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 commonly referred to as 'in-band' signaling as opposed to 'out-of-band' signaling, such as ISDN or SS7. Signaling bits associated with each voice channel carry 'on-hook' and 'off-hook' status and addressing information in the form of dual tone digits to direct the call to its destination.
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 works with GL's T1 E1 analyzer hardware and corresponding software licenses (XX600, XX610, XX620, XX630).
Channel Associated Signaling (CAS) simulator is an optional application that works along with the GL's T1/E1 Analyzer Cards and Windows Client/Server software that simulates and analyzes any user-defined CAS protocols.
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, Voice, and Fax. In addition, GL supports various E1 MFCR2 analysis and simulation solutions.
Main Features
Displays summary, detail, hex-dump, and statistics views.
Summary View displays captured timeslot, sub channel, frame#, device#, CAS signaling information like signaling bits, digits, type of digit, tone, frequency of tone, power of tone, on duration and off duration etc.
Detailed View displays decodes of a user-selected frames from the summary view.
Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/sec etc for the entire captured data.
Hex dump View displays the frame information in HEX and ASCII format.
Streams may be captured on the selected time slots (contiguous or non-contiguous) and on full bandwidth.
Supports filtering and search based on digits, type of digits, signals etc.
Exports Summary View information to a comma delimited file for subsequent import into a database or spreadsheet.
Capability to export detailed decode information to an ASCII file.
Status bar displaying information regarding running percent utilization, number of frames captured, CRC errors and frame errors etc.
Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields.
Supported Protocol
The supported protocol standards in CAS protocol analyzer is MFCR2 and R1.
