DOCSIS 4.0 FDD Diplexer Configuration

Retrieves The Currently Configured Diplexer Band-Edge Frequencies On A DOCSIS 4.0 Cable Modem.

Endpoint

POST /docs/fdd/system/diplexer/configuration

Request

Use the SNMP-only format: Common → Request TFTP parameters are not required.

Response

This endpoint returns the standard envelope described in Common → Response (mac_address, status, message, data).

data is an object with the SNMP index and an entry containing the configured band-edge frequencies (MHz).

Abbreviated Example

{
  "mac_address": "aa:bb:cc:dd:ee:ff",
  "status": 0,
  "message": null,
  "data": {
    "index": 0,
    "entry": {
      "docsFddCmFddSystemCfgStateDiplexerDsLowerBandEdgeCfg": 258,
      "docsFddCmFddSystemCfgStateDiplexerDsUpperBandEdgeCfg": 1794,
      "docsFddCmFddSystemCfgStateDiplexerUsUpperBandEdgeCfg": 204
    }
  }
}

Response Fields

Field Type Units Description
mac_address string — MAC address of the queried device.
status int — Operation status (0 = success; non-zero = failure).
message string — Optional result message.
data.index int — SNMP table index for the configuration row.
data.entry.docsFddCmFddSystemCfgStateDiplexerDsLowerBandEdgeCfg Unsigned32 MHz Downstream lower band edge (TLV 5.79).
data.entry.docsFddCmFddSystemCfgStateDiplexerDsUpperBandEdgeCfg Unsigned32 MHz Downstream upper band edge (TLV 5.80).
data.entry.docsFddCmFddSystemCfgStateDiplexerUsUpperBandEdgeCfg Unsigned32 MHz Upstream upper band edge (TLV 5.81).

Notes

  • A value of 0 for any band edge indicates the CM is not configured for extended-spectrum operation.
  • These settings reflect the CM’s active operating split and are read-only (advertised during registration).
