2 System interfaces
This chapter features the different types of digital and analogue network and termi-
nal interfaces and points out a number of configuration particularities. The chapter
ends with special interfaces for door intercoms and general bells.
Tab. 1 System interfaces and channels
Term Explanation
B channel User information channel: Each connection occupies one user information
channel, e.g. 2 user information channels (connections) can be occupied
simultaneously using one basic access.
D channel Control and signalling channel: Channel for control and signalling as well as
for packet data transfer.
2B+D / 30B+D 2 B channels and 1D channel / 30B channels and 1D channel
Ports Physical connection points on the communication server for network inter-
faces and terminal interfaces
Network interfaces Network-side connection possibilities for the communication server
• Basic rate interface BRI-T Digital network interface 2B+D
• Basic rate interface BRI-S
external Digital network interface 2B+D:
A terminal interface S configured as BRI-S external.
• Primary rate interface PRI Digital network interface 30B+D
1)
1)
CAS (channel-associated signalling) is also used in some countries (e.g. Brazil).
• SIP access via the Ethernet inter-
face on the basic system
For connection to one or more SIP providers. An SIP access contains a max-
imum of 30 channels.
• Analogue network interface
(FXO network interface)
An analogue network connection has 1 user information channel.
Terminal interfaces Terminal-side connection possibilities for the communication server
• ISDN terminal interface
(Terminal interface BRI-S)
Digital terminal interface 2B+D:
Connection for Euro ISDN terminals, Terminal Adapters and ISDN PC cards.
• Digital user-network interfaces
(DSI terminal interface)
A maximum of 2 digital system phones or one DECT radio unit can be oper-
ated on a proprietary DSI bus.
• IP terminal interface
(via Ethernet Interface)
Digital terminal interface for linking up IP system phones and SIP phones
(softphones and desk phones).
• Analogue terminal interfaces
(FXS terminal interface)
An analogue terminal connection has 1 user information channel.
Special interfaces Other connection possibilities for the communication server
• Ethernet interface on the basic sys-
tem
Central interface for connecting WebAdmin, a CTI server, IP system phones,
SIP terminals, for the network-side connection to an SIP service provider, or
to implement a private network, etc.
• Door Intercom Systems Special interface for connecting door intercom systems
• General Bell Special interface for general bell
