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 It can establish the type of link to be set up, such as a one-way, two-way alternate, or two-way 520 Chapter Ten simultaneous link.
