Recommendation G.826 was derived to prepare for broadband services. Specifically, SONET/SDH equipment should now offer a higher quality of service than previous PDH equipment. PDH equipment might have difficulty in meeting the new standard, but some latitude for exemption is acknowledged during the transition from PDH to SDH/SONET. The transition to a block-error-based measurement from the more familiar BER will no doubt take a long time , source: An evaluation of the Northway emergency telephone system http://tiny-themovie.com/ebooks/an-evaluation-of-the-northway-emergency-telephone-system.

Connection to the ring is made by either a single or dual node. Single nodes are attached to the ring via a concentrator, whereas a dual node can be attached directly to the ring. The concentrators and dual nodes require a bypassing facility so that the rings are unaffected by their presence when they are not transmitting or receiving.
