Nortel Networks CTA 500dm Press any key before the call is completed to abort the Dial Command

	AT commands 45
Character	Use
Svalue	dial string is taken from a stored telephone number
	(value is the location of the stored number; see the
	“General” commands section for more information)

The type of dialing depends on the type of network chosen to route the call, so the directives t (tone) and p (pulse) have no meaning and are ignored.

The ; command line terminator prompts the CTA 500dm to dial the string, attempt to make the connection, and immediately change to the On-line Command State (rather than the On-line Data State) upon connection.

Using S value allows linking of the stored dial strings. For example, if S0 has the string 9-1-800-, S1 has the string 123-4567 and S2 has the string 123-5678, then issuing the command ATDS0S1&S0S2 is the same as the command ATD9-1-800-123-4567 & 9-1-800-123- 5678.

Command.

Result Codes

OK Appears when the command is aborted by the assertion of DTR and if &D is either 1, 2 or 3 (see theÒSerial Interface Control LinesÓ on page 56 for the commands).

CONNECT rate When the call is successfully completed, 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) as either 56,000 or 64,000 bit/s.

Immediately after this indication displays, the device enters data mode. DCD is asserted if &C is 1 (see ÒSerial Interface Control LinesÓ on page 56 for more details).

Note: Data protocols that require the use of both B-channels of the TCM have only a CONNECT 112000 or CONNECT 128,000 message (not both), since both calls will not be completed simultaneously.

NO CARRIER Appears when connection was not established due to an error or an abort.
