The Glen Rose ISD Board of Trustees voted unanimously Tuesday to replace and update fiber optics and phone system replacement.

The board had purchased a fiber optic network and a “voice over IP (“VoIP”) phone system, according to the agenda.

“Both systems have reached the end of their capacity for growth in the school district and need replacement,” the packet stated. “The lifetime, warranty, replacement of both the fiber and phones have reached a point where it is (no) longer cost effective to continue either as the primary technology for that category.”

The initial costs for the new fibert installation is listed as $230,000, and the costs for the phone system is $120,000 — making a total of $350,000 — to be provided through a budget amendment.

The motion for the budget amendment for the expense was approved by a 6-0 vote. Trustee Andy Snow, the board’s secretary, was absent.

Two members of the board — Vice President Tom Lounsberry and Kevin Taylor — were presented with retirement plaques.

Four candidates are running for those two expiring at-large places, and early voting began Monday.
