CTA 500 dm On Line Guide
BUSY Appears when the connection was not completed due to
detection of a busy indication in the network.
ERROR Appears when the command was issued while in the On-
line Command State, if a stored dial string was speciÞed and the dial
string was empty, or if the CTA 500dm is out-of-sync and the
network is unavailable.
The Answer Command
instructs the CTA 500dm to answer an incoming call immediately.
Successful completion of this command does not necessarily
indicate the establishment of a rate adaptation call using both B-
channels, but it refers to the establishment of the channel.
Any additional characters on the command line are ignored.
The Answer Command can be aborted by the reception of a single
character if the character is received before the command is
complete.
CONNECT rate When the call is answered, the connect indication
displays along with the rate of the connection to the network (not the
rate of the connection between the CTA 500dm and the attached
computer) either 56,000 or 64,000 bit/s.
Immediately after this indication displays, the device enters the data
mode.
OK Appears when the command is aborted by the assertion of DTR
and if &D is either 1, 2 or 3 (see
page 56
for more details).
ERROR Appears when the command is issued while in the On-line
Command State, if there is no incoming call, or if the CTA 500dm is
out-of-sync with the ICS.
NO CARRIER Appears when connection is not established due to
an error or an abort.
