Glossary
Routers are able to recognize blocks of information and evaluate addresses (as
opposed to a
➤➤
bridge , which operates with a transparent protocol). The
best paths (routes) from one point to another are chosen by using routing ta-
bles. In order to keep the routing tables up to date, routers exchange informa-
tion between themselves via routing protocols (e.g.
➤➤
OSPF ,
➤➤
RIP ).
Modern routers such as X3200 are
➤➤
multiprotocol routers and thus ca-
pable of routing several protocols (e.g. IP and IPX).
S
0
bus All ISDN sockets and the
➤➤
NTBA of an ISDN point-to-multipoint connec-
tion. All S
0
buses consist of a four-wire cable. The lines transmit digital ISDN
signals. The S
0
bus is terminated with a terminating resistor after the last ISDN
socket. The S
0
bus starts at the NTBA and can be up to 150 m long. Any ISDN
devices can be operated on this bus. However, only two devices can use the S
0
bus at any one time, as only two
➤➤
B-channels are available.

SDSL Single line
➤➤
Digital Subscriber Line
The
➤➤
upstream and
➤➤
downstream data rate is up to 768 kbps over
ranges up to 3.5 km.
The main SDSL applications are:
➤➤
E1/T1 and
➤➤
POTS .
Server A server offers services used by
➤➤
clients . Often refers to a certain comput-
er in the LAN, e.g. DHCP server.
In client-server architecture, a server is the software part that executes func-
tions for its clients, e.g.
➤➤
TFTP server . In such a case, the server is not
necessarily a computer server.
Setup Tool Menu-driven tool for the configuration of X3200 . The Setup Tool can be used as
soon as the router has been accessed (serial,
➤➤
ISDN Login ,
➤➤
LAN ).
Short hold Is the defined amount of time, after which a connection is cleared if no more
data is transmitted. Short hold can be set to static (fixed amount of time) or dy-
namic (according to charging unit).
