2. PRODUCT OVERVIEW
The Total Access 850 system (see Figure 1) is an
integrated access device designed for cost-effective
deploymentofvoice and dataservices atthe customer’s
premises. The Total Access 850 system benefits
integrated communications providers, such as CLECs,
ILECs, and ISPs, who require a customer premises
device that integrates voice and data functions, and
provides a viable migration path from TDM to packet-
based technology. The Total Access 850 features remote
management, an integrated IP router, and special
services slots.
Figure 1. Total Access 850
The Total Access 850 is a modular device, with two
common slots and eight access slots. Common cards
required for operation are a power supply unit (PSU)
and a system controller. System controllers include a
bank controller unit (BCU) (L1 and L2) and a router
control unit (RCU). The RCU includes a wide area
network interface (T1 or SDSL), DSX-1 PBX interface,
Nx56/64 V.35 interface, and built-in IP router. Six
access slots allow the user to combine a variety of voice
and 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 (only supported in
the BCU) and ISDN U-BR1TE. The other access slots are
used for Nx56/64 module with the BCU, the Echo
Cancellation card for use with the T1 ATM RCU, and
the DSX-1 card used with the T1 TDM RCU.
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
maintenanceprocedures.Hot-swappablemodulesmay
be replaced without disrupting other units. The four-
circuit-per-module design ensures that only four
analog circuits are affected when replacing a module.

Functional Description
The Total Access 850 System comprises the chassis,
common cards, and access modules. Associated with
the system are additional elements including an AC to
DC power supply and battery charging unit and a bat-
tery pack for backup power.
External AC and DC Power. The ADTRAN AC/DC
Power Supply/Battery Charging unit receives its
power from a standard 115 VAC outlet. The PSU
supplies a constant -48 VDC to the voice cards. The
power supply battery charging circuit maintains the
battery pack at peak charge. In the event of an AC
power failure, the battery backup circuit automatically
provides battery power to the PSU for up to 8 hours.
WhenACpower is restored, input power automatically
returns to the AC supply and the battery charging
circuit will recharge the battery to peak.
On the Total Access 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. Connector P6 is used when the
chassis is powered by the ADTRAN AC/DC Power
Supply unit (P/N 1175043L2) which mounts externally
to the chassis. Connector P7 is used when -48 VDC is
available on site and screw-type terminal connections
are required.
Figure 2. Total Access 850 Backplane
PSU. The Power Supply Unit supplies -48 VDC and
20 Hz ringing voltage to the RCU, BCUs, and access
modules. The PSU converts -48 VDC input to the
required voltages needed to operate all common units
andaccessmodules.Theringgeneratorcircuitprovides
20 Hz ring voltage to the analog access modules.
The PSU faceplate (see Figure 1 on page 1) shows the
following: a ring enable button, a power LED, a ring
LED, a bank alarm LED, and an alarm cutoff (ACO)
pushbutton switch. The separately fused ringgenerator
supplies up to 20 REN to the access modules.
BCU. The Bank Controller Unit is a common module
plug-in unit with a built-in CSU. The BCU provides all
controlfunctionsfortheTotalAccess850commonunits
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-9providestimingforDS0testequipment.Faceplate
LEDs show status information for the network and
Fractional (DSX-1) T1 (L2 only). The unit consists of a
main circuit board and daughter card and inserts
directly in the controller slot on the Total Access 850
shelf. An 8-position DIP switch is mounted on the
daughter card and is used for T1 provisioning and
clocking.
RCU. The Router Control Unit is a dual board assembly
that provides the network interface. The RCU can
provision, test, and provide status for any card in the
channel bank. A faceplate CRAFT DB-9 provides access
foraVT 100 terminalfor screenmenuprovisioning,and
bantam test jacks provide transmit and receive
monitoring. Faceplate LEDs show status information
for the network, V.35, and Ethernet ports.
WARNING
On Total Access 850 installations that do not use
all chassis slots, UL 1950/NEBS requires that the
empty slots must have a Total Access 850 blank unit
(part number 1175099L1) installed in the opening.

64200376L1-5A Issue 14, April 2003 3

Office Alarms. Backplane alarm connections(P5)are
labeled as shown in Table 2 on page 6 and illustrated in
Figure 7 on page 6. Alarm relay contacts are open
duringnormaloperation.Thealarmrelaycontactsclose
in the event of a local alarm condition or the receipt of
an alarm from the T1 carrier. In a carrier alarm
condition such as a Red, Yellow, or Blue (unframed all
1s), various alarm contacts in the PSU close. Carrier
alarm conditions cause the Total Access 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
during 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.
