2 Issue 1, December 2003 61223424L2-5A Description The T200 H4TU-R can be deployed in ci rcuits using one H4TU-C, one H4TU-R, and up to two H4Rs. The T200 H4TU-R termin ates local loop HDSL4 signals originating from the Central Office (CO) unit and transforms the HDSL4 signal into traditional DS1 signals to be delivered to the customer. The T200 H4[...]

4 Issue 1, December 2003 61223424L2-5A Remote Provisioning There are no configuration switches for the T200 H4TU-R. Configuration is performed via software discussed in the Control Port Operation section of this practice. The provisioning settings can be vi ewed and manipu- lated through management access via the front pane l RS-232 port. Ta b l e [...]

6 Issue 1, December 2003 61223424L2-5A H4TU-R Network Loopbacks The loopback position is a logic loopba ck located within the H4TU-R internal HDSL4 transceiver. See Figure 4 . Figure 4. HDSL4 Loopbacks The H4TU-R responds to mu ltiple loopback activation processes: • First, manual loopback on the H4TU-R and/or the H4TU-C unit may be controlled fr[...]

61223424L2-5A Issue 1, December 2003 7 5. FRONT PANEL OPERATION The front panel contains two pushbuttons. These are labeled LOC and REM . The LOC pushbutton co ntrols a bidirectional loop back at the H4TU-R. Pressing the button causes a bidirec- tional loopback to occur. If th e bidirectional loopback is active, pressing the button a second time w [...]

61223424L2-5A Issue 1, December 2003 15 The System PM/Screen Report option ( Figur e 20 ) offers four types of reports on performance monitoring. Selecting a report type will th en display all the reports for that category on the screen at once, which is more efficient than stepping throug h the menus individually. The Clear PM and Alarm Histories [...]

16 Issue 1, December 2003 61223424L2-5A Item 12 on the Main Menu displays the Trouble shooting screen ( Figure 22 ). Helpful ADTRAN contact infor- mation along with two menu items appear on the bottom of this screen. Selecting option 1 from the T roubles hooting scre en causes the H2TU-C to read the operational status of the card and return T roubl[...]

61223424L2-5A Issue 1, December 2003 17 Selecting option 2 from the T roubleshooting screen accesses the General Information Screen ( Figure 24 ) that summarizes the deploy ment guidelines necessary to provision this HDSL4 circuit. The V irtual T erminal Session Sc reen ( Figure 25 ) allows control of the Remote card provisioning from the H4TU-C. P[...]
