2.13 Sample Rate Selection Command
The 73M1x66B device can operate in one of two sample rates – 8 kHz or 16 kHz sample rate. The
device defaults to 8 kHz operation upon startup and can be changed to run at 16 kHz using this
command.
Notes: Changing of PCM sample rate will affect the followings:
1. Data presented in PCM timeslots - reallocation of transmit and receive timeslots may be
necessary or required to properly communicate with peer interface.
2. Barrier interface operation - a momentarily lost of synchronization on the barrier interface is
expected. However, the driver will automatically attempt to recover barrier synchronization. The
SYNC lost event is sent and should be followed by SYNC restored event when the barrier is
synced up again.
Syntax
