CFA - Connecting Facility Assignment (PRILOC)

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.

USAGE: This field is conditional.

NOTE 1: Required when utilizing Wideband, High Capacity or Optical Network facilities when the ACT field on the ASR Form is ā€œNā€ or ā€œCā€, otherwise optional.

DATA CHARACTERISTICS: 42 alpha/numeric characters

EXAMPLES: 1 0 1 / T 1 / 3 / B S T N M A G T C G 0 / B S T N M A T C G 0

  1 0 1 / T 1 / 1 - 2 4 / B S T N M A G T C G 0 / B S T N M A M T C G 0

NOTE 1: The second example indicates the proper format for ranging channel assignments.
