Test Procedures
This test is valid only in 4-wire operation. The
initiating modem signals the remote modem to go to
Remote Analog Loopback. The remote receive
leased line connects to the transmit leased line
through a buffer amplifier (Figure 3-4). The remote
modem transmitter goes off, but its receiver stays
connected and waits for the signal to end the test.
