The TA 750 BCU plugs directly into the BCU slot in
the common module area of the TA 750 chassis. To
insert, hold the unit by the faceplate while supporting
the bottom side. Align the card edges to the guide
grooves for the designated slot. Insert into the chassis
until the edge connector seats firmly into the
backplane. Lock the unit in place by pushing in on
the locking lever.

Restricted Access Location. Refer to Table 1.
3. OPTIONS
The TA 750 BCU can be provisioned from either an
8-position Dual In-line Package (DIP) switch (S1)
mounted on the PCB, or through screen menus
accessed via the faceplate craft interface port. Basic
T1 provisioning, clock source, and CSU loopback
options are found on the DIP switch. Refer to
Table 2 for DIP switch S1 provisioning information.
Additional and more in-depth provisioning options for
the BCU as well as access modules are available
through the craft ADMIN interface.

SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
DIP switch S1 must be provisioned while the BCU is
withdrawn from the chassis. Once installed, any
software provisioning made will override the DIP
switch settings. If the unit is withdrawn and
reinserted (power cycled) the software options remain
in effect. If a DIP switch setting is changed while
withdrawn then the new DIP switch setting takes
effect. If none of the DIP switch settings were
changed then the unit will be provisioned for the last
software settings.

Electronic Provisioning
The ADMIN interface on the TA 750 BCU is used to
change factory selected options and obtain access
module status through menu screens. To access the
menu screens, connect a VT 100 terminal or computer
running a terminal emulation program to the craft
interface port using a standard male-to-female RS-232
DB-9 cable. Craft port settings are as follows:
