TRENTON — Fox remains on the Optimum cable system as negotiations continue over how much parent company Altice will pay to carry Fox's local, cable, and broadcast channels.

As talks continued past a Monday deadline, the two companies have engaged in a war of words and websites defending their stances and the threat to pull Fox 5 and My 9 from Optimum, along with FX, Fox Sports 1, and the National Geographic channel. Fox News Channel is not affected by the contract.

Citing unnamed sources, Sports Business Daily reported both sides had agreed to a "short extension" to continue their negotiations. Optimum continued to carry all Fox channels as normal as of Tuesday morning.

On its website, Altice accused Fox of seeking "an exorbitant increase in programming fees, which affects your cable bill." Fox accused Altice of not entering into "substantive" negotiations until last week and is "now asking for preferential treatment that does not reflect the marketplace."

Neither company updated their sites about negotiations. A spokeswoman for Altice has not yet returned a message.
