The C2, F2, Z3, Z4 and Z5 bytes are debounced. This function provides the means for detecting and reporting
persistent changes that occur. The debouncing operation is identical to the TOH Debouncing Mechanism. The
interstitial and debounced value locations are given in Table 13. Any byte that is received with a new value and
that new value is constant for three consecutive frames, will cause the indicator RPNEW (SR1; 0F2/3/5[H], Bit
5) to be set to "1".
Rx POH Alarm Processing
At present, the only Path level alarm that is defined is Path RDI. The mechanism that is implemented is the
new Three Bit RDI-P format. This format is compatible with previous equipment (One Bit RDI-P - old Path Yel-
low) and the new Four State RDI-P. The Three Bit PRDI FORMAT uses bits 5, 6 and 7 of the G1 Byte. The cod-
ing is shown in Table 14. Four Status Bits are used to report Path RDI. These are RRDI-P (SR1; 0F2/3/5[H], Bit
4), RRDI-PSD (SR6; 0EA/B/D[H], Bit 7), RRDI-PCD (SR6; 0EA/B/D[H], Bit 6) and RRDI-PPD (SR6;
0EA/B/D[H], Bit 5). The first represents codes that are received only from old equipment. The latter three are
used to identify new equipment. PRDISEL (CR16; 0FF[H], Bit 6) is used to select either a five or ten frame filter
for Path RDI detection.
Notes:
1. This code is only transmitted by Old Equipment. New Equipment can therefore identify that it is
2. This code is only generated by New Equipment.
