Cause, be the necessary condition of ASON carrying optical-fiber longitudinal difference relay protection business.
When passage is in stable state, can be by NMS（Hereinafter referred to as webmaster）Check in ASON equipment
Interconnection, so as to judge whether ASON passages transceiver path consistent.But, when ASON routing restorations and return moment, by
Change rapidly within ms grades of time period in the state of ASON equipment interconnections, cannot be checked by webmaster, therefore do not have at present
There is the whether consistent method of test ASON passages transceiver path.In view of the use that ASON equipment has at present is first built rear form removal formula, is had
Use first tear the formula that models afterwards open, and optical-fiber longitudinal difference protection business does not allow passage transceiver path moment inconsistent, therefore passes through
Test checking ASON routing restorations and return instant channel transceiver path uniformity are necessary.
