Front Panel Test Switch

The modem front panel has a five-position rotary switch that lets you select the modem’s operating mode. The five switch positions are:

cDATA use this position for normal data transmissions.

cAL (Analog Loopback) this position prepares the modem for testing by the local terminal device. The transmitter output of the modem is disconnected from the output coupling transformer and connected to the modem receiver input. See Figure 3-1.

cDL (Digital Loopback) this position configures the modem to loop back received data to the transmitter and transmit the data to the remote end. The RS-232-C interface to the terminal is not active during this test. See Figure 3-2.

cST (Self Test) this position inhibits the modem from transmitting and receiving data on the COMM LINE. The RS-232- C interface to the terminal is not active during this test. See Figure 3-3.

The test pattern (dot pattern) passes through the transmitter, loops back into the receiver, is demodulated, and is checked for errors. If errors occur, the TM LED turns OFF and remains OFF for a period of time that depends on the pattern generator baud rate.

In Analog Loopback and Self Test modes, the received analog data is buffered, amplified by 16 dB (if output level is set to 0 dB), and routed out on the transmit analog pair.

cTTP (Transmit Test Pattern) this setting forces the transmitter on and transmits data from the test generator to the COMM LINE. The RS-232-C interface lines (RTS, CTS, and Transmit Data) to the transmitter are not active. See Figure 3-4.

The TM LED goes ON when the receive data is good. If there are errors, or if the received data does not compare with the transmitted data, the TM LED goes off. The RS-232-C interface lines to the receiver are active during this mode.
