Electronics

  • Abbreviation of Signaling system #An ITU-defined protocol that is utilized to set-up, manage, and terminate telephone calls. SS7 uses out-of-band signaling, so control signals, such as those required to provide services such as call set-up, call forwarding, roaming, toll-free dialing, caller ID, and call termination, use a dedicated channel other than that transmitting the voice signals, providing for a more efficient, secure, and flexible arrangement. In addition, SS7 handles other tasks such as the verification that a given number can access given features, in addition to determining the routing of calls. Also called SS7 protocol.
