1.27.2.1 QSIG Network—OVERVIEW
Description
TIE line service can be used on a private network that is established using ISDN (PRI) lines programmed
to implement the QSIG protocol (Q.931). QSIG offers TIE line service as well as advanced caller and called
party identification features.
When configuring Panasonic Hybrid IP-PBXs to establish a private network based on QSIG, the ports of
each PBX must be programmed so that each ISDN line has a "master" connection and a "slave" connection.
