AT-VP504E FXO

2

How does it
Work?

The AT-VP504E FXO is a gateway. When a PSTN user contacts the
AT-VP504E FXO, the call is answered and a second dial tone (IP dial
tone) is presented to the PSTN user. The number dialed at this
moment will be parsed by the AT-VP504E FXO and used in an H.323
call establishment.

The AT-VP504E FXO contacts an H.323 compliant gatekeeper. The
gatekeeper then looks through its internal database to translate the
dialed number to a corresponding IP address. If none exists, the
gatekeeper will locate a gateway (which can be another AT-VP504E
FXO) for placing the call on the PSTN.

When an Internet telephony call is placed from one location to another,
the voice signals pass through the AT-VP504E FXO. They are
compressed into data packets, which are then diverted by the
AT-VP504E FXO onto an IP/data network such as the Internet, or
another type of data network. Upon reaching its destination, the data is
converted back into voice signals, then fed into the corresponding
endpoint.

The AT-VP504E FXO system utilizes technology that optimizes
available bandwidth, so users do not hear echoes, stops and starts, or
annoying clicks and pops. When traffic congestion is properly
managed, AT-VP504E FXO customers cannot tell that their
conversation is being carried over a packet network rather than the
traditional PSTN.

See

“AT-VP504E FXO Call Processes” on page 53

for more details on

AT-VP504E FXO call process and other examples.

Features

The following table lists some of the features the AT-VP504E FXO
offers.

Feature

Description

4 FXO Ports

Ports that will act as FX Office (FXO) ports, enabling the
unit to be integrated into many existing telephony
configurations. These ports support both Loop Start and
Ground Start lines.

Fax Interface

Handles G3 and Super G3 fax transmissions at speeds
up to 33.6 kbps. Automatic fax mode detection is
standard on all ports.
