the events
list.
Flash Hook
The application also provides a way for the users to send a Flash Hook signal in line manually. Users can vary Flash
Hook On Signal (0-F), Flash Hook Off Signal (0-F) and Flash Hook Interval (ms) for a given timeslot.
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. Click here to learn more.
Buyer's Guide:
Please Note: The XX in the Item No. refers to the hardware platform, listed at the bottom of the
Buyer's Guide, which the software will be running on. Therefore, XX can either be HDT, HDE, PCT, PCE, and UTE,
depending upon the hardware.
