SIP User (SIP account)
User account which has been cre
-
ated with a VoIP provider and
contains the required access and
operating data of a VoIP telephony
connection of a VoIP telephone con
-
nection and is linked to an associ
-
ated call number. The login data of
the user account can be created in
the Access server as SIP provider in
order to log the Access server onto
the VoIP telephony connection of
a VoIP provider by means of the
session initiation protocol (SIP) via
the Internet, and thereby be able to
make telephone calls.

Storey call button
The storey call button (ERT) is used
to call from a storey door to the
indoor device. This can be connected
as standard on all Access indoor
stations via the right-hand R45 jack
(switching input E1 – terminal 3,6)
of the indoor station and addition
-
ally configured via the administration
interface of the Access system.
Switch
Central coupling element and distri
-
bution component which links indi
-
vidual network components to an
IP-based network and is responsible
for forwarding data traffic within the
IP-based network (also called a net-
work switch or distributor). Switches
come in a variety of hardware-based
designs with different equipment
versions relating to the range of
functions and the security functions.
TCP – Transmission Control net
-
work Protocol
Transport protocol for data traffic
between network-capable devices
(servers, computers, etc.) in IP-based
networks. TCP is used for packet-
based data transfer in almost all
operating systems and is part of the
IP protocol for the Internet. For bidi
-
rectional data traffic, there must be
a connection between the devices.
TCP includes:
• Transport service
• End-to-end control (reliable data
transfer)
• Connection management
• Data flow and time control
• Multiplexing connections
• Error handling
Telecom socket RJ45 8/8
Standardised connection unit for
network cabling with two eight-pin
RJ45 jacks for correct connection of
Access indoor stations.
The left-hand jack is used for the
LAN network. The storey call button
and if applicable the customer’s own
existing signalling device are con
-
nected using the right-hand jack.
TP – Twisted Pair
A TP cable (TP) is a symmetrical
copper cable used for data transfer,
which consists of two cores (1 core
pair) which are twisted around
one another. In IP-based networks,
cables with four core pairs are
normally used. The data transfer
takes place in a single direction per
core pair. For a data connection 2
core pairs are required (sending and
receiving). In the case of higher data
transfer standards (e.g. 1000 BASE-T
Ethernet) all 4 core pairs are used (2x
sending and 2x receiving). TP cables
come in various unshielded and
shielded designs, each with different
core diameters. The performance
capability of a TP cable is specified
by its category (e.g. Cat 5).
