Network

Network Design

The Maine Enhanced 9-1-1 network design uses two existing Lucent No. 5ESS switching machines as Enhanced 9-1-1 control tandems. Both switches are engineered and equipped as fully redundant control tandems in the event of a failure of one of the switches.

FairPoint, Maine's service provider, builds dedicated SS7 trunks from each FairPoint host switch serving Maine residents to each Control Tandem. They are traffic engineered, on a P.01 basis, with a minimum of two trunks per end office to each control tandem.

Carrier Interface

FairPoint interfaces with each CLEC and LEC at their Point of Connection to provide a minimum of two redundant trunks using CCS/SS7 where available to the each of the two Control Tandems. Diverse routes are to be used when possible.

CLECs with Access Service Requests should contact their FairPoint account representative. Carriers should also notify the Bureau of their intent.

Reporting Network Outages

Incumbent LECs and facilities-based CLECs operating in Maine are requested to comply with the following procedures in notifying the Bureau and the Enhanced 9-1-1 Service Response Center (SRC) of planned and unplanned outages impacting a telephone customer's ability to access Enhanced 9-1-1.
