Motorola V3229 Operating Instructions - Page 226

Test Procedures Step 2 ¥If the circuitry is working properly, the front panel indicators show the following: ¥Configure the modem for LOCAL ANALOG LOOP to switch the transmitter back to its normal data input . ¥The modem should display on the local monitor whatever is entered at the local DTE. ¥If the transmit data input is in a mark hold condition, both the TD and RD indicators should remain off. ¥If the transmit data input is in a space hold condition, both the TD and RD indicators should come on. All other indicators should remain the same except for CS which should turn on. ¥If the indicators are correct, the modem is probably operating correctly. ¥If the preceding tests were not successful, call Technical Services. This step determines the performance of the local and remote modems and the telephone circuits. It also determines each modem's ability to receive a transmitted signal from the other site, properly equalize and decode the signal, and then loop this regenerated signal into the transmitter for transmission back to the other modem. This test applies to both leased line and dial line applications. -D ¥Configure the local modem for REMOTE DIGITAL LOOP WITH TEST PATTERN. This signals the remote modem to go into digital loop.
