3.5 Service channel configuration settings (S1, S2)
Factory setting : 0 0 0 0 0 0 0 0 1 0 1 0 0 1 1 0
SerIn
: Method of handling the inbound 24 bit low speed signaling data
OFF – 24 signaling bits are taken from the parallel input
*
ON – 24 signaling bits are taken from the serial input
RefClkSel
: Reference Closk Source selection for the ADPCM PLL
OFF – data channel receive clock (RXC)
*
ON – data channel transmit clock (TXC)
LocalLoop
: Local Loop Mode selection
OFF – Normal mode
*
ON – Test mode
ClkMaster
: Receive and Transmit clock source
OFF – Normal Mode (incoming RXC and TXC)
*
ON – Test Mode (internal RXC and TXC)
Init_on_Error
: behavior of the signaling bits on ERROR condition
OFF – all bits keep their previous state
*
ON – all bits become inactive
RemoteControl
: RS-232 configuration mode
OFF – configuration through S1,S2 switches
*
ON – configuration through the internal control bus (future extension)
