PROVISIONING
The Total Access 750/850/1500 OCU DP supports two types of provisioning modes, local and remote.
Local provisioning results in the module operating as defined by the on-board switches. Remote
provisioning results in the module operating as defined by the Bank Controller Unit (BCU) or System
Controller Unit (SCU) menu settings (on-board switches are ignored). The operational mode is
indicated by the LED and can be changed by depressing the
REM
Remote Provisioning
The craft interfaces on the BCU or SCU are used to change default options and obtain access module
status through menu screens. To access the menu screens, connect a VT100 terminal or a computer
running a terminal emulation program to the front panel craft interface ADMIN port using a standard
male-to-female RS-232 DB-9 cable.
Windows HyperTerminal can be used as a VT100 terminal emulation program. Open HyperTerminal
by selecting
Programs/Accessories/HyperTerminal
additional information.
To traverse through the menus, select the desired entry and press
menu press the (escape) key. The figure on the right illustrates the OCU DP menu tree.

TESTING
The OCU DP is equipped with logic level bantam test access jacks that permit testing in both directions
using a portable test set. Latching and alternating OCU and CSU loopback sequences are supported.
Alternating loopbacks do not operate when the 64 kbps data rate is selected. Choose NEAR to test
toward the 4-wire customer loop direction; choose FAR to test toward the T-carrier.

In the FAR direction, an OCU loopback sequence will loop the unit directly across the carrier system.
In the NEAR direction, an OCU loopback sequence will loop the unit directly connected to the portable
test set.
