Outgoing data calls are not possible.
(Error identified at Outgoing Data Call Test,
Step 3)
Incoming data calls are not possible.
(Error identified at Incoming Data Call Test,
Step 2)
If MLH is expected, the possible causes are:
— CO provisioning does not allow incoming
data calls, but either the DN or MLHG DN
has been verified to be correct.
IF MLH is not expected, the possible cause is:
— Provisioning on the facility does not allow
incoming data calls.
Provisioning on the facility does not allow
incoming data calls.
(Error identified at Outgoing Data Call Test,
Step 3 and/or Incomig Voice Call Test Step 2.)
This condition may or may not be detected by any
single manual test. Therefore, a sequence of calls
may be necessary to determine the condition for the
failure.
