Hitron CODA-56

Overview

The Hitron CODA-56 is a DOCSIS 3.1 cable modem with a notably clean API design. DOCSight supports it via the hitron driver.

Property	Value
Driver Key	hitron
Auth Method	None (no authentication)
DOCSIS Version	3.1
Default IP	192.168.100.1
Channels	SC-QAM + OFDM (downstream), SC-QAM + OFDMA (upstream)

Setup

1. Set Modem Type to Hitron CODA-56 in DOCSight settings
2. No password needed - the modem has no authentication
3. Default modem IP: 192.168.100.1

Known Observations

Clean JSON API

The CODA-56 is one of the few modems that provides proper JSON endpoints for DOCSIS data, with dedicated endpoints for each channel type:

Endpoint	Channel Type
/data/dsinfo.asp	SC-QAM downstream
/data/usinfo.asp	SC-QAM upstream
/data/dsofdminfo.asp	OFDM downstream
/data/usofdminfo.asp	OFDMA upstream

Cache-Buster Required

All endpoints require a cache-busting query parameter (_={timestamp_ms}). Without it, the modem may return stale data.

Modulation as Integer Codes

Unlike most modems that report modulation as strings (e.g., "256QAM"), the CODA-56 uses integer codes:

Code	Modulation
0	16QAM
1	64QAM
2	256QAM
3	1024QAM
4	4096QAM

OFDM/OFDMA Lock Status

OFDM channels have a plclock field that must be "YES" for the channel to be active. OFDMA channels have a state field that must be "OPERATE".

Bridge Mode

Status: Untested, likely compatible. Usually reachable at 192.168.100.1.
