indication is modiÞed to be RING:1234567. This is called the 
concatenated format.

The second format is a Tag = Value pair, where the only supported 
tag is NMBR. The same example would return the string 
NMBR = 1234567 on its own line after the Þrst RING indication.

A query may be sent during ringing that returns the calling line ID 
information. This feature is independent of the delivery enable 
feature.

The Calling Line ID Delivery Control Command 

@N1=value

controls whether calling line ID is delivered on incoming calls.

Value 0 (the default) disables calling line ID delivery. Value 1 
enables calling line ID delivery using the concatenated format. 
Value 2 enables calling line ID delivery using the tag and value 
format.

OK  Appears when the value is understood and calling line ID is 
supported.

ERROR  Appears when the selected value is not recognized or is not 
supported.
