ABSTRACT:
An office point is connected to a central office using a plurality of basic rate interface (BRI) lines. A physical layer of the office point provides connection to the BRI lines. A second layer uses a first table for accessing terminal endpoint identifiers (TEIs) using port numbers and logical link numbers. A third layer uses a second table for accessing logical terminal number using the port numbers and the logical link numbers. The third layer also uses a third table for using logical terminal numbers to access service profile identifiers.
