R
Radio Channel
Channel by means of which WLAN sub-
scribers and the access point of a
WLAN communicate. The radio chan-
nel must be the same within a WLAN.
You can change the radio channel for a
handset (1–14) in the WLAN settings in
the Web configurator.
RAM (Random Access Memory)
Memory in which you have reading and
storage rights. Such items as melodies
and screen pictures are stored in the
RAM after being loaded into the hand-
set via the Web configurator.
Registrar
The registrar manages the network
subscriber's current IP addresses.
When you log in with your SIP provider,
your current IP address is stored on the
registrar. This means you can also be
reached when on the move.
Remote Management
A LAN can be administered from a
computer that is not within the LAN.
Repeater
Increases the range of an access point
and therefore of a WLAN. The device
receives the radio signal from the
access point and broadcasts it further.
Roaming
Increases the range of a WLAN by
means of several access points con-
nected by an Ethernet network. Con-
nected access points have the same
SSID and the same radio channel. The
handset can switch between the access
points without breaking the connection.
ROM (Read Only Memory)
A type of memory that can only be
read, as opposed to RAM which can be
both read and written.
Router
Routes data packets within a network
and between different networks via the
quickest route. Can connect Ethernet
networks and WLAN. Can be the gate-
way to the Internet.
Routing
Routing is the transmission of data
packets to another subscriber in your
network. On its way to the recipient,
the data packet is sent from one router
to the next until it reaches its destina-
tion.
If data packets were not forwarded in
this way, a network like the Internet
would not be possible. Routing con-
nects the individual network to this glo-
bal system.
A router is a part of this system; it trans-
mits data packets both within a net-
work and from one network to the
next. Transmission of data from one
network to another is performed on the
basis of a common protocol.
RTP port
(Local) port by means of which voice
data packets are sent and received for
VoIP.
If you have received the RTP port from
your SIP provider, enter the number in
the additional SIP settings.
RTS/CTS-Threshold (request to send signal/
clear to send signal)
Signals used to control transmission in
the WLAN. If you specify an RTS/CTS
threshold value, send requests are not
answered until the threshold is reached
(threshold 1 = every send request is
answered). In heavily frequented
WLANs this can lead to network con-
gestion.
