Comrex Matrix - POTS/ISDN Protable + Rackmount Interface Bundle - Used

This used Comrex Matrix provides both ISDN and PSTN full duplex links of 15kHz, and interfaces to the cellular network to provide enhanced audio quality via a mobile phone connection. Fully compatible with all modes of the Vector and HotLine PSTN codecs, the Matrix provides a two-channel audio input mixer with additional tape input, comprehensive call handling and automatic interfacing to Matrix, Vector and HotLine codecs.

The Matrix accepts a plug-in ISDN module that provides three options for getting audio to and from a remote location via ISDN: Industry-standard G.722 on a single bearer; ISO/MPEG Layer III 15kHz bandwidth audio (also on a single bearer); and Comrex Turbo G.722 on two bearers, giving 15kHz full duplex audio with just a 6ms delay.

The Matrix can either connect directly to a suitable cellular telephone but also accepts a plug-in interface for a PCMCIA modem for a GSM mobile phone, over which it can send and receive surprisingly good audio quality via the cellular phone network. Being a plug-in module, the Matrix will be able to take advantage of new developments in cellular services as and when they become available, preserving the value of your investment.
