Trinity dispatches on the 155.16000 DCS 125 for the Lowell area 911 Operations. The Haverhill division was on an LTR system out that way that they licensed from a private provider, so that was always subject to change. For the most part, the Haverhill area the 911 trucks are dispatched by their respective Fire Departments and Rock County Fire in NH, so their company channels would not have much traffic in comparison to the Lowell channel.
