Switch S1-8: V.54 Enable / Disable

The setting for switch S1-8 determines whether the Model 1094 will respond when it receives the V.54 sequence. If you suspect the Model 1094 may be getting tricked into the loopback test by false detection of user data, you can try setting this to “Disable.”

4.0 INSTALLATION

Once the Model 1094 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 CONNECTION TO THE TWISTED PAIR INTERFACE

The Model 1094 supports communication between two terminal devices at distances to 4.9 miles (7.9 km) and data rates to 768 kbps. There are two essential requirements for installing the Model 1094:

1.These units work in pairs. Therefore, you must have one Model 1094 (or a compatible model) at each end of a two twisted pair interface.

2.To function properly, the Model 1094 needs two twisted pairs of metallic wire. These twisted pairs must be unconditioned, dry, metallic wire, between 19 and 26 AWG (.4 mm and .9 mm, inversely) (the higher AWG gauges may limit distance somewhat). Standard dial-equalization equipment, or standard, flat modular telephone type cable, are not acceptable.

4.1.1TWISTED PAIR CONNECTION USING RJ-45

The Model 1094 uses a modular RJ-45 jack for twisted pair line connection. The signal/pin relationships are shown below:
