The figure below shows a simplified diagram of a CPN- and BN-to-host
arrangement. The ISDN Gateway is a UNIX or MSDOS computer connected to
the switch on one side and to a host computer on the other side. The connection to
the switch is over a synchronous interface with BX.25 protocol.

Private network services
In addition to providing access to switched-public networks, ISDN provides
private-network services by connecting Avaya MultiVantage in an ETN, DCS, or
QSIG Network. This gives you more efficient private networks that support new
integrated voice and data services. ETN, DCS, and QSIG networking services are
provided as follows.
ETN services
Avaya Media Servers that function as tandem nodes in an ETN can be
interconnected using DS1 trunking facilities with ISDN. All signaling between
the tandem switches is done with ISDN D-channel and normal ISDN protocol.
