Features
The T-Comfort 930 DSL is a communications system for integrated voice and data communication. The out-
standing feature of this communications system is its modular structure:
■
Even with the smallest T-Comfort 930 DSL version, it is possible to use all the most important communi-
cations applications. The basic module enables telephony with system telephones, ISDN telephones and
analogue terminals, Internet / intranet data communication, CTI applications, sub-system operation and
system configuration using a standard Web browser.
The expansion module of the T-Comfort 930 DSL provides three slots for further interface cards. Using
different combinations of interface cards, the configuration of the T-Comfort 930 DSL can be tailored ex-
actly to your communications requirements. The need for additional U
pn
ports supporting DECT, further
S
0
ports or more a/b ports can be met using one or more interface cards without changing the system.
■
The base module of the T-Comfort 930 DSL’s version 1can be expanded to connect an door entrance
intercom and a serial interface. For a T-Comfort 930 DSL version 2 we recommend to connect a Doorline
entrance intercom (see Intercom System (for a/b) starting on page 42).
■
You can use an additional insertable memory card (CompactFlash) to operate further program packages.
■
Another special interface card provides an internal U-R2 compatible T-DSL modem. Additional infor-
mation can be found in the corresponding user manual of the DSL modem.
Cascading
Using the expansion module, the T-Comfort 930 DSL can be cascaded with a second T-Comfort 930 DSL
communications system.
Telephony
The T-Comfort 930 DSL communications system is designed to be connected to an ISDN basic access using
the DSS1 protocol. System access (point-to-point) and multi-terminal access (point-to-multipoint) are both
supported. The two forms of access can be configured in parallel.
For this purpose
■
the T-Comfort 930 DSL basic module includes two S
0
ports (one external one and one that can be
switched between internal/external),
