Appendix D - AT Command Summary

D.3 Result Codes
When the TA receives an AT command from the computer or terminal, it attempts to execute the
command, then sends a status message to the computer or terminal that reports the result of the
command. The TA provides you with several of these response messages, or result codes, which can
be displayed on your monitor or intercepted and used by your communications software. Using the
Vn command, you can select whether the result codes are terse (numbers) or verbose (words).
The TA’s result codes are listed in the following table. Note that the speed of an ISDN B-channel is
always either 56Kbps (CONNECT 56000) or 64Kbps (CONNECT 64000) unless the call is a V.110
call in which case the reported connection speed with be that of the V.110 network rate.
