QSIG

B Private Networking

QSIG

QSIG is the generic name for a family of signaling protocols. The Q reference point or interface is the logical point where signaling is passed between two switches in a private network. QSIG signaling allows certain features to work in a single-vendor or multi-vendor network. QSIG complies with the International Organization for Standardization (ISO) Integrated Services Digital Network (ISDN) private-networking specifications. QSIG is defined by ISO as the worldwide standard for private networks. QSIG uses ISO standard protocols as well as call independent signaling connections (CISCs), administered as non-call-associated temporary signal (NCA-TSCs).

DEFINITY ECS provides six levels of QSIG functionality (each level is turned on or off on page 6 of the Customer Options screen):
