CFA

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 by ANSI in document T1.238, Structure for the Identification of Telecommunications Facilities for the North American Telecommunications System. 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.
