Spoofing
Technique for reducing data traffic (and thus saving costs), espe-
cially in WANs.
SSID
The Service Set Identifier (SSID) or Network Name refers to the
wireless network code based on IEEE 802.11.
SSL
Secure Sockets Layer A technology, now standard, developed by
Netscape, which is generally used to secure HTTP traffic between a
web browser and a web server.
STAC
Data compression procedure.
Standard connection
T-ISDN Basic Rate Interface with the performance features Inquiry/
Brokering and Telephone Number Transmission. The standard con-
nection contains three multiple subscriber numbers.
Static IP address
A fixed IP address, in contrast to a dynamic IP address.
Station guarding
Deactivation of acoustic call signalling: do not disturb.
Subaddressing
In addition to the transmission of ISDN telephone numbers, addition-
al information in the form of a subaddress can be transmitted from
the caller to the called party over the D channel when the connec-
tion is set up. Addressing that goes beyond the pure MSN, which
can be used e.g. specifically to locate several ISDN terminals that
can be reached on one telephone number for a particular service. In
the called terminal - e.g. a PC - various applications can also be ad-
dressed and in some cases executed. Costs are charged for the
performance feature, and it must be requested separately from the
network operator.
Subnet
A network scheme that divides individual logical networks into smal-
ler physical units to simplify routing.
Subnet mask
A method of splitting several IP networks into a series of subgroups
or subnetworks. The mask is a binary pattern that must match the IP
addresses in the network. 255.255.255.0 is the default subnet mask.
In this case, 254 different IP addresses can occur in a subnet, from
x.x.x.1 to x.x.x.254.
Subscriber Name
To distinguish between connections more easily, you can assign a
subscriber name for each internal subscriber.
