BV1250 Overview
Oki BV1250 Internet Voice Gateways (IVGs) are self-contained H.323 Version 2
compliant communications devices (Gateways) that allow organizations to route
both voice and fax communications over any TCP/IP network.
Oki BV1250 IVGs can be used to seamlessly bridge PSTN, PBX, Key Telephone,
and analog telephone systems with digital data networks, allowing organizations
to more fully exploit their existing intranet and internet facilities. Most
importantly, since communications take place over digital data networks, the high
cost of long distance communications over conventional telephone networks is
virtually eliminated.
In the simplest sense, a BV1250 IVG unit converts outgoing voice or fax signals
into a digital format, compresses and packages the signal for transmission over
digital TCP/IP networks. On the incoming side, the IVG reverses this process,
receiving voice or fax data packets and translating them back into appropriate
voice and fax signals.

In summary, Oki’s IVGs provide organizations with a reliable one-box solution
for high quality integrated voice and facsimile communications using existing
LAN/WAN environments without interrupting or compromising ongoing data
communications.

OVERVIEW Oki BV1250 Installation Guide
Page 4 of 334 Revision 1.0
The BV1250 IVG incorporates many features that help to assure a robust and
easy-to-use product that delivers high quality voice communication and error free
fax transmission.
Modularized Base Unit
The BV1250 IVG base unit has a compact modular design that allows it to
be configured for easy installation and connection within existing network
environments.
Physical configuration is accomplished by installing the desired board or
boards in the base unit.
Line Interface Options
Oki’s modular design permits identical base units to be quickly and easily
set up with different line interface boards-- AP/FXS, FXO, E&M, and BRI.
These boards provide support for most telephone communications
interfaces and can be interconnected using RJ or DDK type connectors.
FXS: The AP/FXS line interface board is installed in units that will be
connected to simple analog devices such as telephones, fax
machines, and Key Telephone Systems (KTS).1
1The AP and FXS boards are interchangeable. In this document this interface is referred to as AP/FXS
or FXS.

Oki BV1250 Installation Guide OVERVIEW
Revision 1.0 Page 5 of 334
FXO: The FXO line interface board is installed in units that will be
connected directly to a PSTN or to the analog station/line ports of a
PBX.
E&M: Install an E&M line interface board in units that will be connected
directly to a Private Branch Exchange (PBX) E&M interface.2
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.
2The 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.

OVERVIEW Oki BV1250 Installation Guide
Page 6 of 334 Revision 1.0
Interoperability
All BV1250 IVGs, irrespective of their configurations, are interoperable
among themselves and with other OKI Internet telephony products. In
addition, all BV1250 units are H.323 Version 2 compliant and when
installed in H.323 Version 2 compliant networks, are interoperable with
other H.323 Version 2 compliant devices.
H.323 Compliance
All Oki BV1250 units are H.323 Version 2 compliant.
When implemented within an H.323 network, units are simultaneously
managed as H.323 compliant gateways, using H.323 Gatekeeper device call
control, address management, and bandwidth control capabilities.
IP and Telephone Numbering Management
Oki BV1250 units employ a unified telephone numbering management
system. It is easy to create a numbering plan that conforms to existing PBX
and PSTN numbering plans.
IP to telephone-number translation can be handled in a number of ways.
1. In H.323 compliant networks (e.g. Gatekeeper devices are employed)
translations are handled by an H.323 Gatekeeper device.
2. In networks not employing an H.323 Gatekeeper, IP to telephone-
number translations can be handled by external DNS (Domain Name
System) servers
3. In the absence of external DNS servers are the internal DNS
capabilities of BV1250 units can be used.

Oki BV1250 Installation Guide OVERVIEW
Revision 1.0 Page 7 of 334
4. Finally, external and internal DNS capabilities can also be combined to
optimize network performance.3
Mounting
BV1250 units can be installed on a desktop or rack-mounted in a standard
19" rack configuration, using the optional rack mounting kit.
SNMP Capabilities
Oki BV1250 units can be configured to use network management control
through SNMP (Simple Network Management Protocol - MIBII).
Remote Control and Management
Installation and configuration of the BV1250 units is performed using Oki’s
Maintenance Console Software (MCS) running on the Windows 95
operating system.
For first-time installation the Maintenance Console Software is used in
conjunction with a common RS232C interface in order to establish a unit’s
new IP addressing. Once this is done and units are on-line in the network,
the Maintenance Console Software can be used to configure and
troubleshoot units remotely.
Alternatively, BV1250 configuration files can be manually configured and
uploaded to units, or BV1250 on-line configuration commands can be
entered directly to a unit. The advanced unit configuration techniques are
applied using an RS-232, LAN, or a Telnet/FTP link.
3Using this configuration can restrict interoperability with other manufacturer’s H.323 devices.
