Page 19: Diagnostics
DIAGNOSTICS The following pages provide hardware techniques for diagnosing communication problems and thereby isolating the problem at the local modem, the remote modem or the interconnecting line. (a) LOCAL ANALOG LOOPBACK (Figure 2) Requires a loop back cable with a built-in circuit for line loss to simulate a typical leased line condition (See Figure 3). - Page 20 Test 3: Received Signal Level Set Dip Switch 1 OFF (TxA = -10dBm) and Dip Switch 3 OFF (RxA = -43dBm). CD will be ON. Run a test message at TxD and verify that the same message is received at RxD with no data errors. Test 4: Repeat Test 3 for various RTS/CTS delay times and with soft carrier ON and OFF.
- Page 21 (c) REMOTE DIGITAL LOOPBACK – 4/Wire Network (Figure 5) Configure both the local and remote modems as follows: Switch 1 = ON (TxA = 0dBm) Switch 3 = ON (RxA = -33dBm) Switch 4 = OFF (RTS/CTS = 35ms) Switch 5 = ON (RTS/CTS = 35ms) Switch 6 = ON (Constant Carrier mode).
- Page 22 (d) LINE DIAGNOSTICS (i) Typical modem configuration for 4-wire Point-to-Point system… Switch 1 = ON (TxA = 0dBm) Switch 3 = ON (RxA = -33dBm) Switch 4 = OFF (RTS/CTS = 1ms) Switch 5 = OFF (RTS/CTS = 1ms) Switch 6 = ON (Constant Carrier mode). Switch 7 = OFF (4-Wire) Switch 8 = ON (Line Termination = 600 ohms) Switch 9 = OFF (Soft Carrier = OFF)
