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.

IP Office supports the following QSIG services across this network:

· Simple Telephony Call/Basic Call: ETS300 171/172.

· Circuit Switched Data Call/Basic Call: ETS300 171/172.

· Called/Calling Line ID Presentation: ETS300 173.

· Called/Calling Name Presentation: (SS-CNIP, SS-CONP, SS-CNIR) ETS300 237/238.

· Message Waiting: (SS-MWI) EN301 260/255.

· Transfer: (SS-CT) ETS 300 260/261.
