Formal Escalation – Plant Infrastructure Failure / Service Not Delivering Advertised DOCSIS 3.1 Capability
I am requesting formal escalation to Comcast Network Engineering and Regional Plant Maintenance. A Comcast technician confirmed that my neighborhood is operating on a 1996 Proteous HFC plant, which is not capable of supporting DOCSIS 3.1 service as advertised.
My modem diagnostics show:
DOCSIS 3.1 OFDM MER = 0.0 dB
OFDM correctables > 100 million
DOCSIS 3.0 QAM channels showing severe FEC overload
Upstream OFDMA disabled due to plant noise
Downstream power/SNR normal, eliminating premise wiring as a cause
These readings demonstrate that the plant cannot deliver the DOCSIS 3.1 service tier being billed. This constitutes a failure of service delivery under standard broadband service obligations and local franchise authority requirements for infrastructure maintenance.
This is a node‑level infrastructure failure, not a customer‑side issue.
I am requesting:
Escalation to Network Engineering
Dispatch of a Maintenance Technician
Full node sweep and plant impairment analysis
Evaluation for node rebuild or modernization
Written confirmation that engineering has reviewed the OFDM failure
A ticket number tied to Network Maintenance / Plant Engineering
Please do not send another premise technician. This requires engineering intervention.
Thank you.
