9.2. POTS modes
9.2.1. Hybrid / Codec Mode
The hybrid mode or the codec mode is selected by the menu “ANALOG MODE”. If
you select Hybrid parameter, you select the phone mode.
The change of the initial mode can’t be done during the communication.
When the high speed connection is broken the Scoop E-Z doesn't fall back to the regular
POTS mode (3.4 kHz). The voice communication is interrupted and a new call has to be
made.
9.3. Network parameters
9.3.1. Setting the optimal rate
The Scoop E-Z with the lowest max line speed setting will determine the maximum
connect rate.
a) When the speed mode function is set on "Automatic" adaptation ( general reset
Configuration. ) both modems will negotiate the highest transmission rate
according to the quality of their current respective networks.
This rate is also limited at the lowest speed of the two max speed selected on the 2
units.
If the line quality is changing during the audio-transmission the modems will try to
adapt consequently the data rate by fall back at a lower data rate and fall forward
to the higher selected speed. During each re-negotiation the audio signal may be
interrupted. If these "break down" appear, it is highly recommended to set the max
line speed selection of one of the Scoop E-Z at one level or two below the used
connect rate.
