What is the minimum delay through the PD Path Layer Network Emulator?
The PD breaks down a SONET signal into 2 basic sections. The first, the transport overhead, is delayed by a fixed amount, and is approximately 400 ns. The 2nd section, the payload, is analyzed to identify the various paths within the SONET signal. The various paths can be minimally delayed by 64*4*154.3ns=39.5us. Note that since all the paths are delayed by the same minimum amount, the *differential* delay for the paths is still 0.
