Set the T1 Synchronous switch according to the following table:

Open	The VNA is frequency locked to the received T1 signal. This setting is ignored if the VNA is
	both a ST-Bus Clock Slave and a T1 Clock Slave.
Closed	The VNA is not frequency locked to the received T1 signal. “Elastic store” buffers in the T1
	transceiver integrated circuit either duplicate or drop a frame as needed.

Set the E1 Select switch according to the following table:

Open	The VNA uses T1 signaling.
Closed	The VNA uses E1 signaling. NOTE: Upon initial release of the VNA, this feature does not
	function properly.

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. 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 of unexpected behavior when
	upgrading the VNA.
