B-Link4

ISDN Simulator with 4 Basic Rate S/T ports

Product overview

The B-Link4 is our compact ISDN basic rate network simulator with four ports. It performs complete call handling procedures for accurate simulation, without the need for a Switch or PBX (Central Office). B-Link4 may be used with routers, video conferencing terminals, terminal adapters, PC applications or any ISDN basic rate terminal fitted with a standard S/T interface!

Because B-Link4 has 4 independent network ports, is can be used to enable the cross connection of 4 ISDN terminals using all 8 (64k) B channels simultaneously.

Convenience

B-Link4 allows you to make 64K or full bandwidth 128K data (or speech) calls in your CCIE lab, at an exhibition or on the work bench. It's even possible to make calls from one terminal in isolation, using the auto-answer mode. Status LED's are provided to indicate activity at all protocol layers including any bearer (B) channels used. Each B-Link4 is supplied with a simple delivered configuration with easy to remember telephone numbers for each port, allowing you to gain full control of your application within minutes.
