Line Digital Signal Processing Device and Method

摘要

A line digital signal processing device and method. The device includes at least two line accessors and a data processor, where the at least two line accessors are connected to the data processor and each line accessor is not provided with line digital signal processing, and the data processor simultaneously performs line digital signal processing and service data recovery on service data sent by the at least two line accessors, thereby reducing complexity of an access device, and monitoring, maintenance, and alarming are simultaneously performed on complex line digital signal processing components.

1. A line digital signal processing device, comprising:
at least two line accessors; and a data processor, wherein the at least two line accessors are connected to the data processor, wherein the at least two line accessors are configured to:
provide interface protection;perform analog signal processing;perform analog-to-digital conversion;perform service scheduling on received service data; andsend the processed received service data to the data processor after the received service data undergoes analog signal processing, analog-to-digital conversion, and service scheduling, wherein the data processor comprises:
a first data encapsulater;a first line digital signal processor connected to the first data encapsulater;a first service scheduler and forwarder connected to the first line digital signal processor;a first exchanging/forwarding controller connected to the first service scheduler and forwarder; anda first upstreamer connected to the first exchanging/forwarding controller,wherein the first data encapsulater is configured to:
receive the service data sent by the at least two line accessors;encapsulate the received service data; andsend the encapsulated service data to the first line digital signal processor,wherein the received service data comprises service data of different access modes,wherein the first line digital signal processor is configured to:
perform line digital signal processing and service data recovery on the encapsulated service data; andsend the processed service data to the first service scheduler and forwarder,wherein different line digital signal processing methods are used for the service data of different access modes,wherein the first service scheduler and forwarder is configured to:
perform service scheduling on the processed service data; andforward the service data obtained after service scheduling to the first exchanging/forwarding controller,wherein the first exchanging/forwarding controller is configured to forward the service data obtained after the service scheduling to the first upstreamer, andwherein the first upstreamer is configured to send, in an upstream direction, the service data obtained after the service scheduling.
