DATA RATE

(most significant bits)

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)

LPBK

These two bits set the loopback mode:

No loopback; normal operation

Activates local (payload) loopback (near end)

Activates equipment loopback

Activates remote loopback

B00000000

56K

Set to 64 kbps per time slot

Set to 56 kbps per time slot

B00000000

↑

BUFF

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)

B00000000

↑↑

TX MODE

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

B00000000

----

RX ON

Set to turn the receive side of the module off

Set to turn the receive side of the module on

B00000000

↑↑↑

------

Not used. These positions must be set to 0.

* 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.
