Note the following:
•
With SDC Option Set 2 selected (for Raymar-Telenetics, Motorola, non-
Raymar-Telenetics, and non-Motorola DSU/CSUs), the DSUs’ restoral
configuration should be set to
Timing
=Internal.
•
In this case, the 326X
FAST
-SDC
DTE Rate
must be set to a constant rate as
provided by the network (defaults of 56/64 kbps).
•
Enable Option Set 2 in both the local and remote modems, and ensure that
Mode
(AT
*
SM) is set
the same
in both modems.
•
The SDC modem supports single channel environments only. For example, the
SDC modem can restore Port 1
only
of the 35XX device.
•
The 35XX device, when initiating restoral, must be set to Normal mode (as the
35XX network management channel is virtually a time division multiplexed
data stream which cannot be compressed with the SDC product).
•
The SDC modem may have the ARS feature enabled. In this case, ARS
determines the link rate.
