Determine whether 
modems are assigned 
to answer and 
originate.
Ensure one modem is set to 
answer (AT
*
CA1) and one to 
originate (AT
*
CA0).
Run an LAL pattern 
test (AT&T8) on both 
modems.
• If errors are found on either 
end, contact Motorola 
customer service.
• If the modem passes the test, 
you may have line problems; 
contact your telephone 
company.
Check the modulation 
configuration:
• Mode (AT
*
MM)
• Max Rate (AT
*
MX)
• Min Rate (AT
*
MN)
Ensure that the local and remote 
modem modulation modes are 
compatible.
Check local and remote 
leased line transmit 
level (AT
*
LX).
• USA: if operating on a leased 
line, set to 0 (AT
*
LX0)
• If the transmit level is 
adjustable in your country, and 
the modems are running back-
to-back, adjust it to 
approximately -15 dB 
(AT
*
LX15)
