The CRTC denied a request Friday by MTS Allstream Inc. to direct Telus Corp. to stop applying a per-order charge related to dry loops. Dry loops are telephone lines with no dial tone. In September MTS told the commission Telus was charging the company for each dry loop it ordered, along with a per-order service charge. But MTS said it should only have to pay for the service charge, and asked to be refunded the additional charges. But Telus said the charge is an authorized part of the tariff. The commission agreed in its decision, denying MTS' request. MTS also asked to be refunded charges that Telus applied to signal transfer points—where routers relay data—in Edmonton and Calgary. Telus agreed that MTS should not have been charged but the parties disagreed on the amount of the refund. The commission said in its decision that MTS gave Telus sufficient notice about the disputed charge in a February 2007 email, and directed Telus to refund from that point on.
