General Description
The TA 750 BCU is a common module plug-in unit
designed for the TA 750. The BCU, with a built-in
CSU, provides all control functions for the TA 750
common units and all individual access modules. A
faceplate ADMIN DB-9 provides access for a VT 100
terminal for screen menu provisioning, and bantam
test jacks provide, transmit, and receive monitoring.
An additional TEST DB-9 provides timing for DS0
test equipment. A network LED shows status
information for the network T1. The unit is comprised
of a main circuit board and daughter card and inserts
directly in the BCU slot on the TA 750 shelf. An 8position DIP switch is mounted on the daughter card
and is used for T1 provisioning and clocking.
This device complies with Part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference,
and (2) this device must accept any interference
received, including interference that may cause
undesired operation.

Changes or modifications not expressly approved by
ADTRAN could void the user's authority to operate
this equipment.
Functional Description
The TA 750 BCU provisions, operates, monitors, and
tests all TA 750 access modules including Quad FXS,
Quad FXO, OCU DP, DS0 DP, and Nx56/64 DSU
DP. The BCU programs T1 bandwidth use between
the various access modules and data ports.
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withdrawn from the chassis.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 If the unit is withdrawn and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withdrawn then the new DIP switch setting takes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.
2. INSTALLATION/OPERATION
C A U T I O N !
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
After unpacking the unit, inspect it for damage. If
damage is noted, file a claim with the carrier, then
notify ADTRAN Customer Service, see section 7.
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.
Compliance Codes
This product is intended to be installed in products
providing Type "B" or "E" enclosure, and in a
Restricted Access Location. Refer to Table 1.

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:
• 9600 Baud
• No parity
• 8 Data bits
• 1 Stop bit
CAUTION
The BCU retains provisioning setup when
removed from the chassis. If inserted into
another chassis, the provisioning setup is
invoked on that chassis' access modules.
WINDOWS HYPERTERMINAL
Windows Hyperterminal can be used as a VT 100
terminal emulation program. Open Hyperterminal by
selecting PROGRAMS / ACCESSORIES /
HYPERTERMINAL. Refer to the Help section of
Hyperterminal for additional questions.

NOTE
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.
