    • A router (101, 103, 105) includes a communication interface, for receiving a packet (107a-107f), when connected to a communication network. The router (101, 103, 105), for example with a processor, for calculating an alternate path for routing a packet (107a-107f) received from the communication interface while awaiting a determination that a pre-determined path for the packet has failed. According to one or more embodiments, the router (101, 103, 105) can facilitate calculating an alternate path for routing the packet (107a-107f) received from the communication interface while awaiting a first determination that a pre-determined path for the packet has failed and/or a second determination that the pre-determined path is likely to fail. Further in accordance with one or more embodiments, the router (101, 103, 105) can predict a behavior of network element(s) in a route topology, wherein the network element(s) is included in a pre-determined path for routing the packet received from the communication interface.

    • 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).
