MAPS™ CAS Protocol Simulation

MAPS™ CAS architecture

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 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.

Supported CAS Protocols includes -

  • T1 Wink Start (R1 wink)
  • T1 Loop Start and T1 Ground Start
  • T1 Feature Group D (FGD)
  • T1 Immediate Start
  • T1 CAMA (Centralized Automated Message Accounting)
  • E1 MFC-R2 (All variants, full /semi compelled)
  • E1 European Digital CAS (EUC)
  • E1 Digital E & M
  • E1 International Wink Start
  • E1 Sweden P7
  • Any User-Defined CAS Protocol

Supported Analog Legacy Protocols Simulation

  • Single Frequency (SF) Signaling
  • Voice Call Signaling
  • SS1/SS4 Signaling
  • SS5 Signaling
  • Analog MFCR2

Real-time & Remote SS1/SS4 Emulator and Analyzer

SS1 Analyzer

Selective Signaling "SS-1" is a 2 and/or 3 digit dial system used by the Federal Aviation Administration "FAA" within their National Airspace System "NAS" Ground-to-Ground Air Traffic Control Network. It is used on leased and FAA lines between the Air Route Traffic Control Center's "ARTCC", Terminal Radar Approach Control "TRACON", Air Traffic Control Tower's "ATCT", Lockheed Martin Flight Service Hub's "FS-21", Military, National Weather Service and nongovernmental aviation facilities for the control and management of aircraft flights.

GL's SS1 Analyzer detects and analyzes tone sequences that make up SS1 dial digits. Sequences of pulse and guard tones are detected, decoded, and assembled into their corresponding dial digits. The tone sequences are also verified for compliance against a "specification" parameter file. The SS1 Emulator (Dialer) application provides the ability to setup and dial tone sequences that make up SS1 dial digits.

MAPS™ Analog Phone Simulator (APS)

MAPS™ APS Network Diagram

MAPS™ APS is the high capacity Analog 2-wire Bulk Call Generator used to test a Central Office (CO), PBX, ATAs, Gateway or other telecommunications equipment, which provide local loop interfaces. It includes a compact system comprising of MAPS™ APS, Analog Interfaces, Patch Panels and other optional modules (Fax Emulation and VQT Analysis) in a rackmount system.  MAPS™ APS system supports up to 96 independent FXO ports per 1U MAPS™ APS Server and APSCB-48. More can be achieved by simply scaling the system with a 4U MAPS™ APS Server sporting 2 Octal T1E1 Cards which can then support up to 384 analog ports.
