data path. Transmit attenuation
is selectable. Default: O dB
Pulse Shape

0 to 40 Meters
40 to 81 m
81 to 122 m
122 to 162 m
162 to 200 m
Refers to length of cable
between MultiVOIP and
PBX/telco in meters. Most
common will be 0 to 40m.

Detect Flash
Hook
Y/N This setting determines whether
or not the MultiVOIP responds
to hook-flash signals.
Detection Time 100 – 1500
milliseconds
Minimum hook-flash time that
will be interpreted as a valid
flash by the MultiVOIP.
Generation
Time
100 – 1500
milliseconds
In some systems, a MultiVOIP
might receive a hook-flash signal
from an upstream device (a PBX,
voip or other device) and must
replicate it to a downstream device.
This parameter determines the
duration of the hook-flash signal
that is passed to a downstream
device.
Clocking External/Internal Set opposite to telco/PBX setting.
Example: if telco clocking internal,
set VOIP clocking as external.
