VALID ENTRIES:
NCI Code
NOTE 1: Valid NC codes are maintained by Telcordia Technologies.
USAGE: This field is conditional.
NOTE 1: Required when the ACT field on the ASR Form is “N” or “C”, otherwise optional.
DATA CHARACTERISTICS: 5 alpha/numeric characters minimum, 12 alpha/numeric characters maximum
EXAMPLES: 0 4 D X 2 . . A Z
NOTE 1: This example indicates no protocol options with transmission levels specified.
NOTE 2 : If the protocol option field is not coded and the Transmission Level Points (TLP) is coded, a double delimiter #1 and #2 will be placed after, character position five (5). In this case, delimiter #1 will be in character position six, (6) and delimiter #2 will be in character position seven (7). The TLP will be left justified into character positions eight (8) and nine, (9) accordingly.
