The term data access arrangement
(DAA) has the following meanings:
-
In public switched telephone networks
, a single item or group of items at the customer side of the network interface
for data transmission
purposes, including all equipment that may affect the characteristics of the interface.
-
A data circuit
-terminating equipment (DCE
) supplied or approved by a common carrier
that permits a DCE or data terminal equipment
(DTE
) to be attached to the common carrier network.
Data access
arrangements are an integral part of all modems
built for the public telephone network. In view of mixed voice and data
access, DAAs are more generally referred to as Direct Access
Arrangements.
