Devices

Three devices, one managed service

We deploy the model that fits the site, not the one that fits a catalog. Here is how the three compare.

The short answer

LineBridge deploys three managed POTS devices: a two-line cellular unit at $40 per month, an eight-line unit on your wired circuit at $70 per month, and an eight-line 5G/LTE outdoor-rated unit at $90 per month. Every price is all-in – device, connectivity, monitoring, and replacement – plus a one-time $149 install per site.

LineBridge C2

Two lines, cellular first

$40 / mo

A single elevator phone, a fire panel, or a fax line at a small site.

Up to 2 analog lines

LineBridge S8

Eight lines on your network

$70 / mo

Buildings with several analog lines and a reliable wired circuit already in place.

Up to 8 analog lines

LineBridge R8

Eight lines, 5G/LTE and outdoor rated

$90 / mo

Sites with no usable circuit, weak in-building signal, or outdoor mounting needs.

Up to 8 analog lines

Feature by feature

Detailed engineering specifications are shared under NDA during design. This is what matters when choosing a model.

Choosing

How we pick the model for a site

The choice comes down to line count, whether a usable circuit exists, and where the device has to live.

Line count

One or two lines – usually an elevator phone or a fire panel – go on the compact model. Three or more consolidate onto an eight-line device.

Transport

If a dependable wired circuit reaches the equipment room, we use it. If it does not, or coverage testing favors cellular, the 5G/LTE model becomes primary.

Environment

Parking structures, rooftops, gate houses, and unconditioned spaces get the weatherproof outdoor-rated model. Conditioned equipment rooms do not need it.
