* These values are the only legal ones for setting the parameters. Any parameter set to a value
outside its specified range produces an unpredictable result.
† These test modes also verify the same pattern if any loopback is active at the time.

DS-64NC Synchronous Data Module
Set the two most significant digits of the binary value for the
desired data rate, divided by 2000. (From left to right, these
digits correspond to S4, positions 1 & 2; Section 2.7.6)

These two bits set the loopback mode:
No loopback; normal operation
Activates local (payload) loopback (near end)
Activates equipment loopback
Activates remote loopback
Set to 64 kbps per time slot
Set to 56 kbps per time slot
Set starting depth for transmit and receive buffers to 256 bits
(for synchronous operation)
Set starting depth for transmit and receive buffers to 6000 bits
(for plesiochronous operation)
These two bits set the transmit mode:
Transmit side off at all times
Transmit side operates only when CS (Clear-to-Send) is asserted
(polling mode)
Transmit side operates at all times; RS (Request to Send)/CS
handshake is operational
Transmit side operates at all times; CS forced on
Set to turn the receive side of the module off
Set to turn the receive side of the module on
Not used. These positions must be set to 0.
