Exhibit 99.1

TII NETWORK TECHNOLOGIES REPORTS 2007 YEAR END RESULTS

FOURTH QUARTER SALES INCREASE 50%

EDGEWOOD, NY – March 31, 2007 – TII Network Technologies, Inc. (Nasdaq: TIII), a company that develops and manufactures connectivity and data distribution solutions for the communications industry, today announced its results of operations for the three and twelve months ended December 31, 2007.

Net sales for the three months ended December 31, 2007 were $12.0 million compared to $8.0 million for the comparable prior year period, an increase of $4.0 million or 50.3%. The growth reflects increased sales of connectivity products, home networking products and digital subscriber line (DSL) products.

Non-GAAP operating income, which excludes restructuring charges of $46,000 related to the closing of our facility in Puerto Rico in 2007, was $734,000 for the three months ended December 31, 2007 compared to a loss of $37,000 for the comparable prior year period, an improvement of $771,000. Operating income for the three months ended December 31, 2007 was $688,000 compared to a loss of $37,000 for the comparable prior year period, an improvement of $725,000.

Income before taxes in the fourth quarter 2007 was $755,000 compared to $16,000 in the comparable 2006 period.

Net income for the fourth quarter 2007 period was $6.1 million or $0.44 per diluted share, including a tax benefit of $5.3 million or $0.39 per diluted share. For the fourth quarter 2006 period, net income was $1.5 million or $0.11 per diluted share, including a tax benefit of $1.5 million or $0.11 per diluted share. The tax benefit resulted from a reduction of our deferred tax asset valuation allowance and is net of Federal and state taxes on pre-tax income at statutory rates.

Net sales for the year ended December 31, 2007 were $46.8 million compared to $39.1 million for the similar prior year period, an increase of $7.7 million or 19.8%. The growth reflects increased sales of home networking products and connectivity and DSL products, partially offset by decreases in sales of our network interface products.

Non-GAAP operating income, which excludes restructuring charges of $1.1 million related to the closing of our facility in Puerto Rico in 2007, was $2.6 million for the year ended December 31, 2007 compared to $1.8 million for the comparable prior year period, an increase of $824,000 or 47%. Operating income for the year ended December 31, 2007 was $1.5 million compared to $1.8 million for the comparable prior year period, a decrease of $300,000 or 14.4%.

Income before taxes in 2007 was $1.7 million compared to $2.0 million in the comparable 2006 period.

Net income for the year ended December 31, 2007 was $6.4 million, or $0.47 per diluted share, including a tax benefit of $4.8 million or $0.35 per diluted share. Net income in 2006 was $2.7 million, or $0.20 per diluted share, including a tax benefit of $710,000 or $0.05 per diluted share. The tax benefit resulted from a reduction of our deferred tax asset valuation allowance and is net of Federal and state taxes on pre-tax income at statutory rates.

A reconciliation of non-GAAP operating income to our GAAP operating income (the most directly comparable GAAP measure) is set forth at the end of this press release.

Kenneth A. Paladino, President and Chief Executive Officer, stated, “The continuation of our sales growth reflects increases across most of our product lines and resulted in a 47% increase in operating income for the year, excluding the restructuring charges. The restructuring charges resulted from the closure of our Puerto Rico facility in September 2007 and the consolidation of the operations previously conducted in that facility into our new, owned facility in Edgewood, New York, which we moved into in June 2007. With the consolidation of operations completed, which improves our operating efficiencies, and anticipated further growth in sales of our new products under our product and customer diversification strategy, we believe our profitability will continue to increase. These improved financial results validate that we are successfully executing our product and customer diversification strategy, a strategy that we believe will result in continued success into 2008.”
