Performance

Although the features of the BV1250 go a long way toward assuring clear
voice communications and error free fax transmission over digital data
networks, some network conditions can cause performance degradations.

Common causes include:

•

Voice PAD settings not correctly configured.

•

Many collisions among packets within the Local Area Network
(LAN).

•

Number of hops packets go through is too large.

•

High traffic conditions are prevalent on the network.

•

Routing through a firewall.

•

Wide Area Network (WAN) transmission delays.

•

Internet Service Provider (ISP) has inadequate service characteristics.

The methods used to prevent problems and optimize performance depend
on the type and configuration of the network equipment in use. Below are
some suggestions that may prove useful.
