Identifies the interface characteristics on the circuit at the ACTL/Primary Location.
NOTE 1: The format and structure of this field is defined in ANSI approved standard, ATIS-0300223, Structure for the Identification of Network Channel (NC) and Network Channel Interface (NCI) Codes for Information Exchange. The Network Channel Code consists of the following elements:
VALID ENTRIES:
NCI Code
NOTE 1: Valid NCI codes are maintained by Telcordia Technologies.
USAGE: This field is conditional.
NOTE 1: Required when the ACT field on the ASR 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.
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.
0 4 D B 2
NOTE 1: This example indicates no protocol options and transmission levels to be at the default level.
0 4 D S 9 . 1 5 K
NOTE 1: This example indicates protocol options specified and transmission levels to be at the default level.
