Management via SNMP The Qlink-3000 multiplexing modem may be equipped with a SNMP control port. The SNMP control port is located on the front panel, and has a standard Ethernet 10Base-T interface (RJ-45). The SNMP protocol allows to view current device modes, link states, local and remote error statistics, to change configuration parameters, and to enable diagnostic modes.

Built-in BER tester The Qlink-3000 multiplexing modem has a built-in BER tester, which allows to perform error rate measurements in the SHDSL link. The measurements are performed using fixed or pseudo-random code according to the O.151 recommendation (the pattern length is 2 15 -1=32767 bits). The BER tester is controlled from the console (see the “Test” menu” section) or via an additional Ethernet port using the SNMP protocol. If remote control is allowed, then the BER tester may be controlled from a terminal connected to the console port of th
