- MITEL's MB89110/120 boards provide a primary rate-compatible communications
- interface for PC-based equipment. The MB89110 Dual T1 Card contains two T1
- 1.544 Mbps interfaces; the MB89120 Dual E1 Card contains two CEPT 2.048 Mbps
- interfaces. Both boards include an analog handset interface to record messages
- or monitor traffic. HDLC resources provide common channel and/or Facility Data
- Link (FDL) signalling support, and a digital PLC provides timing generation.
- The cards include a 512-channel Enhanced Compliant MVIP switch matrix to
- provide time-switching within the cards, as well as for the 256-channel MVIP
- bus. The matrix allows the MB89110/120 to act as a central
- communications/switching resource in an MVIP system. UNIX device drivers and an
- API are available for the boards: MS7141 for the MB89110 and MS7142 for the
- MB89120. The MS7141/42 drivers provide complete access to all devices and
- registers of the boards, in addition to the higher-level circuit packet
- switching capabilities.
