GL Communication, a company offering test, monitoring and analysis equipment for TDM, Wireless, IP and VoIP networks, has announced that its ISDN Protocol Analysis and Emulation software are now available.

The company has released the new Integrated Services Digital Network (ISDN) software to simultaneously allow the transmission of voice, data and video worldwide using end-to-end digital connectivity.

ISDN, based on the telephony network, was conceived of to provide multiple voice and non-voice services over a single network and a digital user network interface over regular phone lines, instead of dedicated and isolated user-network interfaces.

Jagdish Vadalia, senior manager for Product Development at the company, said, “GL’s ISDN analyzer can capture and analyze stream of frames on an ISDN PRI link. It decodes LAPD according to Q.921, while, the ISDN information parsing is done based on the user's selection of ITU Q.931, ISDN ANSI, AT&T/Lucent switch 4ESS and 5ESS (TR41449, TR41459 and 235-900-342), Nortel's (News - Alert) switch DMS-100 and DMS-250 (NIS-A2111-1 and NIS-A211-4), Bellcore National ISDN-2 (NI-2), Euro ISDN (ETS-300 102-1), ARINC 746, ETSI 300-102, QSIG ETSI/ECMA, National ISDN PRI CPE, DPNSS, and DASS2.”

The newly released GL's ISDN Emulator is suitable for testing, troubleshooting, installation and maintenance of devices and networks implementing PRI ISDN. It is also useful to test ISDN products designed for either U or S/T interface, including network terminations, Type 1 terminating equipment, and terminal adapters.

ISDN equipment includes telephones, switchboards, PBXs, PC cards, Video Conferencing Equipment, Interconnect Systems, switches and routers.

Vadalia added, “GL's ISDN Emulator offers a complete solution for testing, troubleshooting, installation and maintenance of devices and networks implementing PRI ISDN. It is useful to test ISDN products designed for either U or S/T interface, including network terminations, Type 1 terminating equipment, and terminal adapters. ISDN equipment includes telephones, switchboards, PBXs, PC cards, Video Conferencing Equipment, Interconnect Systems, switches and routers.”

GL’s TDM Analysis & Emulation suite of products include the T1, E1, T3, E3, OC-3, OC-12, STM-1, STM-4, analog four-wire, analog two-wire interface cards and external portable pods.
