Operational Test
After installing your modem, it is preferable to carry out an
operational test on a local level to check out whether the modem
is working all right and the telephone line is exactly matched.
We suggest you carry out the test as follows:
●
Connect the DTE to the modem on the marked connector with
the MAIN PORT.
●
Switch the modem on and check out whether there is live
voltage from the power supply with the PWR (that should be
on).
●
Following this LED lamps C107 (DSR) and C109 (DCD)
should light up, the modem will in fact be programmed
according to its default value that envises the criteria DCD and
DSR forced to operate.
●
Check out whether the telephone line is correctly hooked up;
you only need to lift up the telephone receiver and check that
there is a dialing tone, then press the push-button DATA; the
modem should “pick up” the telephone line and you should no
longer hear the dialing tone in the telephone receiver. By
pressing DATA once again, the modem will restore the
telephone line.
●
Digit the code number “AT” from the terminal, the modem
should answer with “OK”.
●
Press the push-button TEST: by enabling this (line loop), the
warning “CONNECT...” followed by the connection speed
