System Interfaces
HBT_20321104_01/B0_en
Up to 8 terminals can be operated on an S user-network interface. They are
addressed with the single-digit terminal selection digit (TSD).
There are three available modes ("S bus protocol" setting in the interface config-
uration) for operating the interfaces:
• The "V2" mode is used to operate the PC OperatorOffice 1550 and the paging
system.
• The "ETSI" mode is used to operate ISDN terminals, Terminal Adapters and
ISDN PC cards.
For the ISDN services supported, see "ISDN Services Supported by the System",
Page 2.291.
• With the "external" mode an S interface can be used as a basic access S for
private networking with QSIG / PSS1 or DSS1. It is then no longer available as
a user-network interface (see Page 1.13).
AD2 User-Network Interfaces
The AD2 digital user-network interface is a proprietary, system-specific 2-wire
interface used for connecting system terminals:
• Corded system terminals
• V.24 interface Pocket Adapter
• Ascotel DECT radio units
Fig. 1.12:
AD2 user-network interfaces
Two system terminals can be connected to an AD2 user-network interface.
Address allocation is done by means of a switch on the terminal.
