Read Stored Number

Selecting item 2 in the Dial Menu lets you view the phone number

currently stored in the Model 2500RC Series non-volatile memory.

Dial New Number

Selecting item 3 in the Dial Menu lets you dial a number other than

the one stored in non-volatile memory.  When you select this menu
item, the Model 2500RC Series responds with this prompt:

Enter up to 12 digits (without hyphens or other alphabetic characters),
followed by [RETURN].  For example: “13015551212.”

After dialing the number, the Model 2500RC Series will display the
message, “Dialing” and then display each number as it is dialed.  The
Model 2500RC Series will then prompt the user to wait while the
connection is made.  One of the following messages will then be
displayed to indicate the success or failure or the connection:

CONNECT:

The called unit has answered.

NO WINK:

The central office did not send a wink signal 

within 5 seconds of line seizure.

SHORT WINK:

A wink signal less than 120 milliseconds

was received.

LONG WINK:

A wink signal greater than 320 milliseconds 

was received.

NO CARRIER:

The called unit did not answer within 30 

seconds.

DTR OFF:

DTR must be on to dial.

OFF HOOK:

The Model 2500RC Series is already off-hook 

and in data mode.

NOTE:

The control port will not respond to additional commands 

until one of the above response messages is issued.

Hang Up

Selecting item 4 in the Dial Menu terminates the call.
