| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. he ISDN User Part
or ISUP is part of the Signaling System #7 which is used to set up
telephone calls in Public Switched Telephone Networks. It is specified
by the ITU-T as part of the Q.76x series, ANSI (T1.113-YEAR) and
Telcordia Technologies formerly Bellcore Generic Requirements document
GR-246-CORE. When a telephone call is set up from one subscriber to
another, many telephone exchanges will be involved, possibly across
international boundaries. To allow a call to be set up correctly, where
ISUP is supported, a switch will signal call-related information like
called or calling party number to the next switch in the network using
ISUP messages. |
