System Interfaces
1.19
3.1.3 Analogue Network Interfaces
The analogue network interfaces support DTMF and pulse dialling.
3.2
User-Network Interfaces
The PBX supports digital and analogue user-network interfaces.
3.2.1 Digital User-Network Interfaces S and AD2
On each of these interfaces several appropriate terminals can be hooked up and
powered simultaneously.
Each of these interfaces has two 64 kbit/s user information channels and one 16
kbit/s control and signalling channel (2B+D). This makes it possible to establish
two independent call or data connections simultaneously.
S User-Network Interface
The S user-network interface is a digital 4-wire interface used for connecting sys-
tem terminals, ISDN terminals, Terminal Adapters and ISDN PC cards. The PC
Operator is connected via a special Terminal Adapter.
