Abstract

TRANSPARENT COMMUNICATION OF CONTROL
INFORMATION THROUGH A SWITCHING NETWORK
Abstract An apparatus for establishing a flexible rate interface (FRI) link on a standard ISDN link. The FRI link has its own signaling channel that is distinct from the signaling channel of the standard ISDN link, and the signaling channel of the FRI
link is transparent to intervening switching systems. There are no geographical restrictions on a FRI link. The signaling channel of a FRI link may be established by designating a B channel of a standard link, by using a logical link of a D channel of a standard ISDN link, or by using standard ISDN user information transport facilities to communicate the signaling channel. FRI transport channels are B channels of astandard ISDN link or subchannels of a B channel.
