FACILITY DESCRIPTION
Faktaansvarig - Subject responsible
Capacity
The number of analogue connections is limited by the
number of connected ELU-A boards and the maximum
extension capacity (200).
Each ELU-A board offers 16 connection options.
Each ELU-A board has four DTMF-receivers and one
ring generator.
Limitations
In certain cases units such as modems and telephone
answering machines require ring signals of a certain
duration. Such extension positions can be
programmed so that only a single ring signal is
provided, irrespective of whether the call is external or
internal.
For analogue extensions it is not possible to enable
ringing for all individuals on the same board at the
same time. An analogue extension board (ELU-A) can
provide the ringing voltage only for one instrument at
the same time. The request for all other instruments
will be queued. In that case the ringing signal will be
multiplexed over the queued instruments. The
repetition rate of the ringing signal will go down
depending on the number of parallel ringing
instruments located on the same board.
Programming
0122
Long ring bursts
With this command it can be specified that the
analogue extension position shall always supply long
ring signals (bursts), e.g. for modems.
NOTE: The command also affects ring signals to
digital extension positions
xxxx Enter the extension's directory number of
the extension
z Enter the relevant function.
N = Normal ringing (default data).
Y = Long ring bursts only.
0124
Call waiting tone ?
Busy extensions that are connected via the ELU-A
board can hear call waiting tone when a new call is
camped on.
xxxx Enter the directory number of the
extension.
z Enter the relevant function.
N = No call waiting tone (default data).
Y = Call waiting tone
