Table 28: Existing DOCSIS Service Characterization

Table 29 on page 78 and Table 30 on page 80 are provided to collect upstream and
downstream characterization information for a DOCSIS Module. If the CMTS configuration
includes more than one DOCSIS Module, additional tables are provided in "Additional
Characterization Tables" on page 85.
