The specification of interface compatibility requirements for carrier-
35、to-carri- er interfaces was initiated under the auspices of the Accredited Standards Committee on Telecommunications, Tl . The purpose of this standard is to enable separate telecommunications entities to provide compatible interconnecting equipment and signaling. To accomplish this purpose, this st
36、andard provides signaling protocol requirements for an exchange-interexchange (E-l) interface that intercon- nects a switching system in an exchange carrier (EC) network with a switching system in an interexchange carrier (IC), international carrier (INC), or consolidated carrier network. The E-l in
37、terface is at a point of ter- mination (POT) between the two switching systems. It is expected that the telecommunications industry will combine protocols, or parts of protocols, from this standard to provide telecommunications ser- vices. At the time of this writing, some protocols are included in
38、(1) EC-to- IC access services generally known as Feature Groups C and D Switched Access Services, and (2) IC-to-EC access services known as Feature Groups B, C, and D Switched Access Services. There is one annex in this standard. Annex A is informative and is not con- sidered part of this standard.
