Conventions and Notation
Throughout this document, SDH and SONET terminology are used interchangeably when describing portions
of the payload or overhead of a SONET/SDH frame. SDH terminology provides more “granularity” for describ-
ing parts of a frame and hence is used more often.
The use of overbars, for example DDEL_OUT, designates signals that are active low.
Notation for bit encoding is as follows:
• Hexadecimal values are followed by H. For example: 0B00 H.
• Binary values in text are either spelled out (zero and one) or appear in quotation marks followed by b.
For example: ‘10101’b.
• Binary values in the Default and Description columns of the register sections have no special marking,
but are isolated from text as in this example:
0: No action on read access
1: Auto-reset interrupt request register upon read access
