Identifies the provider assigned Ethernet virtual connection identifier.
NOTE 1: The provider assigning this EVCID determines the content of this field in accordance with COMMON LANGUAGE standards maintained by Telcordia Technologies.
NOTE 2: When a component within the format is purposely omitted, the component should still be delimited and compressed to eliminate any spaces.
NOTE 3: All components within the EVCID should be delimited by either virgules or periods.
NOTE 4: If all positions in a component within the EVCID are not populated, the component should be compressed to eliminate any spaces.
NOTE 5: The format and structure of the field is defined in ANSI approved standards.
VALID ENTRIES:
1. COMMON LANGUAGE Special Service Circuit Codes (CLCI S/S Codes) – Serial Number Format. This format is defined in the ANSI approved standard, ATIS-0300097, Structure for the Identification of Communications Connections for the Information Exchange and consists of the following elements:
1. Prefix - A non-standard code populated according to the special services circuit coding methodology of each carrier or network operator assigning the circuit identification (1-2 alpha/numeric characters).
2. Service Code - A standardized code that represents a tariff offering that requires special services circuit provisioning. Valid entries are outlined in Telcordia Technologies practice BR 795-402-100 (2 alpha/numeric characters).
3. Service Code Modifier - A standardized code that designates the jurisdiction, networking application, and additional technical information of the service identified in the service code. Valid entries are outlined in Telcordia Technologies practice BR 795-402-100 (2 alpha/numeric characters).
4. Serial Number - A serial number type code that uniquely identifies a special services circuit having the same prefix, service code, and service code modifier within a network operator or carrier assigning the circuit identification (1-6 numeric characters).
5. Suffix - A serial number type code that relates a group of special services circuits having the same service code for the same customer, and with similar termination equipment at each end (1-3 numeric characters).
6. Assigning Company ID - A standardized code that uniquely identifies the network operator or carrier assigning the circuit identification. Valid entries are outlined in Telcordia Technologies practice BR 751-100-112 (2-4 alpha characters).
7. Segment Number - A serial number type code that uniquely identifies each termination point of a special services circuit, when the circuit has more than two termination points, i.e. multi-point circuit (1 - 3 alpha/numeric characters).
USAGE: This field is conditional.
NOTE 1: Required when the ACT field on the ASR Form is “C”, “D” or “R”, otherwise optional.
DATA CHARACTERISTICS: 28 alpha/numeric characters
