AppendixIIITransmissioncapacityoftheNetworkAdapter Abstract
Gives requirements for an equipment known as 'SDH network adapter' for transporting MPEG-2 signals over SDH networks. Covers necessary operations for adapting the MPEG-2 transport streams into a STM-1 or sub-STM-1 frame, and functional characteristics associated with this equipment.
