Page 13: Chapter 2: Bv1250 Overview
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.
Page 14 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.
Page 15 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.
Page 16 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.
Page 17 Finally, external and internal DNS capabilities can also be combined to optimize network performance. 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).

Page 40: Worksheets
Whether the installation is simple or more complex, configuration information needs to be on-hand once the installation of a BV1250 unit begins. This information should be determined during the network planning process.
Page 41 Also, if DNS facilities are used instead of an H.323 Gatekeeper, this information must be supplied to the DNS entities so that all BV1250 units can be made aware of one another. Reproduction masters for all worksheets in this section are included in Appendix J: of this document.
Page 42 This worksheet is designed for use as a master list of key unit information and is useful in planning the deployment of units. The seven fields are to be completed for each BV1250 unit installed in the network. The information contained on this worksheet will be transferred to individual unit setup worksheets discussed later in this chapter.
Page 43 The procedure for creating Groups is discussed in Section 5.6 of this document. Each BV1250 unit must be assigned to a Group. The New Group command is used to enter this information in the Maintenance Console Software. Although the Maintenance Console Software requires that this be done before units (Gateways) can be defined, it is used for unit identification only and is not recorded in the unit’s...
Page 44 In the sample worksheet the unit names are simply numbered units, e.g. Unit 1, Unit 2, etc. See Chapter 2: for an overview of the various unit types. Also see the BV1250 Technical Reference for a complete description and specifications for each unit type.
