Item 2.04. Triggering Events That Accelerate or Increase Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement.

As previously announced on November 7, 2005, Terayon Communication Systems, Inc. has delayed the filing of its Quarterly Report on Form 10-Q for the period ended September 30, 2005 (“Form 10-Q”). As a result of this delay, Terayon is not in compliance with its obligation under Section 6.2 of the Indenture dated July 26, 2000 with respect to Terayon’s 5% Convertible Subordinated Notes due 2007 to file with the Securities and Exchange Commission and the Trustee of the Notes all reports, information and other documents required pursuant to Sections 13 or 15(d) of the Securities Exchange Act of 1934.

Under Section 8.1 of the Indenture, an Event of Default shall occur if Terayon fails to cure a default within 60 days after written notice to the Trustee or to Terayon and the Trustee by holders of at least 25% in aggregate principal amount of Notes outstanding. On January 12, 2006, Terayon received a letter from holders of more than 25% in aggregate principal amount of Notes outstanding providing written notice to Terayon that it is in default based on Terayon’s failure to file its Form 10-Q.

If an Event of Default were to occur, the Trustee by notice to Terayon, or the holders of at least 25% in aggregate principal amount of Notes outstanding by notice to Terayon and the Trustee, may accelerate the maturity of the Notes and declare the entire principal amount of the Notes, together with all accrued and unpaid interest thereon, to be due and payable immediately. The Notes currently outstanding have an aggregate principal amount of $65 million.

The foregoing description is qualified in its entirety by reference to the Registrant’s Press Release dated January 13, 2006, a copy of which is attached hereto as Exhibit 99.1 and incorporated herein by reference.
