***   Testing of Telephony Voice Channels  ***
***   for proper operation with MODEMS     ***

Dear Tereggers,

I am looking  for specifications or definitions to assist me in 
evaluating telephone channels operating with MODEMs at rates of 28.8Kb/s 
and 33.6Kb/s.

The Telephony equipment is defined and tested according to CCITT G715 
requirements, however, from my experience - conformance to G715 does not 
necessarily assure proper operation with all types of  MODEMs.

I would highly appreciate receiving any sort of definition, 
specification or comments one might have on the subject.

I am specifically interested in requirements and specs. to evaluate and 
test performance  of the equipment  in production. 

Regards,
Amos Maor
