A communications device apparatus and method is detailed that allows for improved system statistics gathering of network communication links, dataports, and system status. The improved communications device apparatus and method utilizes a relative time reference or clock for the determination of the starting and ending of system statistics gathering time periods. Thus allowing for the contiguous gathering of system statistics without errors or gaps caused by time changes made to an absolute time reference.

Non-chronological system statistics

An apparatus and method are detailed that allows for improved detection of communication devices and/or doublers in an associated physical communication links, in particular on HDSL communication links. The improved device apparatus and method additionally allows for the communication device to identify when all devices on a communication link have been detected and prevent premature termination of a discovery process. The improved device apparatus and method also allows the avoidance of improper detection of communication devices or doublers due to corrupted discovery response messages.

Resilient detection of repeaters

A device apparatus and method are detailed that allow for improved bit error rate (BER) testing, configuration, and operation of a communication device and associated physical communication link, in particular on a HDSL communication device and link. The improved communication device apparatus and method additionally allow for the communication device to utilize an embedded BER tester (BERT) to run commonly utilized BER tests on high speed communication channels (downstream and upstream) associated with the communication device. The device apparatus and method also allow for a BER test to be configured and initiated remotely, with loopback at a remote device and masking of alarm states at the remote device or local device until the BER test is complete.
