DEPI Feature Highlights 
Data plane extension during PRE - SSO 
DEPI control and session will be renegotiated on the secondary PRE after SO. The 
Dataplane on the RFGW1 should continue to forward data traffic, SYNC’s, 
MAP/UCD for up for 60 seconds although the control plane is down, to allow traffic 
to flow during the PRE SO. . Note the sessions as observed on the Monitor->session 
page would be moved to Del-Wait state. Once the new DEPI control and session are 
established, the Data plane can be reprogrammed. 
The idea is to make sure the modems stay online and there is no disruption in the 
traffic during a PRE SO. 
DEPI Path Redundancy 
DEPI Path Redundancy is a method for creation and management of redundant 
DEPI connections between the M-CMTS Core and the EQAM. The high availability 
requirements demands that the CMTS’s architecture must avoid single points of 
failure through support for redundant sub-components involved in DEPI and the 
ability to operate with redundant DEPI connections. 
DPR introduces two types of DEPI data sessions: primary sessions and secondary 
sessions. DPR provides redundancy at the data session level. Primary sessions are 
used to transport encapsulated DOCSIS data under normal conditions. Primary 
sessions are equivalent to generic DEPI sessions, when DPR is not supported. A 
secondary session serves as always-ready substitute for a primary session associated 
with the same QAM channel. A secondary session can be utilized to carry DEPI data 
when the associated primary session becomes unavailable as result of a failure or an 
operator action 
Note: The Monitor->Depi details -> Statistics page indicates the session type that is 
currently active on a specific QAM channel.

Introduction 
This feature allows the operator to configure the RFGW-1-D such that 
it can insert SI data from the headend for the locally inserted channels 
which are carried in unreferenced PIDs and remap it to standard SI 
PIDs in the RFGW-1. The user can perform the following tasks: 
 Remap unreferenced PIDs from a data stream or MPTS stream. 
 Block specific unreferenced PIDs from a data stream or MPTS 
stream. 
 Block all the unreferenced PIDs from a data stream or MPTS 
stream. 
 PID remapping is implemented on a QAM channel level. 
 PMT PIDs from SPTS and MPTS streams on the QAM channels 
configured in “Video” mode. 
 Blocking PMT PIDs in the SPTS and MPTS stream. 
 Inserting PAT from the external data stream.

Enabling the Feature 
1 Login to the RFGW-1 and go to the System/System Configuration page. 
2 Scroll down and set the Unreferenced PID Mapping feature to Enabled. 
3 Click Apply.

Adding Entries to the Remap Table 
1 In the Unreferenced PID Maps tree, select the QAM channel which requires PID 
mapping. 
2 Click Add row in the Unreferenced PID Map Table and enter the value of Input 
PID and required Output PID. You can add multiple rows. The maximum 
number of remapping rows supported is 32 per QAM channel 
3 If there is a need to block a specific PID in the stream, the  operator can specify -1 
at the Output PID Number column, effectively blocking the PID specified in the 
Input PID Number column. 
4 Click Apply. 
5 Click Save. 
6 The color coding descriptions are shown below. 
a Yellow – The existing row values were changed  
b Green – New row is being added 
c Red – The row will be deleted when you click Apply. 
  
  
						

							 
 
 Blocked Unreferenced PIDS 
 
78-4025112-01 Rev H0 143 
 
Blocked Unreferenced PIDS 
Unreferenced PIDs in MPTS and Data streams can be blocked by checking the 
corresponding boxes of the QAM channels in the Block Unreferenced PID table. 
By enabling the checkboxes in the PID table below, the following effects on the 
MPTS and Data streams configured on the QAM channel will occur. 
1 Block all the unreferenced PIDs of the MPTS and Data streams on a QAM 
channel. This will include any standard SI PIDs coming along with the MPTS 
streams. 
2 Will not block the PIDs mentioned in the PID remap table in any of the QAM 
channels. 
3 If the operator needs to pass-through a specific Unreferenced PID after enabling 
this Block Unreferenced PID, an entry can be added in the remap table with the 
output PID values the same as the input PID value.

Enabling Insert External PAT 
Use the table below to enable/disable insertion of external PAT at the QAM channel 
level. This table is located on the Feature Page.  
 
Below are the implicit effects of enabling insertion of external PAT on a channel. 
1 All types of streams configured on this channel will be passed through. 
2 PAT generated internally by RFGW will not be inserted in the QAM channel 
3 Operator can insert PAT from an external data stream in the channel. 
Operator can block/remap PMT PIDs on the channel to the value in (external) PAT 
manually by using the Unreferenced PID Map table. 
 
 
  
						

							 
 
 Operator Responsibilities 
 
78-4025112-01 Rev H0 145 
 
Operator Responsibilities 
PID Remapping 
1 When specifying the PAT PID to be remapped, the operator should ensure that 
the PID comes only on one stream on that channel.  
2 When remapping unreferenced PID / PMT PIDs, the operator should make sure 
that the desired output value of the remapping is not an existing ES or PMT PID 
of a stream on that channel. This will log output PID conflict in the System-
>Logs page. 
3 When using the Block unreferenced PID option, the unreferenced PIDs of the 
MPTS stream and data stream will be blocked. This might include NIT, SDT, 
BAT, etc., on an MPTS stream so use this with caution. In case there is a pressing 
need to use this option and the NIT, SDT, BAT needs to be inserted at the output, 
specify this in the PID remap table with the same input and output PID values. 
4 When remapping the PMT from the data stream, the operator should make sure 
that the output PID value is not the same as any existing PMT on the channel.   
Inserting External PAT 
1 Operator should take care of input PID conflicts i.e. ES and PMT PIDs of each 
stream should be unique within a given QAM channel. This is applicable for 
SPTS and MPTS stream with the Insert external PAT enabled as the streams are 
passed through when this option is enabled. 
2 Operator should ensure that the unreferenced PID remapped should appear on 
only one stream on a QAM channel at any given point of time. If the same PID 
appears on two different channels, there will be CC errors at the output. 
3 The Insert External PAT is supported only on the channels in the table based 
video mode.  
4 When specifying the PAT PID to be remapped, the operator should ensure that  
that the PID appears only on one stream on that channel.  
5 When remapping an unreferenced PID/PMT PID, the operator should make 
sure that the desired output value of the remapping is not an existing ES or PMT 
PID of a stream on that channel. This will cause an output PID conflict in the 
System->Logs in the RFGW. 
6 When remapping PMT from the data stream, the operator should make sure that 
the output PID value is not the same as any existing PMT on the channel.
