Engineering Common Channel Signaling Networks for ISDN

Common Channel Signaling (CCS) is an integral component of ISDN, and properly engineered networks will be critical for the provision of ISDN services. With the introduction of ISDN, signaling networks will be expected to support a wide range of message types, and this can have a significant effect on signaling link performance. One of the major effects that ISDN will have on the signaling network is that User-to-User Information (UUI) will be transported either in ISDN User Part (ISDN-UP) messages or as separate messages on temporary or permanent signaling connections.
