DESCRIPTION

The Single 4-Wire TO Access Module was designed for use in the Total Access

1500

Chassis. The 4W TO Access Module provides a voice grade 4-wire analog interface

between a VF transmission facility and the Total Access 1500 backplane. The 4W TO

Access Module generates no signaling, but in-band signaling tones that are part of

the data stream will be passed transparently.

Features

■ One DC-isolated, 4-wire VF channel interface

■ Extended operating temperatures from –40ºC to +65°C

■ Transmission Level Point (TLP), transmit input and receive output ranges are

adjustable in 0.1 dBm increments

■ Supports loaded and non-loaded cable types

■ Supports Sealing Current Modes: None, Sink, or Source

■ Provisioning via the SCU ADMIN port or remote craft interface

■ Digital loopback and 1004 Hz, Digital Reference Signal (DRS) Tone Tests via the SCU

ADMIN port or remote craft interface

TURN-UP STEPS

Unpack the 4W TO Access Module and inspect it for damage. If damage has occurred,

file a claim with the carrier, then contact ADTRAN Customer Service.

Insert the 4W TO Access Module into any access-module slot on the Total Access 1500

as follows:

(a) While supporting the bottom edge of the circuit board, hold the 4W TO Access

Module by the front panel.

(b) Align the Access Module’s edge within the guide groove of the chassis.

into the chassis backplane.

(d) Lock the Access Module in place by pushing in on the locking lever.

Time Slot Assignments

The Total Access 1500 can automatically map DS0s in the T1s as determined by the

LIU operational configuration, or manual mapping is available via a local or remote

terminal interface. For default time slot assignments in the Dual T1 mode and in the

Quad T1 mode, refer to the Installation and Maintenance Practice, P/N 61180112L2-5.

Connections

Four 50-pin male amphenol connectors, (P1, P2, P3 and P4), on the rear of the Total

Access 1500 chassis provide the interconnect wiring for the shelf access module’s

physical slots. The 4W TO Access Module uses P1 (T/R) and P2 (T1/R1) for the port 1

connections. For details, see Installation and Maintenance Practice, P/N

61180112L2-5.

Monitor the LEDs for operational status.

FRONT PANEL LED (PORT 1)

STATUS ● Green Port is operating normally

● Yellow Port is in a menu controlled test

● Red Port failure has been detected

Provision the 4W TO Access Module locally using the SCU ADMIN port.

Connect a VT100 compatible terminal to the common equipment’s DB-9 ADMIN port.

(The ADMIN port is used for provisioning, testing, and performance monitoring func-

tions.) Start the terminal emulation program. If using Windows HyperTerminal, open

by selecting Programs/Accessories/HyperTerminal. Login and navigate through

ADMIN port menu structure.

NOTE: To ensure proper display background, select VT100 Terminal Emulation under

settings.

Navigate through the menus to perform the desired function.

TEST OPTIONS

The 4W TO Access Module supports a Digital Network Loopback and 1004 Hz Tone

Tests to support circuit turn up and maintenance efforts. Test functions can be

activated locally via the ADMIN port on the SCU, or remotely via Telnet or SNMP.

Digital Network Loopback Test

The Digital Network Loopback test activates a loopback path that takes the DS0 data

received from the network and transmits it back to the network 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, which is used to send DRS signal to the loop, the network, or to both

simultaneously.
