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

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.

Features

The features of the Total Access 1500 FXO/GT, P/N

1180115L2, include the following:

• Nominal 600 ohms or 900 ohms (+2.16 µF)

2-wire VF interface with DC isolation

• Transmit TLP range of -9.0 to +7.5 dBm

• Receive TLP range of -11.5 to +6.0 dBm

• FXO Loop Start, FXO Ground Start, TR-08

2. INSTALLATION

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. Hold the unit by the faceplate while

supporting the bottom side.

2. Align the card edges to the guide grooved for

the designated slot.

3. Insert the card until the edge connector seats

firmly into the backplane.

4. Push the ejector in place to ensure the unit is

fully seated.

Compliance

Table 1 shows the Compliance Codes for the Total

Access 1500 FXO/GT. The FXO/GT complies with

UL 1950, third edition. It is intended for installation

in restricted access locations only and in equipment

with a Type “B” or “E” installation code.

Table 1. Compliance Codes

edoCtupnItuptuO

)CP(edoCrewoPCC

)CT(edoCnoitacinummoceleT-X

)CI(edoCnoitallatsnIA-

This device complies with Part 15 of the FCC rules.

Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference

received, including interference that may cause

undesired operation.

Changes or modifications not expressly approved by

ADTRAN could void the user’s authority to operate

this equipment.

Time Slot Assignment

Each FXO/GT uses one DS0 in one of the following

configurations:

• 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

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.

6. MAINTENANCE

The Total Access 1500 Dual FXO/GT requires no

routine maintenance for normal operation.

ADTRAN does not recommend that repairs be

performed in the field. Repair services may be

obtained by returning the defective unit to ADTRAN.

Refer to Warranty and Customer Service section for

further information.

7. SPECIFICATIONS

Specifications for the Total Access 1500 FXO/GT are

detailed in Table 7.
