CBS says there are currently no negotiations taking place with Time Warner Cable, which stopped carrying the network in New York and other markets on Friday in a spat over fees.
The network says in a statement that it had asked the cable provider to continue negotiating while its programming was still on the air. It says Time Warner rejected the request.
"We remain ready to negotiate in good faith when they are,'' CBS says in a statement.
A spokeswoman for Time Warner, Maureen Huff, had said earlier in the day that "Talks continue.''
The standoff means 3 million affected customers in New York, Los Angeles, Dallas and other cities do not have access to CBS.
The New York City Council is planning to hold an oversight hearing on August 8 demanding answers from both companies on the chain of events that led to the blackout.
