unlikely event you encounter a problem with your modem.
Local Modem Test
The local modem test verifies the local modem’s transmitter, receiver,
and connection to the locally attached DTE. This test can be run either
by generating a data pattern from the locally attached DTE or by
having the modem generate a test pattern.
The following procedure describes how to run the local modem test
using a locally attached DTE to generate a data pattern.
1.
Using the front panel test switch, place the modem in Analog
Loopback mode.
2.
Turn on the Request To Send line.
3.
Use the locally attached DTE to transmit the data pattern and
check for data errors on the Receive Data line.
The following procedure describes how to run the local modem test
using the modem test pattern instead of a data pattern originated by the
local DTE.
1.
Using the front panel test switch, place the modem in Self Test
mode.
2.
The
TM
indicator should turn ON. If the indicator turns OFF or
flashes, errors are occurring.
