Options - ADTRAN 850 Installation And Operation Manual

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 le-
ver.
CAUTION
This product is intended for installation in Re-
stricted Access Locations only and is intended to be
installed in equipment with a Type "B" or "E" in-
stallation code.

3. OPTIONS

The TA 850 BCU can be provisioned from either an 8-po-
sition Dual In-line Package (DIP) switch (S1) mounted on
the PCB, or through screen menus accessed via the face-
plate 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 mod-
ules are available through the craft ADMIN interface.
DIP switch S1 must be provisioned while the BCU is
withdrawn from the chassis. Once installed, any soft-
ware 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 If the unit is withdrawn and reinserted (power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switch setting is changed while withdrawn, the new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 mod-
ule 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 re-
moved from the chassis. If inserted into another
chassis, the provisioning setup is invoked on that
chassis' access modules.

Time Slot Assignment (Plug and Play Environ-
ment). 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 automati-
cally 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.
