SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES
The following events (indications) are defined
norm_point :
NDF_enable:
disabled NDF + ss + offset value equal to active offset
enabled NDF + ss + offset value in range for the configured
tributary type
AIS_ind:
inc_ind:
H1 = 'hFF, H2 = 'hFF
disabled NDF + ss + majority of I bits inverted + no majority
of D bits inverted + previous NDF_enable, inc_ind or dec_ind
more than 3 frames ago
dec_ind:
disabled NDF + ss + majority of D bits inverted + no majority
of I bits inverted + previous NDF_enable, inc_ind or dec_ind
more than 3 frames ago
inv_point:
new_point:
inc_req:
not any of above (i.e., not norm_point, and not NDF_enable,
and not AIS_ind, and not inc_ind and not dec_ind)
disabled_NDF + ss + offset value in range for the configured
tributary type but not equal to active offset
disabled NDF + ss + majority of I bits inverted + no majority
of D bits inverted
dec_req:
Notes:
disabled NDF + ss + majority of D bits inverted + no majority
of I bits inverted
1. Active offset is defined as the accepted current phase of the SPE (VC) in the
NORM_state and is undefined in the other states.
2. Enabled NDF is defined as the following bit patterns:
1001, 0001, 1101, 1011, 1000.
3. Disabled NDF is defined as the following bit patterns:
0110, 1110, 0010, 0100, 0111.
