docs Mcast Dsid Phs Table

This object reports the set of DSID-Indexed PHS rules that are signaled between the CMTS and CMs as part of the Multicast Sessions setup. The attributes PhsMask, PhsSize and PhsVerify comes from the configuration object CmtsGrpPhsCfg. The value of the PhsField attribute is derived by the CMTS from the CmtsGrpCfg object parameters, and possibly other IP header informaton of the multicast session that the CMTS is capable of knowning prior to the multicast session setup. In cases where the PhsSize is longer than the CMTS knowledge of IP/TCP header fields, the CMTS extends the PhsMask with bits set to 0 until reaching the equivalent PhsSize value.
