The Receive Port B Remote Status and Alarms register contains information on the status of the far-end device,

which is connected to Port B. On a local Loss of Signal on Port B, LLOSB alarm, these bits return to their reset

values. When set, the RBRLOSA, RBRLOSB, RBRBA, and RBRDSLL bits will raise an interrupt if the

corresponding interrupt enable is set. Also, a change in value on RBRLOSA, RBRLOSB, RBRDSLL or RBRBA

will set the RBRCS bit. When set, the RBRCS bit will raise an interrupt if the corresponding interrupt enable is

set.
