Direct Call
You are not at home. However, there is someone at home who
needs to be able to reach you quickly and easily by telephone if ne-
cessary (e.g. children or grandparents). As you can set up the Direct
Call function for one or more telephones, the receiver of the tele-
phone simply needs to be lifted. After five seconds, the PBX auto-
matically calls the defined direct call number, if you do not start dial-
ling another number first. You can enter up to 12 destination num-
bers when you configure Direct Call. A direct call number can only
be used by one subscriber. If you want to change an entered direct
call number, you can simply enter the new direct call number without
having to delete the old direct call number. The old number is auto-
matically overwritten when the new configuration is transferred to
the PBX.
DISA
Direct Inward System Access
Download
Data transfer during online connections, where files are "loaded"
from a PC or data network server to the user's own PC, PBX or ter-
minal, so that they can be used there.
DSL and ISDN con-
Data is transferred between the Internet and your PBX over ISDN or
nections
T-DSL. The PBX determines the remote terminal to which a data
packet is to be sent. For a connection to be selected and set up,
parameters must be defined for all the required connections. These
parameters are stored in lists which together permit the right con-
nection to be set up. The PBX uses the PPP (Point-to-Point Pro-
tocol) for ISDN access, and PPPoE (Point-to-Point Protocol over
Ethernet) for access over T-DSL. The traffic on these two Internet
connections is monitored separately by the PBX.
DSL modem
Special modem for data transmission using DSL access technology.
DSL splitter
A DSL splitter is a device that splits the data or frequencies of vari-
ous applications that run via a subscriber line or distribution point,
and provides this via separate connections.
Services
Euro ISDN contains service indicates with defined names. Some of
these have only historical meaning. In general, you should choose
the "Telephony" service for "real" telephone calls. If this selection
does not work (depends on network operator), you can try "speech",
"audio 3k1Hz" or "telephony 3k1Hz". The same applies for faxing.
Here, too, there is the collective term "Fax" plus a couple of more
specific cases. From a purely technical point of view, the services
are bits in a data word evaluated by means of a mask. If you include
several bits in the mask, all these services are approved for activa-
tion, while in the case of just one bit, it is just the one selected ser-
