Wide Voice Raises 'Grave' Concerns About TDM Service Discontinuance

Wide Voice meeting with FCC Wireline Bureau staff raised "grave concern" about "imminent" time division multiplexed (TDM) voice service discontinuance. The company said Verizon discontinued live service-affecting TDM services after the meeting, per an ex parte filing Monday in docket 21-17 (see 2010200052). Wide Voice said no alternative options are available from any other provider and local end user calls from incumbent local exchange carriers (ILEC) to Wide Voice can be delivered. "All of the major ILECs have made it clear that these circuits are coming down ... with no substitute service in the foreseeable future," the company said. Wide Voice noted that "a solution exists right now to route this traffic to Wide Voice over existing arrangements" and it's "unreasonable" for a provider to "use outdated local/non-local traffic distinctions to allow this traffic to fail."
