Description

Mitel’s MT90810 is a Flexible MVIP Interface Circuit (FMIC). The MVIP (Multi-Vendor Integration Protocol) compliant device provides a complete MVIP compliant interface between the MVIP Bus and a wide variety of processors, telephony interfaces and other circuits. A built-in digital time-slot switch provides MVIP enhanced switching between the full MVIP Bus and any combination of up to 128 full duplex local channels of 64kbps each. An 8 bit microprocessor port allows real-time control of switching and programming of device configuration.
