The meaning of the 12-position DIP Switch settings are shown in Figure 4-2 and de-
scribed as follows:
Switch positions 1 - 2 select the LBO setting from 0 to -22.5 dB.
Switch positions 3 - 4 select the Framing Mode of ANSI, AT&T, or SF.
Switch position 5 selects the coding method B8ZS or AMI.
Switch position 6 selects whether the Tx data input is aligned with the DCE-supplied
clock, or the DTE-supplied clock.
Switch position 7 selects Frame Relay or Transparent (Clear Channel) mode.
Switch positions 8 - 12 are reserved for future use and should remain off.
