The Sample Rate Select switch configures the VNA’s codec’s sampling rate. The VNA’s codec can run at
either 8,000 samples per second (8 kHz), or 16,000 samples per second (16 kHz). The VNA accepts and
generates 69266-001 T1 Interface wide bandwidth page audio regardless of the setting of this switch. The
FAQ section has more information on wide bandwidth paging compatibility with the 69266-001 T1
Interface. Set the Sampling Rate Select switch according to the following table:
Open
The VNA’s codec uses 8 kHz sampling. Always use this setting if wide bandwidth paging is
disabled. This setting is recommended.
Closed
The VNA’s codec uses 16 kHz sampling.
Set the Reserved switches according to the following table:
Open Use this setting to help insure future compatibility.
Closed
Do not use this setting. Using this setting may increase the risk unexpected behavior when
upgrading the VNA.
