Field
Description
PHS Classifier
Refer
The reference ID for the classifier using this PHS rule.
PHS Classifier ID
The ID for the classifier using this PHS rule.
PHS Service Flow
Reference
The reference ID for the service flow using this PHS rule.
PHS Service Flow
ID
The ID for the service flow using this PHS rule.
PHS Dynsrv
Change Action
The action taken in a dynamic service change request for this PHS rule:
•
0 = Add the PHS rule.
•
1 = Set the PHS rule.
•
2 = Delete the PHS rule.
•
3 = Delete all PHS rules.
PHS Fields
The bytes of the headers that must be suppressed and restored during PHS
operation. For the upstream, this includes the PDU bytes starting with the first
byte after the MAC header checksum. For the downstream, this includes the PDU
bytes starting with the 13th byte after the MAC header checksum.
PHS Index
The index that references the suppressed byte string in the PHS Fields. The index
is unique per service flow in the upstream direction and unique per the cable
modem in the downstream direction.
PHS Mask
The mask used to interpret the bytes in the PHS Fields, where each bit indicates
whether the corresponding byte in the PHS Fields should be suppressed (0 = do
not suppress, 1 = suppress).
PHS Classifier Size The total number of bytes in the header to be suppressed.
PHS Classifier
Verification
Indicates whether the header bytes are to be verified before suppression (0 =
verify, 1 = do not verify).
