The Model 1092A Test Modes are described on the following page.

To run or terminate a particular test, key in the option to get to that screen menu.

OFF

Terminates all tests

511

Initiates the built-in test pattern generator

 

and detector.

511 with Errors

Initiates the built-in test pattern generator

 

and detector. The test pattern generator

 

also injects intentional errors approximately

 

once per second.

Local Line Loop

Initiates the Local Line Loop test and starts

and 511

the internal 511 generator and detector.

Local Line Loop

Initiates the Local Line Loop test and starts

and 511 w/errors

the internal 511 generator and detector. In

 

this test, the 511 pattern generator injects

 

intentional errors into the data stream.

Remote Digital

Initiates the Remote Digital Loopback test.

Loop

Any data sent to the remote 1092A is

 

returned to the originating device.

Remote Digital

Initiates the Remote Digital Loopback test

Loop and 511

and starts the internal 511 generator and

 

detectors.

Remote Digital

Initiates the Remote Digital Loopback test

Loop and

and starts the 511test patterns. In this test

511 with errors

the 511 pattern generator will inject initial

 

errors into the data stream.

The Modem Status Screen is displayed upon initiating a test. Press ‘ESC’ to return to the Test Mode Menu.

Press the space bar to update and redisplay the status.

4.0 INSTALLATION

Once the Model 1092A is properly configured, it is ready to connect to the twisted pair interface, to the serial port, and to the power source. This section tells you how to make these connections.

4.1 CONNECTING THE TWISTED PAIR INTERFACE

The Model 1092A supports communication between two DTE devices at distances to 5 miles (8 km) over 24AWG (.5mm) twisted pair wire. There are two essential requirements for installing the Model 1092:

1.These units work in pairs. Both units at the end of the twisted pair must have the same 2-Wire or 4-Wire setting. For instance, if the application is a 2-Wire application, then both units must be in the 2-Wire setting.

2.To function properly, the Model 1092A needs one or two twisted pairs of metallic wire. This twisted pair must be unconditioned, dry, metallic wire, between 19 (.9mm) and 26 AWG (.4mm) (the higher number gauges may limit distance somewhat). Standard dial-up telephone circuits, or leased circuits that run through signal equalization equipment, or standard, flat modular telephone type cable, are not acceptable.

The RJ-45 connector on the Model 1092A’s twisted pair interface is polarity insensitive and is wired for a two-wire or four-wire interface. The signal/pin relationships are shown in Figure 4 below.
