Description
X.
PID Compression enabled.
Address/Control Compression enable.
Multi-link Group. This must be set to the Multi-link
bundle number. Does not apply if in Single Link Mode.
1 indicates that this channel is Multi-link.
Indicates data type as follows:
000 – PPP
001 – FR (UNI/NNI format)
010 – Transparent Mode
011 – FR (End-to-End format)
1XX – Unused
The HDLC Channel for Single Link Mode. Does not
apply if in Multi-link Mode.
X
TPA reporting mode. If 0, TPA reports whether or not
an entire MTU can be accepted. If 1, TPA reports
whether EQM FIFO size is below or above the space
threshold (SPC_THR or ML_SPC_THR).
Reserved. Must be left at default or set to 00 for correct
operation.
1 – Enable detection of EOP Loss. If the Any-PHY
channel number changes before end-of-packet is
received, the next segment will be interpreted as end-
of-packet.
Reserved. Must be left at default or set to 0 for correct
operation.
X. Read only.
X
MTU size in chunks for high-priority traffic. Defaults to
0. Only used when TPA_MODE is set to 0. Must be
left at default or set to 0 if TPA_MODE is set to 1.
X
MTU size in chunks for low-priority traffic. Defaults to
0x12C (i.e. 300 decimal, corresponding to 9600 bytes).
Only used when TPA_MODE is set to 0. Must be set to
0 if TPA_MODE is set to 1.
