Title:
TEST ACCESS SYSTEM AND METHOD FOR DIGITAL COMMUNICATION NETWORKS
Document Type and Number:
WIPO Patent Application WO1999034549
Kind Code:
A9
Abstract:
The system includes a number of line access devices, each of which is coupled to at least one of the communication lines, both ends of which terminate at telecommunications termination sites. One or more monitoring buses are defined by a number of relays, one or more of which is coupled to one of the line access devices. A test device interface, which is selectively coupled to the bus, provides bi-directional connectivity between the selected communication line and a selected testing device coupled thereto. An activated one or more of the relays couples a selected one of the communication lines to a selected one of the testing devices via the test device interface. One or more signal paths defined as passing through the relays, test device interface, and a portion of the line access devices define untapped point-to-point connections.
