Identifies the provider carrier system and channel to be used from a Wideband Analog, High Capacity or Optical Network facility when the customer has assignment control.
NOTE 1: The format and structure of this field is defined in the ANSI approved standard, ATIS-0300097, Structure for the Identification of Communications Connections for Information Exchange. The Connecting Facility Assignment consists of the following elements:
1. Facility Designation – A code that, for a specific type of facility,
uniquely identifies a path between two network nodes (1-5 alpha/numeric
characters).
2. Facility Type - A code that describes a type of facility when it is
other than a single baseband channel on cable. Valid entries are
outlined in Telcordia Technologies practice BR 795-450-100 (1-6 alpha/numeric
characters).
3. Channel/Pair/Time Slot - A code that identifies a specific assignable
portion of a facility (1-5 alpha/numeric characters).
4. Location A - A standardized code that uniquely identifies the location
of facility terminal A, which has the lower in alpha/numeric sequence
of the two facility location codes. Valid entries are outlined in Telcordia
Technologies practice BR 795-(100-186)-100 (8 or 11 alpha/numeric characters).
5. Location Z - A standardized code that uniquely identifies the location
of facility terminal Z, which has the higher in alpha/numeric sequence
of the two facility location codes. Valid entries are outlined in Telcordia
Technologies practice BR 795-(100-186)-100 (8 or 11 alpha/numeric characters).
NOTE 2: Virgules are used as delimiters to separate all elements of the CFA .
NOTE 3: All element entries of the CFA are left justified with no trailing spaces.
NOTE 4: The Facility Designation portion identifies the FNI of the existing ring which this ordered service will overlay.
USAGE: This field is conditional.
NOTE 1: Required when overlaying a ring, otherwise optional.
