Revision History
This is the initial release of this document. Future revisions to this document will be described in this subsection.
TA 850 system benefits integrated communications
providers,such as CLECs,ILECs, andISPs, who require
a customer premises device that integrates voice and
data functions, and provides a viable migration path
from TDM to packet-basedtechnology. The TA 850
features remote management, an integrated IP/IPX
router, and special services slots.
Figure 1. TA 850
TheTA 850 is a modular device,with two common slots
and eight access slots. Common cards required for operation are a powersupply unit (PSU) and a routercontrol unit (RCU). The RCU is a card that currently
supports TDM-based applications, but can be easily upgraded to an ATM-based controller as requirements
change. The RCU includes a T1 network interface,
DSX-1PBXinterface,Nx56/64V.35interface,andbuiltin IP/IPX router. Six access slots allow the user to combine a variety of voiceand data services. Up to six Quad
FXS or Quad FXO access modules can be installed to
support up to 24 analog voice lines. Other access modules for data applications include the OCU DP and
ISDN U-BR1TE. The other two access slots are for future hardware options.
Using local or remote inband management, carriers can
turn features, functions, and access ports on and off.
Easy access to modules, common cards, power supplies, and the battery back-up system simplify maintenance procedures. Hot-swappable modules may be
replaced without disrupting other units. The four-circuit-per-module desig n ensures that only four analog
circuits are affected when replacing a module.
2. PRODUCT OVERVIEW
The TA 850 system (see Figure1) is an integratedaccess
device designed for cost-effective deployment of voice
and data services at the customer’s premises. The

Functional Description
The TA 850 System comprises the chassis, common
cards, and access modules. Associatedwith the system
are additional elements including an AC to DC power
supplyandbatterychargingunitandabatterypackfor
backup power.
WARNING
On TA 850 installations that do not use all chassis
slots, UL 1950/NEBS requires that the empty slots
must have a TA 850 blank unit (part number
1175099L1) installedin the opening.
External AC and DC Power. The ADTRAN AC/DC
Power Supply/Battery Charging unit receives its power from a standard 115 VAC outlet. During operation,
the power supply maintains -54 VDC to the PSU. The
power supply battery charging circuit maintains the
battery pack at peak charge. In the event ofan AC power failure, the battery backup circuit automatically provides battery power to the PSU for up to 8hours. When
AC power is restored, input power automatically returns to the AC supply and the battery charging circuit
will recharge the battery to peak.
On the TA 850 chassis, the incoming power termination
point is on either of two backplane connections: P7 or
P6. (See Figure 2.) Both sources connect directly to the
PSU.ConnectorP6isusedwhenthechassisispowered
by the ADTRAN AC/DC Power Supply unit (P/N
1175043L1) which mounts externally to the chassis.
ConnectorP7 is used when-48 VDC is available on site
and screw-type terminal connections are required.

Figure 2. TA 850 Backplane
PSU. The Power Supply Unit supplies -48 VDC and
20 Hz ringing voltage to the Router Controller Unit
(RCU) and the access modules. The PSU converts
-48 VDC input to the required voltages needed to operate all common units and access modules. The ring generator circuit provides 20 Hz ring voltage to the analog
access modules.
ThePSUfaceplate(seeFigure1onpage1)showsthe
following: two GMT fuses (one for power and one for
20 Hz ringvoltage), a channel bank status LED, and an
alarm cutoff (ACO) pushbutton switch. The separately
fusedring generator supplies upto 20 REN tothe access
modules.
RCU.The Router Controller Unit isa dual boardassembly that provides the networkinterface. The RCU can
provision, test, and provide status for any card in the
channelbank. The faceplate hasa DB-9
CRAFT
port connection, dual bantam jack connection, plus network,
V.35, and Ethernet LEDs.
Access Modules. The TA 850 is designed to support
Quad FXS, Quad FXO, OCU DP, and UBR1TE access
modules.

removed. Make wire-wrap or screw terminal
connections as follows:
1.Unscrew the access cover hold-down screw.
2.Slide the access cover down slightly to disengage the
lock-tabs from their slots.
CAUTION
Use wire gauge suitable for the application.
3.Identify the wire-wrap pins designated for use, and
make the connectionsstartingwith thepinsclosest to
the exit port to avoid wiring interference as work
progresses.
4.If alternate power connection to P7 is to be used,
make those terminal connections last.
5.Carefully route wiring through the exit port.
6.Position and align the access cover tabs to the slots;
insert the tabs and slide the cover up slightly until
the screw holes arealigned. Ensurethatexit wiring is
not pinched or damaged.
7.Reinsert the hold-down screw.
Customer Connection. One 50-pin male amphenol
connector (P2) provides the interconnect wiring for the
access modules located in slots 1 through6 of the chassis. This connector is usually terminated with a punchdown block for premises wiring or connected directly
to a cross-connect or main distribution frame. Figure 4
on page 5 details the connector pinout.
T1 Connection. There are two termination pointsfor
connecting the network T1 to the chassis: the primary
RJ-48 connector (JP2) and the alternate wire-wrap pins
on terminal strip P3 (as shown in Figure 2 on page 2).
Only one connector type is used (not both).

Office Alarms. Backplane alarm connections(P5) are
labeled as shown inTable 2 on page 6 and illustrated in
Figure 7 on page 6. Alarm relay contacts are open during normal operation. Thealarm relaycontacts closein
the event of a local alarm condition or the receipt of an
alarm from the T1 carrier. In a carrier alarm condition
suchas a Red, Yellow, orBlue (unframed all 1s), various
alarm contacts in the PSU close. Carrier alarm conditions cause the TA 850 to initiate trunk processing. The
following chain of events then occur:
1.MJ will be directly shorted to MJR.
2.MJV will be directly shorted to MJVR.
Contacts MJ and MJR can be overridden manually dur-
ing an alarm condition by pressing the ACO pushbutton on the PSU faceplate. If the 3-Amp power fuse on
the PSU trips, the -48ALM relay will close, providing a
-48 VDC signal on that pin. This alarm cannot be overridden by the ACO pushbutton. Refer to Table 3 on
page 6 for alarm notifications.
