Part 1 System Interfaces 69
Fig. 1.11: S user-network interface
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 interface S:
• The "V2" mode is used to operate the PC Operator Office 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 424.
• With the "EXTERNS" 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 "Basic Access S External", page 61).
Format of the ETSI S-bus
The format on the ETSI S-bus can be configured in the interface configuration for
each S interface.
