NOTE 1: The format and structure of this field is defined in the ANSI approved standard, ATIS-0300223, Structure for the Identification  of Network Channel (NC) and Network Channel Interface (NCI) Codes for Information Exchange or by COMMON LANGUAGE in BR-795-403-100. A brief summary of the format can be found in ATIS-0404000 Section 2.14.7.   

VALID ENTRIES:

NCI Code

NOTE 1: Valid NCI codes are outlined in Telcordia Technologies.

USAGE: This field is conditional.

NOTE 1: Required when the ACT field on the ASR Access Service Request Form is "N", “C” or “T”, otherwise optional.

DATA CHARACTERISTICS: 5 alpha/numeric characters minimum, 12 alpha/numeric characters maximum

EXAMPLES: 0 4 D B 2 . . A Z

NOTE 1: This example indicates no protocol options with transmission levels specified.

   0 4 D B 2

NOTE 2: If the protocol option field is not coded and the 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.
