Newsletter: GL Releases Scripted & GUI ISDN Emulator
Welcome to another March 2009 issue of GL's Newsletter providing information and insight into our
Scripted ISDN Emulator and GUI ISDN Emulator products.
These products allow both manual and automatic testing of ISDN networks and equipment.
GL's ISDN Emulator for T1 E1 networks has been available as a manual GUI based ISDN Emulator and now
is available as a Scripted (client-server) based application.
ISDN emulation features include selection of various ISDN standards, variants & NFAS, including the flexibility to modify ISDN call parameters & message
content. This flexibility ensures that the ISDN emulator will communicate with a wide variety of systems under test. It's even possible to emulate a complete
ISDN connection (switch to subscriber) all in the same PC with a dual interface T1 E1 card.
Scripted ISDN Emulator
The scripted (client-server) based ISDN Emulator emulates ISDN calls over T1 E1 links in a similar manner as the GUI, with the added capability to script
entire ISDN sessions. The script can be run and rerun for automated environments.
Additionally, the ISDN Emulator application offers the following advantages:
- Simultaneous testing of high capacity T1 E1 systems through a single client
- Remotely control ISDN emulation using simple commands by client applications
- Collection of call records from remote locations
