Private Circuit Switched Voice Networking
Private voice networks are built using structured leased line circuits (E1 or T1) or by establishing permanently
connected 'B' channels over ISDN circuits between IP Office systems. Each channel within the E1 or T1
interface can provide a single voice or 64K/56K data call. Where leased line circuits are used within a private
networking scenario, these E1 or T1 interfaces are typically configured to use QSIG signaling between sites.

QSIG provides a level of voice feature transparency between PBXs and is the favored signaling standard within
multiple vendor and international voice networks. The IP Office E1 or T1 module terminates a QSIG connection
with a 120 ohm RJ45 interface.
