All existing latching loopbacks can also be disabled by pressing the TEST or LBK pushbutton on the U-BR1TE or remote unit, respectively.

NOTE

The remote end test feature is only supported when the upstream U-BR1TE is an ADTRAN D4 or Series 5 U-BR1TE with DDS Loopback capability. Other U-BR1TEs will ignore the loopback command sent by pressing the IDSL OCU-R LBK button.

5. CONTROL PORT OPERATION

The IDSL OCU-R front panel DB-9 provides an RS-232 interface for connection to a controlling terminal. The pinout of the DB-9 is illustrated in

Assignments

NOTE

When conducting a Terminal Session, always select VT100 mode prior to making the craft connection.

The terminal interface operates at data rates from

1.2kbps to 19.2 kbps. The asynchronous data format is fixed at 8 data bits, no parity, and 1 stop bit. The supported terminal type is VT100 or compatible.

NOTE

If using a personal computer (PC) with terminal emulation capability, disable all power saving programs. Otherwise, communication between the PC and the IDSL OCU-R unit can be disrupted, resulting in misplaced characters or screen timeouts.

Operation

The T200 IDSL OCU-R is ready for synchronization and operation upon insertion in an active shelf or housing. Terminal sessions provide access to screen menus for provisioning, monitoring, testing, or obtaining performance history. Terminal session screen access is available at any time during operation. The screens shown in this practice identify the main menu screens; subordinate screens are not depicted. Abbreviations used in the screen diagrams are detailed in Table 8.
