5.2.2 REMOTE ANALOG LOOP
The second test mode is Remote Analog Loop. To enter this mode, set one of the Model 1050s (local) in test mode by depressing the "Loopback Test" switch. Any characters sent from the remote 1050 will be returned to it (see Figure 5). If no characters are echoed back, check the wiring between the two Model 1050s. Be sure to wire the units according to the instructions in Section 4.0 Installation.
