Input Prompts for the NDC Option

Prompt        Valid Input                       Explanation
-----------------------------------------------------------------------------------------
SONUMBER      An entry in the format:           Service Order Identifier
                                                The unique number of the service order to
                abnnnnnc yy mm dd {AM} {PM}     be entered.  Date the service order is to
                                                be processed.
	      Where:

               * a = Obligatory Alphabetical
	             Character (A-Z)

               * b =  Optional Alphabetical
	              Character (A-Z)
	
	       * nnnnn = 5 Obligatory Numerical
	                 Characters
             
	       * c = Optional Alphabetical
	             Character (A-Z)

               * yy = Year (00-99)

	       * mm = Month (1-12)

	       * dd = Day (1-31)
----------------------------------------------------------------------------------------- 
DN_OR_LEN     Seven or ten digits.              Directory Number or LEN of the Line
                                                For MLH/DLH hunt members, if the user 
					        specifies a DN, the system prompts for the
                                                LEN.  If the user enters the LEN, the system
						does not prompt for the DN.
-----------------------------------------------------------------------------------------
OPTION        NDC                               No Double Connect

						modifies, or deletes.  The user can specify 
						a maximum of 20 options in each ADD, ADO,
						EST, or NEW command.

Assigning NDC

The following functionalities apply to the NDC option:

Notes

When a data unit line is created, the system adds the NDC option to the line.  The NDC option suppresses tests that can disrupt a data call.  The NDC option also prevents the communication of important information to users that are not authorized.  The system ignores the flashes and blocks Three-Way Calling (3WC) attempts when option 3WC is assigned to a 500/2500-type set.
