Identifies the electrical conditions on the circuit at the ACTL/Primary Location.
NOTE 1: The format and structure of this field is defined by ANSI in document T1.223, Structure and Representation of Network Channel (NC) and Network Channel Interface (NCI) Codes for the North American Telecommunications System. The Network Channel Code consists of the following elements:
1. Total Conductors - Positions 1 and 2 identify the total number of
physical conductors (e.g., wires) required at the interface (2 numeric
characters).
2. Protocol - Positions 3 and 4 identify the requirements for the interface
regarding signaling and transmission (2 alpha characters).
3. Impedance - Position 5 identifies the nominal reference impedance that
will terminate the channel for the purpose of evaluating transmission
performance (1 alpha/numeric character).
4. Delimiter #1 - Position 6 identifies the start of the protocol option
field if a protocol option code is assigned.
5. Protocol Options - Positions 7, 8 and 9 identify additional features
(e.g., bit rate, bandwidth, etc) on the protocol to be used. (3 alpha/numeric
characters)6. Delimiter #2 - Position 10 identifies the start of the Transmission
Level Points (TLP) field if a TLP is assigned.
7. Transmission Level - Positions 11 and 12 identify the TLPs from either
the exchange carrier /service provider or customer end.
NOTE 1: Position 11 identifies the TLP transmit signal level at the EC/service provider when transmitting to the customer.
NOTE 2: Position 12 identifies the TLP receive signal level at the EC/service provider when receiving from the customer.
NOTE 3: If TLP is entered in one character position only (transmit or receive), a hyphen or the letter "O" is required as a field filler in the associated TLP character position.
NOTE 4: If TLPs are not to be coded, default levels found in Telcordia Technologies Technical Publications will apply and the TLP character positions will be left blank.
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.
