Summary

This Recommendation describes a flexible optical fibre access network capable of supporting the bandwidth requirements of ISDN and B-ISDN services. This Recommendation describes systems with nominal symmetrical line rates of 155.520 Mbit/s and asymmetrical line rates of 155.520 Mbit/s upstream and 622.080 Mbit/s downstream. This Recommendation proposes the physical layer requirements and specifications for the physical media dependent layer, the TC layer and the ranging protocol of an ATM-based Passive Optical Network (ATM-PON)
