Troubleshooting M2000 Series Meridian Digital Telephones (Part 3 of 4)
Symptom
The prompt CALL
CONNECTED. SESSION
STARTS is followed by
RELEASE.
Garbled prompts are sent to
your terminal when you type
<CR>.
You are connected to a host
computer, but get no response
when you try to log on.
You try to make a data call from
the initial prompt (or Main menu)
in keyboard dialing. You see the
prompt CALLING.
MCA does not operate at all.
Solution
Check the configuration parameters of the far end data
device. If they do not match those of the MCA, the call will
be dropped. Change the parameters of your MCA to match.
Enter a period ( . ) followed by <CR> to perform an
autoparity.
First, release the call. Turn on Remote Loopback and make
the call again. Type some characters at the terminal. If the
characters echo back and appear on the terminal, the
problem is with the far end data device. If the characters do
not appear on the terminal, the problem is with the MCA.
Contact the telephone system administrator.
First, hold down the break key(s) for two seconds, enter
<CR>, and try again to make the data call. If the problem
persists, the MCA is probably disabled. Contact the
telephone system administrator.
1 Check the LED in the back of the telephone to see if it
is flashing. If the LED is steadily lit, the MCA needs to
be configured in the system, or it may be bad. If the
LED is not lit, the MCA requires external power.
2 Make sure the cable from the terminal or PC is
connected to the MCA.
3 Check the data parameters for the display.
4 Be sure the transformer is plugged in, or the closet
power is connected.
5 Be sure the cable between the MCA and the
telephone is connected and has not been pinched.
6 Be sure the power card is installed correctly. Verify
that the jumper settings are correct for either RS-232
or V.35 (whichever you are using).
