1ABOUT THE PRODUCT

The ADC Campus™ G.703 Interface Card provides a connection between a High-bit-rate Digital Subscriber Line (HDSL) and a network or other digital equipment to transport digitized voice, data, and video signals over existing copper wire at an E1 rate.

There are two versions of the Campus-RS G.703 Interface Card. The first provides a 75-ohm unbalanced coaxial interface, the other provides a 120-ohm balanced twisted pair interface. With both versions, the card:

• provides a full E1 (2048 kbps) data payload transfer rate

• uses HDB3 line coding

• must derive clock source through the input data signal from the host equipment

The Campus-RS G.703 Interface Card installs into one of the following to create a Campus-RS system:

• Campus-Star chassis, along with a Campus-RS Line Unit

• Campus-RS Desktop Unit

The Campus-RS G.703 Interface Card must be installed in a Campus-RS Desktop Unit or with a Campus-RS Line Unit. It cannot be installed in an older Campus desktop unit or with an older Campus line unit.

Chapter 1: About the Product

This chapter describes how to set and view the individual configuration options through an ASCII terminal. To use an ASCII terminal to view system performance and other status information, see Chapter 5.

You can perform these functions through the LCD on the front of either the Campus-HRS Line Unit installed in the Campus-Star or the Campus-HRS Desktop Unit, see Chapter 3.

CONNECTING TO AN ASCII TERMINAL

To connect the Campus-HRS Line Unit or Desktop Unit to an ASCII terminal:


• If the ASCII terminal provides an RJ48 jack, plug the console cable into the ASCII terminal jack.

• Otherwise, plug the console cable into the adapter, then plug the adapter into the standard 9-pin COM port on the ASCII terminal and tighten the attached screws until they are snug.

Chapter 4: Configuring through an ASCII Terminal (Console)



● lug the other end of the console cable into the console port on the desktop unit.

• If a unit is set to Master, it initiates the HDSL link. The other Campus unit must be set to Slave or Auto.

• If a unit is set to Slave, it waits for the other Campus unit to initiate the HDSL link. The other unit must be set to Master or Auto.

Unless you have an important reason for doing otherwise, leave the Transceiver Mode option set to Auto.

6TESTING THE SYSTEM

The Campus-RS G.703 Interface Card supports a complete set of loopback functions that allow you to test the data communication path between the host equipment, the Campus unit, and the remote unit. You can use either the LCD and menu buttons or an ASCII terminal to initiate loopback tests.

To use an LCD to initiate a loopback, see “Configuring Loopbacks” on page 11. To use an ASCII terminal to initiate a loopback, see “Configuring Loopbacks” on page 21.

Initiating a loopback test interrupts normal system operation, which causes the Test LED on the Campus HRS Desktop Unit or Line Unit front panel to turn on. When the loopback is cancelled, the system automatically returns to normal operation.

Chapter 6: Testing the System


TYPES OF LOOPBACKS

The Campus-RS G.703 Interface Card supports the following loopback test:

● Local to Local Interface

● Remote to Local Interface

● Local to Remote Interface

● Remote to Remote Interface

Each loopback tests a different portion of the communication path, which lets you isolate communication problems. For each test, the terms “local” and “remote” are relative to the Campus unit from which you initiate the loopback test.

Local to Local Loopback

The Local to Local loopback verifies that the local host equipment, local G.703 cable, and local interface card are installed and configured properly. The remote host equipment is not involved in this loopback.

Types of Loopbacks


Remote to Local Loopback

The Remote to Local loopback tests the remote port, the entire data path inside the local and remote Campus units, the HDSL line, and the HDSL transceivers of both units. Use this loopback to verify that the HDSL line is operational and that the HDSL transceiver of the remote unit is operational. The remote host equipment is not involved in this loopback.

Local to Remote Loopback

The Local to Remote loopback tests the local port, the entire data path inside the local and remote Campus units, the HDSL line, and the HDSL transceivers on both units. The local host equipment is not involved in this loopback.

Remote to Remote Loopback

The Remote to Remote loopback verifies that the remote host equipment, remote data interface cable, and remote interface card are installed and configured properly. The local host equipment is not involved in this loopback.

The remote interface card determines which remote loopbacks available. Depending upon the remote interface card type, some remote loopback options may not be available.

Chapter 6: Testing the System


TERMINATING LOOPBACKS

You can terminate (clear) all loopback tests in the following two ways:

● cancel the loopback manually from either the LCD or an ASCII terminal

● set the Loopback Timeout option to cancel the loopback automatically after a set period of time

Clearing Loopbacks Manually

You can clear a loopback from either the LCD or an ASCII terminal. To use the LCD, see “Terminating All Loopbacks” on page 12. To use an ASCII terminal, see “Terminating All Loopbacks” on page 23.

Loopback Timeout

When a loopback is in use, there is a possibility that it will be forgotten. If a loopback remains in use, the communication link remains down. The Loopback Timeout configuration option provides a way to prevent this from happening by setting how long a loopback remains active.

You can set the Loopback Timeout to 20, 60, or 120 minutes. Then, when a loopback is enabled, it terminates automatically and the HDSL link is reestablished after the Loopback Timeout duration has elapsed.

To set the Loopback Timeout through the LCD, see “Setting a Loopback Timeout” on page 12. To set the Loopback Timeout through an ASCII terminal, refer to “Setting a Loopback Timeout” on page 23.
