Operation
General
A digital private network depends on two major issues:
1 Type of interworking PBX equipment
There are two different types of PBX equipment to
be connected in a private network:
a Ericsson PBXs,
ASB 150 02 or ASB 501:
- interconnection based on DSS1 (via public
ISDN or leased lines) signalling or
QSIG signalling (via leased lines)
- supporting the standard and proprietary
services and features
b other-vendor PBX:
- interconnection based on DSS1 signalling
(via public ISDN or leased lines) or
QSIG signalling (via leased lines).
- supporting the standard services and features
2 Type of network
There are two different types of interconnected
networks:
a ASB 150 02 is interconnected to other nodes via
the public switched ISDN network as a node in a
VPN:
- public ISDN signalling protocol DSS1 signalling
is used
- basic call control and supplementary services
are based on ETSI standards
- proprietary services are carried in standard
public ISDN supplementary service UUS using
the proprietary ASB 501 protocoll.
b ASB 150 02 is interconnected to other nodes via
leased lines (tie lines):
- QSIG signalling is used
- basic call control and supplementary services
are based on ECMA/ETSI standards
- proprietary services are carried in standard
public ISDN supplementary service UUS using
the proprietary ASB 501 protocoll.
Networking packages
The private digital networking functionality is packaged
and licensed.
A Networking Package license is valid for both Basic
Access and Primary Rate Access.
Protection covers services and system features.
In order to have access to the services of a given
Networking package (Standard digital Networking,
Full digital Networking), the proper FECU must always
be plugged in on the CPU-D4. The connected FECU
defines the enabled services as well as the number of
supported interface (B-channels ) used for networking
purposes.

Packages, see also
