Rate Adapter Option
8-2 DDS/MR64
RATE ADAPTER CONFIGURATION OPTIONS
Most options available for the non-rate adapter option are available for
the rate adapter option. Configuration options which are different for the
rate adapter option include the following:
Timing
If the rate adapter option is running rate adapted 19200 bps or 9600 bps,
the standard timing options are not used. Timing options are as follows:
NET TIME - Network transmitter timing can be slaved to either:
•
DDS - Received data timing for normal operation.
•
INTERNAL - Timing for limited distance modem operation.
•
DATA TIME - The rate adapter circuitry can be slaved to either:
•
INTERNAL - Timing for normal operation.
•
EXTERNAL - DTE provided timing.
Rate
This option is the same as for the non-rate adapter option except that
while the rate adapter is enabled, the only options available are 64 kbps,
56 kbps, and 2.4 kbps. If the asynchronous and rate adapter options are
enabled, this menu is skipped and the line rate is set for 2400 bps (rate
adapted asynchronous 1200 bps).
