so what about the telephones for the people still there?
OK, it is noted that (403) 777 telephone exchange was shut down. I guess the phones that were still on it would have had to be merged into some other nearby exchange, but which one?
Places in NWT (Northwest Territories) would have later gone into area code 867. My undestanding is that 403-777 was then taken for use at Calgary. 867-777 came into use at Inuvik (had been 403-979, but 867-979 was taken by Iqaluit, whose 979 prefix came into area 867 from area 819, not from area 403. — Preceding unsigned comment added by 184.108.40.206 (talk) 16:14, 15 February 2013 (UTC)
There was no merge to another exchange. The nearest by road was Watson Lake, and it made no sense to transfer service there. There was virtually no telephone traffic in and out of Tungsten, so the service was simply turned down. Any caretakers at the mine would use the VHF radio telephone base station in the area, and by then, satellite telephony was emerging (Iridium or such). Had the mine reopened with a community of resident miners, the exchange might have been revived, and only replaced with a digital switch if one was surplus to the company's needs after being replaced with a larger unit in another community. As of 1995, digital replacement would have been essential to be compatible with the NANP switch to interchangeable NPA codes. (I worked for Northwestel from 1981-2007, so I was aware of happenings with Tungsten.) GBC (talk) 07:21, 1 January 2014 (UTC)
