FDL Interface

Overview

Overview

The Facility Data Link (FDL) interface is a management channel in the T1 Extended Superframe Format (ESF) described in ANSI standard T1.403. The Access Navigator uses this 4Kbps channel to communicate with the Adit 600 TDM and Access Bank II families of T1 voice and data access products.

Carrier Access provides provisioning and monitoring of remote Adit 600 and Access Bank II terminals using a Carrier Access FDL (CA FDL) protocol to send commands over the FDL channel.
