3.1 Basic Configuration Overview
The BV1250 IVG is an H.323 Version 2 compliant Internet Voice Gateway
device. Units are designed to provide voice and fax transmission over an IP
network, permitting the creation of voice/fax networks over any IP compatible
intranet and Internet. Interfaces are provided for standard analog telephone
terminals, Key Telephone Systems, PBX equipment, G3 fax, and PSTNs.
BV1250 network IP-to-telephone number translation can be managed using H.323
Gatekeeper functions or can be handled through external DNS server facilities or
the BV1250’s internal DNS functions.
A basic configuration is shown in Figure 3-1.
A few conditions must be met for a BV1250 IVG installation.
•
Each BV1250 unit must be connected to the LAN using an Ethernet interface
and must be connected to the WAN (e.g. IP network) using a router.
•
Only one IP network (Internet, Intranet, and VAO) can be used to
interconnect communicating devices.
•
The BV1250 requires that the network used support static IP addressing.
Static addressing means that the IP addresses allocated to various
devices in the network are represented by fixed values. In some
network applications, particularly large ones, addresses are
sometimes dynamically allocated (DHCP/BOOTP). When this is the
case, a block of IP addresses must be allocated for static
assignment for all BV1250 units.
