GL Communications Inc. announced today the release of its latest product INAP Emulation over IP.


MAPS™ ANSI INAP is an advanced protocol simulator/tester for ANSI INAP (Intelligent Network Application Part) services. It is able to run pre-defined test scenarios against ANSI INAP test objects in a controlled & deterministic manner.

GL Communications Inc. announced today the release of its latest product INAP Emulation over IP.

Speaking to reporters, Mr. Jagdish Vadalia Senior Manager for product development of the company said, “INAP is part of SS7 protocol suite and used for services such as single number translation (800), local number portability, incoming call management (do not disturb or call forwarding), backup call destinations in case of disaster, and similar services.”

He added, “MAPS™ ANSI INAP is an advanced protocol simulator/tester for ANSI INAP (Intelligent Network Application Part) services. The tester supports testing network elements gsmSCF and gsmSSF, error tracking, regression testing, conformance testing, and load testing/call generation. It is able to run pre-defined test scenarios against ANSI INAP test objects in a controlled & deterministic manner.”

Mr. Vadalia further added, “MAPS™ ANSI INAP scripts are suitable for testing objects accurately, reliably and validated for compliance with ANSI specifications. It is suitable for controlling telecommunication services such as CNAM (Calling Name Delivery), LNP (Local Number Portability), and Toll-free 800 Number over TCAP layer."

"The MAPS™ ANSI INAP application gives the users the unlimited ability to edit ANSI INAP messages and IN service scenarios (message sequences). "Message sequences" are generated through scripts. "Messages" are created using message templates.”

Main Features:

  • ANSI INAP Emulator can simulate GSM SSF and GSM SCF entities
  • User-friendly GUI for configuring the SCTP Layer
  • User configurable signaling links
  • Access to all ANSI INAP message parameters like CNAM, TCAP 800 Number, LNP, Signaling .Link Test Message, and more
  • User controlled access to optional parameters such as timers
  • Ready scripts for Customizable 800 Number, CNAM, LNP, Call Diversion
  • Supports customization of call flows and message templates using Script editor and Message editor
  • Supports scripted call generation and automated call reception
  • Provides protocol trace with full message decoding, and graphical ladder diagrams of call flow with time stamp
  • Script based & protocol independent software architecture
  • Provides call statistics with associated captured events and error events during call simulation

About GL Communications Inc.,
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.

GL’s TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax.  Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC,  and many more. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.

GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.

GL’s Echo Canceller testing solutions provide the broadest range of simulation and analysis, including line and acoustic echo. GL’s compliance testing per G.168. G.167, and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

GL’s wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.

GL’s Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.

GL’s Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network characteristics.  Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
