ECCKT - Exchange Company Circuit ID

Identifies a provider circuit ID or multiple circuit IDs

NOTE 1: The provider assigning this circuit identifier determines the content of this field in accordance with COMMON LANGUAGE standards maintained by Telcordia Technologies

NOTE 2: When the UNE field on the ASR Access Service Request form is populated, and the customer is ordering an unbundled multiplexer, the COMMON LANGUAGE Format of the transport facility for the high speed and low speed sides may be different.

NOTE 3: When a component within the format is purposely omitted, the component should still be delimited and compressed to eliminate any spaces.

NOTE 4: All components within the ECCKT should be delimited by either virgules or periods.

NOTE 5: If all positions in a component within the ECCKT are not populated, the component should be compressed to eliminate any spaces.  

NOTE 6: Use of ranging is based on customer/provider negotiations. Ranges should be shown within the appropriate component of the ID by specifying the lowest value of the component, hyphen, and highest value of the component, e.g., trunk numbers 3500 through 3512 would be shown as 3500-3512.

NOTE 7: The format and structure of the field is defined in ANSI approved standards.
