MAPS™ Automated Analog Terminal (FXO) and Network Port (FXS) Testing -- PTE015-Image

FXS and FXO are ports used by analog phone lines or phones. A Foreign Exchange Subscriber (FXS) port supplies ring voltage, battery current, dial tone and voice signals. Foreign Exchange Office (FXO) delivers an on-hook/off-hook indication (loop closure), DTMF digits, voice signals, and is usually a phone or fax machine.
The FXO and FXS ports on tProbe™ unit allows to simulate all of the above features. Also, the FXO port on the tProbe™ permits non-intrusive capture and analysis of voice-band signals from a two-wire telephone line. The FXS port on tProbe™ emulates a two-wire FXS service such as a telephone wall jack.
GL's Message Automation & Protocol Simulation (MAPS™) platform is a general purpose protocol emulator tool for various protocols encountered in the telecom space. GL's MAPS™ FXO FXS is one such advanced test tool that supports emulation of functions of Foreign Exchange Subscriber (FXS) by analog phone lines and Foreign Exchange Office (FXO) by phones using the FXO and FXS ports on a tProbe™ unit. MAPS™ provides a facility to place call/answer incoming call on both FXO and FXS ports and automate the entire testing process using scripts.
MAPS™ FXO FXS Emulator includes features to handle different types of traffic like tones, digits (DTMF, MF, MFR2F, MFR2B), voice files, fax, and more. Data width of the traffic being sent/ received over the FXO/FXS ports can be extended up to 16 bits to improve signal to noise performance. Also, GL’s MAPS™ FXO FXS application can be used to simulate CAMA trunks connected to the 911 selective router (SR) and can be configured for non-intrusive monitoring of 911 services. CAMA simulation capabilities include - seize the line, wait for wink, dial ANI, wait for call connect, detect seizure from far side, provide wink, wait for ANI, and connect the call. CAMA monitoring capabilities include - seizure and wink start detection, onhook and offhook detection and MF digit (ANI) detection.

Digital Signal Formats

FXO/FXS supports following digital signal formats:

  • A-Law: This is the 8-bit codebook format typically used in E1 systems.
  • µ-Law: This is the 8-bit codebook format typically used in T1 systems.
  • 16-bit Linear: This is a 16-bit linear signal. Intel ("little-endian") byte ordering is used. (Currently this feature is supported only by FXO).
Applications

  • Testing (simulation, and monitoring) 911, E-911, and NG-911 systems
  • Testing gateways, VoIP ATAs, telephone lines, handsets, VoIP PBX.
  • Voice quality testing, 2wire call automation, Caller ID.
  • Monitoring signaling, voice, and tones on telephone lines non-intrusively.
  • Generation and reception of traffic on 2-wire telephone lines.
  • Provides fault insertion, and erroneous call flows testing capability.
  • Ready scripts make testing procedure simpler, less time consuming and hence time to market products
  • Remote operation of FXO FXS ports over TCP/IP
