5.6 Networking Capabilities
Networking means to provide all services over network links to other
entities of the Private Telephone Network (PTN). This cuts costs
compared to the TDM-based leased line. Furthermore, it simplifies
Branch Office scenarios to better fit the data network model with
IP-connected Branch Offices.
To supply basic and supplementary services transparently, ISDN
signaling over the Q-reference point (QSIG) is implemented over H.323
in IP networks. This makes networked PBXs possible over IP intranets
and also over the Internet with the appropriate protection. The
intra-connectivity over (private) ISDN is in accordance with ITU-T QSIG
for E1/T1. Apart from QSIG, proprietary intra-connectivity is supported
for the US market. MX-ONE supports both E1 and T1. The realization of
the networking functionality in MX-ONE is implemented in the MX-ONE
Telephony System.
Third-party products and VoIP service providers can also interoperate
with MX-ONE using SIP signaling, for basic services such as basic call,
caller ID or name, and DTMF digit signaling and supplementary generic
services like parking, transfer, and conference.

NETWORKING.
