Clarinet - ISDN Applications

Two Clarinet interface pods are available for ISDN applications:

Template profiles are provided as standard allowing easy configuration, in order to act as either a Network (NT), a Terminal (TE) or a passive monitor. Simulation profiles have been pre-configured to generate thirty two outgoing ISDN calls using the most common information element content. It is easy to copy and paste content between the calls, to select starting delay, duration, inter-call delay, number of calls, connected device, clearing cause value and all information element content.

The information element editor provides drop-down boxes for simple selection of the required content. If invalid contents are required, HEX coding may be used. Event filters allow full configuration of the detail on the user display. B channel contents may be recorded and converted to WAV files for comparison or optional quality measurement.

System Software

Customers may select to purchase our traditional Run-Time software or new Zumara software. New Zumara software includes the added advantage of support for the host PC NIC or external LAN adapters, for VoIP analysis & simulation.

Both software packages are fully compatible with Clarinet S/T-U & E1/T1 hardware interface pods. Any combination of up to seven E1/T1, S/T-U or LAN interfaces may be connected & controlled simultaneously.

For those customers focused on S/T-U or E1/T1 applications, who do not require Ethernet connectivity now or in the future, our Run-Time software may be preferred.
