15 • SDH
Payload Type (sdhPayloadType1)
The payload type 1 (DS1 Level) heading is common to all three TUGs in AU-3 mapping mode, and to the sin-
gle configuration field in AU-4 mapping. The payload type indicates whether the E1 signals are asynchronous
or synchronous with respect to SDH.
•
stm1MappedAsyncE1(0)—The E1 2 Mbits signals are not synchronized to the SDH signal.
Note
Async mapping imposes no signal structure requirements, therefore a 2 Mbit
signal using this mapping doesn’t need to be framed. This mapping allows
easy interface with existing PDH systems because variable bit justification
(bits/bytes used for timing compensations) occurs as part of this mapping,
however direct access to 64kbps timeslots is not possible.
•
stm1MappedBytesincE1(1)—Byte synchronous mapping means that rate and framing of E1 signals are
synchronized to the SDH signal.
Note
Byte synchronous mapping requires G.704 framing on the E1 signals. Since
bit justification is not used, the E1 signal must be already synchronized to
the SDH network. This type of mapping allows direct access to 64kbps
timeslots, therefore it should be used for nx64kbps services.
