ISDN Basic Rate In-
terface
ISDN subscriber connection. The Basic Rate Interface consists of
two B channels and one D channel. In addition to the Basic Rate In-
terface, there is the Primary Rate Interface. The interface to the sub-
scriber is provided by an So bus.
ISDN card Adapter for connecting a PC to the ISDN Basic Rate Interface. From
a technical perspective, we differentiate between active and passive
cards. Active ISDN cards have their own processor, which handles
communication operations independently of the PC processor and
therefore does not require any resources. A passive ISDN card, on
the other hand, uses the PC's resources.
ISDN Login Function of your gateway. Your gateway can be configured and ad-
ministrated remotely using ISDN Login. ISDN Login operates on
gateways in the ex works state as soon they are connected to an
ISDN connection and therefore reachable via an extension number.
ISDN number The network address of the ISDN interface, e.g. 4711.
ISDN router A router that does not have network connections but provides the
same functions between PC, ISDN and the Internet.
ISDN-BRI ISDN Basic Rate Interface
ISDN-Dynamic This performance feature requires the installation of the T-ISDN
Speedmanager. If you are surfing the Internet and use two B chan-
nels for downloading, you cannot be reached by telephone from out-
side. As a further call is signalled over the D channel, your PBX can,
depending on the setting, specifically shut down a B channel so that
you can take the call.
