Description: A list of Service Class Names (SCN) tags associated to
PHBID/Flow IDs.
The policies associated to each DEPI Flow ID of this table
allow the mapping of specific DOCSIS Service Flows well
distinguished by SCN.

The SCN encoding does not include the null terminated 
octets as DOCSIS specify for other configuration mechanisms
such as Cable Modem config files encoding.

This object is applicable to M-CMTS core but not to 
EQAM devices.

In D-MPT mode no tags are needed since all DOCSIS traffic
is mapped to same DEPI Flow ID, thus this object is set to
zero-length string (no tag) or ignored.

In PSP mode DOCSIS MAPS, DOCSIS MAC messages  and PacketCable 
1.0/1.5 voice traffic are mapped to the highest priority DEPI 
Flow ID (lower sequence number in the Resource allocation
response)

If this object is empty (no tag), the default policy is 
used. 

In PSP mode the default policy consists to assign the DEPI 
Flow ID of the lowest priority (highest sequence number) to
the DOCSIS traffic. DOCSIS Traffic not matched to a policy 
Tag is mapped to the default policy Flow ID.

In PSP mode the docsIfMCmtsDepiRsrcAllocSeq values pointed 
in a M-CMTS Core Resource Allocation Request has the 
preconfigured Policy Tags to map DOCSIS traffic to DEPI 
Flow IDs. When the Resource Allocation response from the 
EQAM is received, it could have same or less of the PHBIDs
requested, and the PHBID references could be in a different
order sequence. Therefore, the M-CMTS Core MUST accommodate
the policy Tags initial configuration to the EQAM order 
sequence and number of PHBIDs.

For example:
A Resource Allocation Request: 
Seq Num   PHBID   Flow ID   UDP Port   Policy Tags
--------  ------  --------  ---------  ------------
1         EF                           VoiceGold*  
2         AF                           VideoConference
3         BE                           empty  - no tag -

* - PCMM voice service based on SCN, no PacketCable 1.0/1.5
    voice

The EQAM Resource Allocation response:

Seq Num   PHBID   Flow ID   UDP Port   Policy Tags
--------  ------  --------  ---------  ------------
1         EF      6         50201 
2         BE      7         50202

It is vendor specific to re-allocate the policy Tags in the
case of less DEPI Flow IDs in the Resource Allocation 
response than in the requests. In the example PHBID AF 
policy tag could be assigned to either Flow ID 6 or 7

Final Resource Allocation Tag reordering

Seq Num   PHBID   Flow ID   UDP Port   Policy Tags
--------  ------  --------  ---------  ------------
1         EF      6         50201      VoiceGold 
                                       VideoConference
2         BE      7         50202      empty  - no tag -

Change of sequence in the response example:

A Resource Allocation Request: 
Seq Num   PHBID   Flow ID   UDP Port   Policy Tags
--------  ------  --------  ---------  ------------
1         0x30                         VoiceGold
2         0x20                         VideoConference
3         0x10                         empty  - no tag -

* - PCMM voice service based on SCN, no PacketCable 1.0/1.5 voice

The EQAM Resource Allocation response:

Seq Num   PHBID   Flow ID   UDP Port   Policy Tags
--------  ------  --------  ---------  ------------
1         0x20    6         50201 
2         0x10    7         50202
3         0x30    8         50203

Final Resource Allocation Tag reordering

Seq Num   PHBID   Flow ID   UDP Port   Policy Tags

1         0x20    6         50201      VoiceGold
2         0x10    7         50202      VideoConference
3         0x30    8         50203      empty - no tag -
