Port Interface Cards

Port Interface Cards (PICs)

Providing an array of physical interfaces, Port
Interface Cards (PICs) offer flexibility when 
configuring Allied Telesis routers and Rapier

TM

L3

switches to work in a variety of network
topologies and physical media. Users can modify
or replace PICs to meet changing network
requirements—or they can enhance perform-
ance via the cards’ on-board I/O controllers.

By taking advantage of Allied Telesis’s wide
range of PIC options, your company can be
assured of graceful migrations from one inter-
face to another without having to replace core
equipment, resulting in reduced capital, training,
deployment, and management requirements as
your network evolves.

The AT-AR027 FXS (Foreign Exchange Service)
PIC provides low-density, high-quality, full-duplex,
inter-site voice/fax communication over IP.
Combined with an Allied Telesis router or
Rapier Layer 3 switch it will allow up to eight
telephones or faxes to be connected to a Local
Area Network.

The AT-AR027 fully complies with Industry
Standard Protocols, such as VoIP, H.323 v2, SIP,
G.711 A/µlaw, G.723.1 and G.729 A/B (optional).

The AT-AR027 also provides support for 
various voice CODECs i.e. G.711 (A/µlaw)
vocoder 64Kbps, G.723.1 (5.3 and 6.3Kbps) and
G.729 A/B (8Kbps) (optional).
