Configuring Cable Fiber Nodes for the XD CAM
The mapping of ports to F-connectors is different for Annex A and for Annex B. Choose the correct set of commands below.
Annex A
# Configure cable fiber-nodes as appropriate (based on 32D CAM downstream port-to-connector mapping
for Annex A)
configure cable fiber-node "1" cable-downstream 14/0 14/1 14/2 14/3 14/4 14/5 14/6 14/7
configure cable fiber-node "2" cable-downstream 14/8 14/9 14/10 14/11 14/24 14/25 14/26 14/27
configure cable fiber-node "3" cable-downstream 14/12 14/13 14/14 14/15 14/16 14/17 14/18 14/19
configure cable fiber-node "4" cable-downstream 14/20 14/21 14/22 14/23 14/28 14/29 14/30 14/31
Annex B
# Configure cable fiber-nodes as appropriate (based on 32D CAM downstream port-to-connector mapping
for Annex B)
configure cable fiber-node "1" cable-downstream 14/0 14/1 14/2 14/3 14/4 14/5 14/6 14/7
configure cable fiber-node "2" cable-downstream 14/8 14/9 14/10 14/11 14/12 14/13 14/14 14/15
configure cable fiber-node "3" cable-downstream 14/16 14/17 14/18 14/19 14/20 14/21 14/22 14/23
configure cable fiber-node "4" cable-downstream 14/24 14/25 14/26 14/27 14/28 14/29 14/30 14/31
# Restore the 32D CAM slots
configure slot 14 no shutdown
configure slot 15 no shutdown
Annex A Mixed Modulation per F-connector
This feature is intended for certain operators who because of noise in the physical plant cannot always use 256-QAM and
who because of space or fiscal concerns are reluctant to add more XD CAMs or CMTSs in their headends. This feature gives
such customers greater flexibility.
Restrictions and Clarifications
MSOs and operators should be aware of the following aspects of this feature:
This feature applies only to the XD-CAM.
