General Description
The TA 850 BCU is a common module plug-in unit designed for the TA 850. The BCU, with a built-in CSU,
provides all control functions for the TA 850 common
units and all individual access modules. A faceplate
ADMIN DB-9 provides access for a VT100 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 comprises a main circuit board and daughter card and inserts directly into the BCU slot on the TA
850 shelf. An 8-position DIP switch is mounted on the
daughter card and is used for T1 provisioning and
clocking.
Functional Description
The TA 850 BCU provisions, operates, monitors, and
tests all TA 850 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.
2. INSTALLATION/OPERATION
After unpacking the unit, inspect it for damage. If damage is noted, file a claim with the carrier, then notify
ADTRAN Customer Service (see “WARRANTY AND
CUSTOMER SERVICE” on page 5).

The TA 850 BCU plugs directly into the controller slot
in the common module area of the TA 850 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.
CAUTION
This product is intended for installation in Restricted Access Locations only and is intended to be
installed in equipment with a Type "B" or "E" installation code.
3. OPTIONS
The TA 850 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 3 on page 4 for DIP switch S1 pro-
visioning information. Additional and more in-depth
provisioning options for the BCU as well as access modules are available through the craft ADMIN interface.
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withdrawn from the chassis.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 If the unit is withdrawn and reinserted (power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, the new
DIP switch setting takes effect. If none of the DIP switch
settings were changed, the unit will be provisioned for
the last software settings.
Electronic Provisioning
The ADMIN interface on the TA 850 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-male 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
To ensure proper display background in Windows
Hyperterminal, select VT 100 terminal emulation
under SETTINGS.
Password. When connected, enter the password. The
factory default is PASSWORD in all capital letters. The
password can be changed to a user selected password
once connected.
Menu Navigation. To traverse through the menus, se-
lect the desired entry and press Enter. To work backwards in the menu, press the Esc (escape) key.
Time Slot Assignment (Plug and Play Environment). The TA 850 can support a plug and play envi-
ronment for slots 1-6 of the TA 850 bank for the various
access modules (i.e., FXS, FXO, OCU DP, DSO DP,
UBRITE, E&M, etc.). Each card that is plugged in to
slots 1-6 will consecutively take 4 Time Slots automatically when installed in the TA 850 bank, depending on
the card that is plugged into the shelf.
Time Slot Assignment - Software Assignment
(Non-Plug and Play Environment). Slots 1-6 of the TA
850 Bank are for the various access modules supported
by the the TA 850 (i.e., FXS, FXO, OCU DP, DSO DP,
UBRITE, E&M, etc.). The T1 interface on the TA 850
BCU supports 24 Time Slot Assignment which can be
allocated to the access modules, to the DSX-1, or to the
Nx64 module. The TA 850 BCU can override the plug
and play assignments through the software menus via
the ADMIN port on the TA 850 BCU.

Faceplate TEST connector
The faceplate DB-9 female TEST connector provides the
necessary clock output required by standard DSO Logic
Test equipment such as a TPI 108/109 test set. Specifically, the TEST connector outputs 8 kHz and 64 kHz
clock reference signal. Figure 3 on page 5 illustrates the
DB-9 TEST connector.
Table 1. Pinout Connectors for RJ-48 T1 Interface
Connections
All TA 850 BCU connections are made through the
backplane connector. With the exception of power and
the V.35 connector, all of the TA 850 rear panel connectors terminate on the BCU. These include Network T1,
Clock source, Alarms, Fractional T1, and Management.
Refer to the TA 850 System Installation and Maintenance Practice, part number 64200376L1- 5A, for additional information on rear panel connections. Table 1
describes the T1 pinout connections.
Faceplate LED
The faceplate Network LED labeled T1 Network provides status information for the network T1 using a color coded message format. Refer to Table 2.
4. TESTING
The TA 850 BCU provides a variety of test options for
both the Network T1 and DS0 access modules. The faceplate of the BCU provides a bantam jack for local T1 test
access. DS0 test access for the digital access modules
(OCU DP, DS0 DP, U-BR1TE) is provided via bantam
jacks on the faceplate of each unit.
Faceplate Bantam Jack
The faceplate bantam jack provides a means to monitor
the network T1 connected to the rear of the TA 850 chassis. The jacks accept standard 310-type bantam plugs.
