Applies only to X25 DLM Switched Virtual Circuits (SVCs). For
 outgoing circuits, specifies the remote DTE address and subaddress
 that this DLM circuit will call. For incoming circuits, specifies the
 address of the remote DTE from which this circuit will accept calls.

 If the NUMBER parameter is not specified for an incoming circuit, a
 call from any remote DTE can be directed to this circuit. Specify a
 decimal integer of 1 to 15 digits.
