Today I'll try to sent you as soon as posible the PRI quotation from TT&T. Yesterday, I just discussed with CAT telecom about PRI line for comparison the cost.
They're checking the distance preparing the quotation. Becuase they provide main cable for Cs loxinfo which we used for service the customers. I plan to move this line to new factory.
I think, they can also provide PRI and SDSL line by optical fiber to the same cable. It should be better for installation cost.
