A digital data network carrying signaling information that interfaces with the telephone company voice/data network for services using the American National Standards Institute (ANSI) Common Channel Signaling (CCS7) protocol. Also known as CCS/SS7.
A global standard for telecommunications defined by the International Telecommunications Union (ITU). This standard defines the procedures and protocol by which network elements in the public switched telephone network ( PSTN) exchange information over a digital signaling network to effect wireless (cellular) and wireline call setup, routing and control. Signaling system 7 is an example of out-of-band CCS. (source)
