The Sector Ipai Relay Log
Starfleet Commnet One was a Starfleet communications network channel in use in the 24th century.
In 2369, this channel was mentioned in the Sector Ipai Relay Log, where it was noted that both Starbase 12 and the USS K'Marco had sent messages over this channel. The former had an encoded beta message, while the latter had a gamma one-three message. (TNG: "Aquiel")
