ADSG Broadcast Tunnel Setup
The eCM establishes the Cisco out-of-band (OOB) tunnels, the SCTE-65 SI tunnel,
and SCTE-18 EAS tunnel. You can use CLI diag page 4.3 to verify the setup of these
ADSG broadcast tunnels, as shown in the following example.
and SCTE-18 EAS tunnel. You can use CLI diag page 4.3 to verify the setup of these
ADSG broadcast tunnels, as shown in the following example.
Other tunnels may be specified in the DCD, but these are not processed.
Troubleshooting
If either the SCTE-65 SI tunnel or the SCTE-18 EAS tunnel is not present, verify with
the CMTS administrator that the DCD is correct.
the CMTS administrator that the DCD is correct.
Upstream Ranging
After the OOB tunnels are set up, the eCM initiates registration with the CMTS and
performs reverse path ranging to establish the correct transmit power level.
performs reverse path ranging to establish the correct transmit power level.
The upstream power level reported in CLI is 13.7 dB higher than the level at Port 1
because it is measured internally before attenuation. For example, a CLI reported
power level of 49 dBmV would imply a power level of (49 - 13.7 =) 35.3 dBmV
measurable at Port 1.
