R: Fixed Stuff bit - set to logic ‘0’ or ‘1’

C: Stuff Control bit - set to logic ‘1’ for stuff indication

S: Stuff Opportunity bit - when stuff control bit is ‘0’, stuff opportunity is I bit

O: Overhead

I: E1 payload information

The RTDM buffers the tributary synchronous payload envelope bytes of the

incoming tributaries in individual FIFOs to accommodate tributary pointer

justifications.

The RTDM performs majority voting on the tributary stuff control (C1, C2) bits. If

the majority of each set of the stuff control bits indicate a stuff operation, then the

associated stuff opportunity bit (S1, S2) will not carry T1 or E1 payload.
