Description: This attribute specifies the current configured value for the Downstream upper band edge of the diplexer in the CM device. This corresponds to the Diplexer Downstream Upper Band Edge Configuration reported by the CM in its REG-REQ.

What is docsIf31CmSystemCfgStateDiplexerCfgDsUpperBandEdge?

Reports the currently configured downstream upper band edge frequency for this modem's diplexer, as reported by the modem itself in its REG-REQ registration message. Admins compare this active value against the modem's hardware capability ceiling in docsIf31CmSystemCfgStateDiplexerDsUpperCapability to see whether the modem is configured to use its full downstream spectrum range.
