ABSTRACT: This Technical Reference (TR) presents the view of Telcordia on generic requirements for operations gateway functions that interwork
the Integrated Services Digital Network (ISDN) Basic Rate Access (BRA) operations interfaces. The ISDN operations interfaces
interworked via operations gateway functions include the Operations Systems/Network Element (OS/NE) interface, Digital Subscriber Line
(DSL) embedded operations channel (EOC), and the Integrated Digital Loop Carrier Embedded Operations Channel (IDLC EOC).
