Pulse dialing

interruption pulse (“clicks" in the receiver). Older procedure for transmitting
telephone numbers – also known as rotary dialing.
Redial
The last number dialed is stored in the telephone and can be dialed again
by pressing a key. This feature has to exist in the terminal device; it does
not depend on the box.
Remote administration
The possibility to change different settings of the TELES.iPBX 8TR Box
from any outside telephone using dial tones.
Ring tone
To make a differentiation between internal and external calls your
TELES.iPBX 8TR Box provides different call or ring rhythms respectively.
This helps you identify internal or external calls by the ring tone of the tele-
phone.
RJ-11
Port and matching plug for attaching analog terminal devices. Commonly
used small, rectangular, transparent plastic plug with four contact pins;
10mm x 6mm.
RJ-45
Port and matching plug that is mostly used for attaching ISDN terminal de-
vices to the ISDN NT. The plug is similar to the RJ-11-plug but is wider.
R key
The R key (also known as flash key) is a function key on your telephone. It
is usually marked by a dot or an "R". The R key lets you carry out different
functions e.g. holding and transferring. Telephones that use the pulse dial-
ing method do not have this key.
