                 CHARLES H. HOUSE ELECTED CHAIRMAN OF THE BOARD


COPIAGUE, NY -September 19, 2005 -TII Network Technologies, Inc. (Nasdaq: TIII),
a leading  provider of  telecommunications  network  protection  and  management
products,  today  announced  its results for the fiscal 2005 fourth  quarter and
twelve months ended June 24, 2005.

Net sales for the fourth  quarter of fiscal 2005 were $7.6  million  compared to
$6.2 million for the comparative  prior year, an increase of approximately  $1.3
million or 21.3%. The increase in sales over the prior year  comparative  period
was primarily due to an increase in installations of the Company's products upon
the conclusion of the extreme  winter  weather  conditions in the Northeast U.S.
that  hampered  these  installations  during  the  Company's  fiscal  2005 third
quarter.  Net sales for  fiscal  2005  decreased  $1.7  million or 5.9% to $26.8
million from $28.5 million in fiscal 2004. The decrease in sales for fiscal 2005
compared to fiscal  2004 was the result of a sharp  increase in the need for the
Company's  products in the first  quarter of fiscal 2004,  primarily  due to the
hurricanes that occurred during the summer of calendar 2003.

Gross profit for the fourth quarter of fiscal 2005 was $2.3 million  compared to
$1.8 million for the  comparative  prior  period,  an increase of  approximately
$482,000 or 26.5%,  while gross profit margin for those  quarters were 30.4% and
29.1%,  respectively.  Gross profit in fiscal 2005 was $7.9 million  compared to
$8.6  million in fiscal  2004, a decrease of  approximately  $713,000,  or 8.3%.
Gross profit  margins for those periods were 29.5% and 30.2%  respectively.  The
lower gross  profit  levels and margin were due to the effect of fixed  overhead
costs on lower sales levels.

Net  earnings for the fourth  quarter of fiscal 2005 were  $594,000 or $0.05 per
diluted share,  compared to $113,000 or $0.01 per diluted share, in the year ago
quarter.  Net  earnings  for fiscal 2005 were $1.4  million or $0.11 per diluted
share,  compared to net earnings of $1.6  million or $0.12 per diluted  share in
fiscal 2004.

Timothy J. Roach,  President and Chief Executive Officer,  stated: "I am pleased
to report that the solid  performance  we achieved in fiscal 2004 has  continued
into fiscal 2005, as we delivered  profitable results for our shareholders.  Our
success in fiscal  2005,  which is  continuing  into a strong  fiscal 2006 first
quarter,  includes  our  focus  on our core  markets  and the  execution  of our
strategic plan to further  strengthen our  technology  while  expanding into new
markets.  This plan has been designed to recognize and address the rapid changes
in  technology  in the  telecommunications  industry  and the needs of alternate
service providers.

Fame, 1984; IEEE Fellow, 1990; EE Times Historic  Contribution Award, 1997; IEEE
3rd Millennium  Achievement Award, 2000. He was named in the Computer Museum and
National  Academy of  Science  exhibit  and book in 1997 as one of 200  National
"Wizards  of  Computing"  for  America.  In  addition,  he has been named to the
Electronic  Design  Hall of Fame for his work on Logic  Analysis - judged one of
the 20th century's top 50 inventions in electronics.

Mr.  House  holds a  Bachelor  of Science  degree in  Solid-State  Physics  from
California  Institute of  Technology,  a Master of Science degree in Electronics
Engineering from Stanford University,  a Master of Arts degree in the History of
Science and Technology  from the University of Colorado and a Master of Business
Administration  degree in Strategic Studies from the University of California at

Mr. Roach  continued:  "We are very pleased that Mr. House has been  unanimously
selected by the Board as the Company's  next Chairman of our Board of Directors.
Since  joining our Board,  he has brought an  exceptional  blend of  technology,
marketing  and  business  acumen  to our  Company  as we  develop  and bring new
products to market.  We welcome his  understanding of the strategic and business
challenges  faced by TII and are grateful for his  continued  commitment  to our
Company."

Statements   in  this   release   that   are   not   strictly   historical   are
"forward-looking"  statements  and should be  considered as subject to the risks
and  uncertainties   that  exist  in  the  Company's   operations  and  business
environment.  These  factors  include,  but  are not  limited  to:  exposure  to
increases in the cost of the Company's products, including increases in the cost
of the Company's  petroleum-based plastic products; the Company's dependence for
products and product components on Pacific Rim contract manufacturers, including
on-time  delivery,  quality  and  exposure  to  changes  in cost in the event of
changes in the  valuation  of the Chinese  Yuan;  dependence  on, and ability to
retain,  its  "as-ordered"  general  supply  agreements  with its largest  three
customers  and  win  new  contracts;  continued  dependence  on the  traditional
copper-based  Telco market which has been  declining over the last several years
due principally to the impact of alternate  technologies  and  competition  from
multi-system  operators;  the ability of the Company to market and sell products
to new markets beyond its principal market - the copper-based  Telco market; the
Company's  ability to timely develop products and adapt its existing products to
address  technological  changes,  including changes in its principal market; the
potential  for the  disruption  of shipments as a result of, among other things,
third party labor disputes and political unrest in or shipping  disruptions from
countries in which the Company's  contract  manufacturers  produce the Company's
products;   weather  and  similar   conditions,   particularly   the  effect  of
hurricanes/typhoons  on the  Company's  manufacturing,  assembly  and  warehouse
facilities  in Puerto  Rico or the Pacific  Rim;  competition  in the  Company's
traditional  telecommunications market and new markets the Company is seeking to
penetrate;  potential changes in customers' spending and purchasing policies and
practices; general economic and business conditions,  especially as they pertain
to the  telecommunications  industry;  dependence  on third  parties for product
development;  risks  inherent  in new  product  development  and sales,  such as
start-up delays and uncertainty of customer acceptance; the Company's ability to
attract and retain technologically qualified personnel; the Company's ability to
fulfill  its  growth  strategies;  the level of  inventories  maintained  by the
Company's  customers;  the Company's  ability to maintain  listing of its Common
Stock  on  the  NASDAQ  SmallCap  market;   the  availability  of  financing  on
satisfactory  terms  and  other  factors  from  time  to time  discussed  in the
Company's SEC reports.
