Typo? mulcarriersuirers

The PROMCODE Interface Specification contains this sentence:
 
"Especially  when  used  for  providing management data for 
mulcarriersuirers, the same tool can be used without customizaton because 
no specific data conversion is required."

mulcarriersuirers is not a word. What is it supposed to be?

Regards,
