The CRTC is requesting comment on whether regulatory measures are required to prevent service interruptions after a dispute between two telecommunications providers in January. In a notice of consultation posted to its website Thursday, the regulator said that it is considering implementing advanced notices before a telecom provider cuts services to another, after 27,000 NetTalk.com Inc. telephone customers lost service when Iristel Inc. disconnected the former for failing to pay. Only incumbent local exchange carriers are currently subject to regulatory obligations, which include providing notices before they disconnect service, said the CRTC. However, they can “cease providing non-regulated telecommunications services” without any “regulatory obligation to give those other providers notice prior to disconnection.” The commission is looking for comment on whether a time frame for a disconnect notice is required, if providers should tell the commission when a notice is issued so it can try to resolve it, whether there are other measures it can take to prevent interruption, and to which telecom services these measures should apply. The deadline for interventions is Sept. 19.
