latest statement of service from your ISDN provider.
• Your ISDN provider may have programmed the switch incorrectly. Call the provider.
You cannot place two simultaneous data calls
• You may not have ordered an ISDN line configuration that supports two simultaneous calls. Check your
contract or latest statement of service from your ISDN provider. Also, your ISDN provider may have
programmed the switch incorrectly. Call the provider.
• You may have misconfigured your TA to dial two simultaneous data calls. The command
AT&J1&W0<cr> is used to indicate whether outgoing calls should be made on two B-channels by
default.
• You may be using the wrong bundling dial modifier (e.g., ATD7853500&7853502<cr>). The ampersand
in this command string is correct. Note other valid characters joining two telephone numbers include a
Plus Sign (+) and an exclamation Mark (!).
Note: In Windows 95, if the Use Country Code and Area Code box is checked in the Properties window for
dial-up connection, the bundling modifier (i.e., &, + or !) is removed from the dialing string when the user
attempts to make a connection. The solution is to not check the Use Country Code and Area Code box or to
simply add the bundling dial modifier to the phone number at the time of connection.

or because you exceeded your time limit for the day. Try again.
The terminal adapter cannot connect when answering
• Autoanswer may be disabled. Turn on autoanswer in your data communications program, or send the
command ATS0=1 to your TA in terminal mode.
Note: To accept calls while DTR is low, configure the TA to ignore DTR by entering AT&D0<cr>. Configured
this way, the TA accepts calls while DTR is low. Otherwise the TA rejects incoming calls until DTR is high
while the calls come in.
