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.

All three models present real analog dial tone, are supervised 24/7 per line, and ship preconfigured and labeled for the equipment they serve.
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.
