16 Juniper Networks G10 CMTS Pre-Installation Guide
If the installation site supports more than two DOCSIS services, the characterization of the
additional services is to be captured in Table 10. In addition, if the desired CMTS
configuration includes more than one DOCSIS Module, the additional tables, beginning on
page 17, can be used as needed.

If yes, FEC level parameters (T and K)
Upstream measured C/N
Downstream RF bandwidth allocated
Downstream modulation type
Downstream output signal level (relative to analog video)
Downstream measured C/N
Downstream interleave depth setting
