HDSL2 System Testing HDSL2 for General Distribution Installation and Maintenance Practice12 61223HDSL2L2-5BProvisioning Options, Total Access 3000 H2TU-CThe Total Access 3000 H2TU-C is provisioned through the SCU on the Total Access 3000chassis. In addition to the options shown in Table 6 on page 11, the options shown in Table 7apply.HDSL2 SYSTEM TESTINGThe ADTRAN HDSL2 system provides the ability to monitor the status and performance of theDSX-1 signals, DS1 signals, and HDSL2 loop signals. Detailed performance monitoring isprovided by the front panel-mounted RS-232 control port (or via the SCU RS-232 port for theTotal Access 3000). These features are valuable in troubleshooting and isolating any systemlevel problems that may occur at installation or during operation of the HDSL2 system.Additional testing features are described below.Table 7.

This setting allows active connections to the DSX orMUX interface; however, no alarms will be generated. Out-of-Service Unassigned allows the loops to train upbut will not connect to the DSX or MUX interface. The In Service setting allows full functioning connections toDSX or MUX interfaces.2. For Network Source settings, the following options apply:• DSX-1: The module will utilize the DSX-1 interface. The Muxes will not be used, even if present.• Mux A: The module will use Mux A as its data source. The module will not switch to Mux B in the case of aMux A failure. The EQ jacks can be used as a temporary test point in conjunction with the EQ jack settingon the loopback/test screen.• Mux B: The module will use Mux B as its data source. The module will not switch to Mux A in the case of aMux B failure. The EQ jacks can be used as a temporary test point in conjunction with the EQ jack settingon the loopback/test screen.• Auto Mux: The module will default to Mux A as its data source. In the event of a Mux A failure, the modulewill perform a protection switch to Mux B if it is present and in service. The EQ jacks can be used as atemporary test point in conjunction with the EQ jack setting on the loopback/test screen.
