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).
