• Power-saving mode introduces delays.
For operations involving real-time communications, we recommend
that the power-saving mode be disabled. For operations using protocols
for file transfer, etc., also disable the power-saving mode or set the
HOLD mode interval that does not affect those transfer protocols.
Otherwise, delays of data may cause protocol errors, resulting in
communications errors.
•
Note that the other end can also automatically enter HOLD mode
during the HOLD mode interval, and that this end has no means to
force it out of that mode.
•
If the other end does not support the HOLD mode, there is no
transition.
