ABSTRACT:
A fiber-optic communications interface (110) and method of operation that operates with a paired fiber-optic communications interface (112) in a redundant communications termination point (101). The fiber-optic communications interface (110) has a paired card interface (122) that exchanges at least a first subset of status data between a local bearer processor (124) and a paired bearer processor (144) located within a different card cage (112). The local bearer processor (124) processes bearer data channels communicating with a remote site (102) through a remote site fiber-optic line (106). A local data interface (128) exchanges data contained in the bearer data channels between the local bearer processor (124) and a local user data network (114). The local data interface (128) also exchanges at least a second subset of the status data with the paired bearer processor (144) through the local user data network (114).
