The standard E&M board supports Types 1 or 2, two or four-wire
interfaces. The E&M-OD board supports a Type 5 interface.
Fax Interface
Each of the four BV1250 unit ports are capable of real-time fax
transmission using IP (T.38) transmission, thereby taking full advantage of
the data network’s flow and data control (TCP transmission).
DTMF Detect and Regeneration
BV1250 units are capable of detecting and regenerating DTMF signals.
Sending units are able to detect and convert DTMF tones for reliable
transmission. On the receiving end, the unit regenerates DTMF tones,
assuring accurate transmission when interfacing with Auto Attendant/Voice
Mail or Interactive Voice Response systems.
Voice Quality
All BV1250 units provide high-quality voice compression encoding which
can be configured on a priority basis to automatically select between
64kbps PCM stream as either G.729A (8kbps), G.723.1 (6.3kbps) or
G.723.1 (6.4kbps) compression, packet priority control, and bandwidth
management.
In addition, Oki’s proprietary dynamic jitter buffer and Dynamic Echo
Cancellation further assure uninterrupted and natural speech
communications.
Capacity
Each BV1250 unit supports up to four ports. Each of the four ports can be
configured for telephone service and any single port can be designated for
G3 fax service.
Network Connectivity
BV1250 units support a 10BaseT Ethernet interface for network
connection. WAN connectivity is provided through any IP router.

The E&M line interface board comes in two versions. The standard E&M board supports Type 1 and
Type 2 PBX interfaces. The E&M-OD board support a Type 5 PBX interface.
