Information About BFS QAM Support

The BFS provides a mechanism for a standardized downloading of applications, games, images, and other data formats required by the applications. The BFS QAM enables the router to transfer the broadcast data from an EC to the target platform such as a set-top unit. All forms of BFS data from EC flows as IP multicast, except the CVT carousel, which is through the GQI insert packets.

The BFS QAM configuration on the Cisco cBR-8 router varies based on the version of EC, which interfaces with the router.

  • For EC 7.x-Model a GQI-based LED as BFS QAM. One for each LC on Cisco cBR-8.

    For Remote PHY-A single GQI-based LED as BFS QAM for the entire Cisco cBR-8 chassis, as the Cisco cBR-8 can support DEPI multicast for all Remote PHY devices (RPD).

    For EC 8.x-EC 8.x multicasts CVT carousel data in addition to GQI insert packets, but only in the presence of GQAM configured as BFS QAM. Hence, in this setup, a single table-based LED, modeled as BFS QAM, for each Cisco cBR-8 chassis is sufficient. Using cross LC replication, this BFS data can be replicated to other LCs on the Cisco cBR.

How to Configure BFS QAM for EC 7.x

This configuration applies to Cisco cBR-8 routers running Converged Cable Access Platform (CCAP) with Ethernet input and RF output.

If Cisco cBR-8 interacts with EC 7.x, configure an LED on each line card. Use the following procedure to configure BFS QAM on Cisco cBR router.

  • Configure an LED with GQI protocol on each line card.

  • On EC 7.x, provision BFS QAM.

  • Manually create sessions on EC 7.x.

  • Generate the QAM, based on GQI model.

  • Generate a new source definition and use the new QAM as a target using the same PIDs.

  • Ensure that everything is set up on the EC to match the Cisco cBR-8 LED configuration.

This section contains the following:

Mapping Cisco cBR-8 as a GQI QAM

On the EC 7.x, configure BFS sessions on the registered BFS QAM by using one of the following:

  • Proprietary Remote Procedure Call (RPC) (with GQAM)

  • GQI (with RFGW-1)

You can use a standard GQI model where the sessions will be generated on the individual line card on a single LED per line card basis. Individual BFS sessions are added to the LEDs at the Source Definition for all in-band BFS sources. Sessions must be unique in numbering and QAM selection, although all other settings must be duplicates of the original settings.

Creating GQI QAM for BFS on EC 7.x

Prerequisites

  • To create the GQI QAM on the EC, enable packet insertion in the QAM Model.

  • You can duplicate the standard RFGW model to ensure that no interference occurs with the current operations.

  • The router must have a GQI QAM per LED.

  • The individual QAM must be BFS-capable.

Procedure

Use the following procedure to create GQI QAM for BFS.

  1. Choose EC > GQI Based QAM Model List > Edit GQI Based QAM.

  2. (Optional) Select the BFS Capable checkbox.

  3. Choose RF Carriers from the left pane.

  4. Ensure that the Carriers and Ethernet Port values are the same as those on the LEDs.

You can create the sessions for each BFS source by generating a Multicast Through GQI Based QAM session through each BFS source's Source Definition.

How to Configure BFS QAM for RPD

This configuration applies to Cisco cBR-8 routers running CCAP with Ethernet input and Ethernet output.

The configuration procedure for RPD is similar to the configuration on Cisco cBR-8 routers with EC 7.x. However, only one LED is needed for BFS QAM configuration.

You can use the sessions configured on the LED on every RPD by defining an Auxiliary Core on each RPD as needed for BFS distribution.

Creating SDG for BFS Sessions for RPD

The following example shows how to create SDG for BFS sessions on RPDs.

      virtual-edge-input-ip 203.0.113.1 input-port-number 1
      vcg vcg_bdcast

Defining Cable RPD

The RPD definition must include the RPD defined in the BFS SDG for every RPD to which you want to distribute BFS data: The following example shows how to define RPD. 

cable rpd RPD07

  core-interface Te2/1/4

How to Configure BFS QAM for EC 8.x

When Cisco cBR-8 interfaces with EC 8.x, all sessions on the router are configured as multicast and perform a multicast join.

The Cisco cBR routers are not directly mapped on the EC. Hence, this BFS QAM configuration requests and processes the multicast BFS sessions that are setup on the actual BFS QAM. If the Cisco cBR-8 routers have to process these sessions, you must set up table-based multicast sessions, which are similar to the ones available on the BFS QAM.

Configure QAM replication group (QRG), spanning across line cards (LC) to replicate these BFS sessions on every RF port (if each RF port is a service group) of every LC.

To replicate across line cards, you must configure table-based sessions. You can perform cross-line-card-replication only through table-based sessions.

Use the following procedure to configure BFS QAM on Cisco cBR router for EC 8.x.

  1. Create a VCG with one QAM channel for carrying this BFS data.

  2. Within the same VCG, allocate a few more QAM channels for MPTS pass-through sessions.

  3. Create VCG for VoD QAM channels.

  4. Create VCG for SDV QAM channels.

Creating VCG for VoD QAM Channels

The following example shows how to create VCG for VoD QAM channels.

virtual-carrier-group vcg_SDV

Creating SDG

The following procedures are applicable when you create an SDG.

  1. Create SDG for broadcast sessions and map this to as many RF ports as required, depending on the Service Groups which need this broadcast data.

  2. Create separate SDG for VoD.

  3. Create separate SDG for SDV, which probably contains replication.
