rdnCmtsDSModulation

Module: RDN-CMTS-MIB

OID (symbolic): RDN-CMTS-MIB::rdnCmtsDSModulation

OID (numeric): 1.3.6.1.4.1.4981.2.1.1.1.1

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-write

Description: The attribute to control the down stream modulation. When this object is set to FALSE(2), the downstream transmitter will output a CW, or tonal signal at the tuned RF frequency.

What is rdnCmtsDSModulation?

Read-write boolean controlling whether this downstream RF channel transmits modulated DOCSIS data; setting it to FALSE makes the transmitter output an unmodulated CW/tonal carrier at the tuned frequency instead. Technicians use the FALSE (CW) mode as a test signal for RF sweep/alignment work on the plant rather than for carrying subscriber traffic.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.4981.2.1.1.1.1
snmpwalk -v2c -c public <target> RDN-CMTS-MIB::rdnCmtsDSModulation

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.4981.2.1.1.1.1.1
snmpget -v2c -c public <target> RDN-CMTS-MIB::rdnCmtsDSModulation.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.4981.2.1.1.1.1.1 s <value>
