1. GENERAL
This practice provides installation and maintenance
procedures for the ADTRAN Total Access 1500
Foreign Exchange Office with Gain Transfer (FXO/
GT) Access Module. Figure 1 is an illustration of the
Total Access 1500 FXO/GT.
Revision History
This is the initial release of this document. Future
revisions to this document will be explained in this
subsection.
General Description
The Total Access 1500 FXO/GT Access Module is
intended to be deployed in the Total Access 1500
Chassis. The FXO/GT provides for a 2-wire 900 ohms
or 600 ohms + 2.16 µF interface between a VF
transmission and signaling facility and a Pulse Code
Modulation (PCM) interface. The unit contains the
61180115L2-5A
Figure 1. FXO/GT Front Panel
necessary circuitry to convert between analog voice/
data signals from the customer’s loop and the PCM
digital data signal. The FXO/GT channel unit also
contains a ring detector circuit to monitor the loop for
ringing signals, and can be used in loopstart or
groundstart applications. The FXO/GT provides a
Precision Balance Network (PBN), slope equalizer,
and Line Build Out Capacitance (LBOC) circuitry.

configurations:
C A U T I O N !
SUBJECT TO ELECTROSTATIC DAMAGE
OR DECREASE IN RELIABILITY.
HANDLING PRECAUTIONS REQUIRED.
•
Remove the Total Access 1500 FXO/GT from the
carton and visually ensure that damage has not
occurred during shipping or handling. If damage has
occurred, file a claim with the carrier, then contact
ADTRAN. Refer to the Warranty and Customer
Service section of this practice.
•
The FXO/GT inserts into any Access Module slot
(1 through 24) of the Total Access 1500 chassis.
•
To install the FXO/GT, perform the following steps:
1.
2.
2
Hold the unit by the faceplate while
supporting the bottom side.
Align the card edges to the guide grooved for
the designated slot.
Single T1 configuration - The LIU assigns
one DS0 associated with T1-A to each of the
Physical Slots 1-24 in the Total Access 1500
Chassis.
Dual T1 configuration - The LIU assigns
two DS0s from T1-A to Physical Slots 1-12
and two DS0s from T1-B to Physical Slots
13-24.
Quad T1 configuration - The LIU assigns four
DS0s from T1-A to Physical Slots 1-6, four
DS0s from T1-B to Physical Slots 7-12, four
DS0s from T1-C to Physical Slots 13-18, and
four DS0s from T1-D to Physical Slots 19-24.
The FXO/GT will always use the first DS0 associated
with the Physical Slot, unless the LIU is in a Manual
Mapping mode. Table 2 details the DS0 physical port
assignments.

Connections
Four 50-pin male amphenol connectors on the rear of
the Total Access 1500 chassis provide the
interconnect wiring for each of the access module
physical slots. The Total Access 1500 FXO/GT
requires P1 (Pair 1 T/R) for wiring out the FXO/GT
circuit. See Table 2 for wiring interconnect details.
3. PROVISIONING
The Total Access 1500 FXO/GT may be provisioned
by either hardware switches or from a DB-9, VT100
craft port on the Total Access 1500 SCU. Table 3
explains provisioning options available through the
DB-9 VT100 craft port on the SCU. Table 4
describes the Precision Balance Network (PBN)
options. Table 5 describes the DIP switch settings.
Password and User ID
Password protection is factory disabled. If password
protection is enabled, then the SCU will display the
log on screen, and a valid user ID and password are
required to access menus. The factory default user ID
is USER, and the default password is PASSWORD;
both are in all capital letters. Both the user ID and
password are required.

5. TEST FEATURES
The Total Access 1500 FXO/GT supports a Digital
Network Loopback and a 1004 Hz Tone Generation
test to support circuit turnup and maintenance efforts.
These tests are initiated from the Total Access 1500
Local Craft Port on the SCU.
Digital Network Loopback Test
The Digital Network Loopback provides a loopback
path for the DS0 data from the network. Received data
of the selected port is latched in on the appropriate
receive time slot on the receive bus, and then placed
on the transmit bus in the appropriate port’s transmit
time slot.
1004 Hz Tone Test
The 1004 Hz Tone Test generates a 1004 Hz @ 0
dBm Digital Reference Signal (DRS) tone toward the
T1 Network, toward the customer loop, or both
directions simultaneously.
