Channel B – 1 = NRZI

0 = NRZ

Channel B – 1 = Full Duplex

0 = Half Duplex

Channel B – 1 = Synchronous

0 = Asynchronous

Channel A Baud Rate
(Bit 4 is MSB)

Channel B – 1 = Available

0 = Not Available

Channel A – 1 = NRZI

0 = NRZ

Channel A – 1 = Full Duplex

0 = Half Duplex

Channel A – 1 = Synchronous

0 = Asynchronous

NOTE

The Local Line interface will always be NRZI and
asynchronous regardless of the values in Option–01
or the dipswitch settings. When configuring the
channels, they must be either both synchronous or
both asynchronous. You cannot run synchronous on
one channel and asynchronous on the other.
