Appeal No. 1998-0291
Application 08/360,894
The invention relates to an architecture for
telecommunications networks comprising Asynchronous Transfer
Mode (ATM) switches interfacing with networks comprising
Synchronous Transfer Mode (STM) switches. Signaling
information received from an STM switch via in-band signaling
is supplied to an ATM switch that will route the associated
call to its intended destination by converting the signaling
information to a form suitable for transmission to the ATM
switch via an out-of-band signaling network. Signaling System
7 (SS7), an out-of-band type signaling, is used to convert in-
band STM signaling to out-of-band STM signaling. A terminal
adapter translates STM protocols to ATM protocols.
Representative independent claim 10 is reproduced as
follows:
10. A method of interfacing an ATM switch of an ATM
network with an STM switch that employs in-band signaling to
transmit telephone-call signaling information to said ATM
switch, said ATM switch interfacing with an out-of-band
signaling network for the purpose of receiving signaling
information, said method comprising the steps of
interfacing said in-band signaling when it is
received from said STM switch with said out-of-band signaling
network, and
