INTERNATIONAL BUREAU RELEASES 2007 YEAR-END CIRCUIT STATUS 
REPORT FOR U.S. FACILITIES-BASED INTERNATIONAL CARRIERS 
Data Reflects A Slow Growth of Total Capacity Used 
  
Washington, DC – The FCC’s International Bureau today released its annual year-end 
circuit status report for U.S.-international facilities-based common carriers.  The year-end 2007 
report shows that the use of U.S.-international facilities for international telephone calls, private 
line services and other services from the United States grew by 11 percent in 2007.   
 
The report relies on information provided by U.S.-international facilities-based common 
carriers and covers U.S. undersea cables, satellites and terrestrial links.  It identifies the activated 
(in-service) and idle (available, but not in-service) circuits for each international point as of 
December 31, 2007.  Additionally, for purposes of comparison, this report incorporates historical 
data from the 2004-2006 circuit status reports.  
 
Overall, the reported number of activated 64 Kbps equivalent circuits grew by 11 percent 
since 2006.  At year-end 2007, the reported number of activated 64 Kbps equivalent circuits 
totaled 8,403,971 as compared to 7,558,072 at year-end 2006.  
 
• By service type:  International Message Telephone Service (IMTS) accounted for 9.1 
percent of the total circuits used; International Private Line Services accounted for 
50.3 percent of total circuits; and approximately 40.6 percent of total circuits were 
used for services other than traditional private line services (including data services).   
 
• By transmission type:  Undersea cables accounted for 86.9 percent of the overall 
active transmission capacity; terrestrial links accounted for 12.9 percent; and satellite 
accounted for 0.2 percent. 
 
• The top 30 destinations among all international routes accounted for 97 percent of the 
total activated circuits.  The percentage of idle circuits (as compared to the total 
circuit capacity, active and idle) decreased from 49 percent in 2006 to 45 percent in 
2007. 
 
The report is available on the International Bureau home page at 
www.fcc.gov/ib/pd/pf/csmanual.html.  The report also is available for reference in the FCC 
Reference Information Center, Courtyard Level, 445 12th Street, SW, Washington, D.C.  Copies
