OTTAWA – The CRTC has issued a call for comments on a proposed model tariff for the 9-1-1 emergency response service offered by competitive local exchange carriers (CLECs).The Commission developed a proposed 9-1-1 emergency response service model tariff for CLECs based in part on a proposal submitted by MTS Allstream in September. MTS asked to amalgamate its six existing provincial 9-1-1 emergency response service tariffs into a single tariff that would apply in all areas where it operates as a CLEC. Rogers Cable filed a similar proposal the following month.Comments are due by February 9. www.crtc.gc.ca
