First, you'll have to decide whether you need to know about 
     "PUBLIC" standards versus "PRIVATE" standards.
     
     1.   PUBLIC standards are by ENFORCED by law.  Within the United
          States these are not necessarily limited to the following:
     
          UL style tests for product safety:
     
               UL-1459 for telephone equipment,
               UL-1950 3rd edition effective year 2000 for Information
                     Technology Equipment (ITE) and Telecomm equipment.
     
               This type of product approval is enforced by OSHA and
               written into the National Electrical Code.
     
          FCC style tests for electromagnetic emissions:
     
               Part 68 for telephone equipment,
               Part 15 Class A for alot of other equipment.
     
               This type of product approval is enforced by the FCC.
     
     Product Safety testing can be performed only by labs certified as an 
     NRTL (Nationally Recognized Testing Laboratories).  An NRTL is 
     approved to be an NRTL by OSHA.  Not to give you any bias, the 
     following NRTLs are in alphabetical order:   ELT, MET, UL.
     There are many others.
     
     Emissions testing for the United States can be performed only at labs 
     registered with the FCC.  A cross check of those labs is done by an 
     agency called NVLAP.
     
     2.   PRIVATE standards are those standards not enforced by law but by  
          the customer through contractual agreement.  Within the United    
          States for Telco equipment this includes BELLCORE.
     
          BELLCORE has more than enough standards for anyone.  The complete
          set of BELLCORE standards costs over $20,000.00  To make a claim
          that a piece of equipment is completely BELLCORE compliant would
          in my estimation be an unrealistic claim.
     
          The following BELLCORE standards would be a good start:
     
          GR-63, TR-78, TR-499, TR-1089.
     
     To get more information contact any lab that advertises UL product 
     safety testing, FCC emissions testing, and Bellcore itself.

Please send me any information on the certification process and industry 
standards which now affect the cable and/or telephony industry.  I'm 
conducting research for my company.
     
Thank you very much,
