Alternative Analog sources

[macdouglas]

I have a building that the owner renovated and pulled out all inside plant and removed the d-mark and MPOE.

I need to get 2 analog lines for fax and TTY into the space.

The owner rejected the closest run from the pedestal to the building because he wants to add-on there, and that forces us to place the MPOE at the far corner of the building and hang 475' of conduit through the space. Several thousand to install 4 analog lines is ridiculous.

It's possible the internet provider might be able to provide dial tone from an ONT or ATA, but what are some other options? Cellular to analog?

Hi macdouglas,
Have a look at callcentric.com. They can provide VoIP phone numbers. You run a network cable to whatever location you want, and then put down either a device that will convert IP to dial-tone, or you can get a phone that is configurable. The advantage of the first option is ANY analog phone will then plug to the device, and you can use it for standard phone service. The "digital phone" option has it's own advantages, but depends on if you want a fixed old version nostalgia analog phone.
I'm currently using both a Grandstream VoIP box, which supports 2 separate lines, and I'm using a digital phone Grandstream GXP2130.
The Callcentric site has a list of compatible devices, and how to configure them for use on their system. A local phone number runs $1.95 a month.

That does sound like a tough situation, especially just for fax and TTY. If the internet provider can give you a solid ONT with POTS ports or a reliable ATA, that might be your cleanest workaround—especially if faxing is low volume.


Cellular-to-analog adapters like the ones from CellularGate or NetComm can work too, but you’d want to test signal stability, especially for TTY. Some services like Ooma or even VoIP with a UPS might also be worth a look, depending on compliance needs. Let me know more about the usage volume or provider constraints and I can suggest more specific options.

I’ve seen similar situations in retrofit projects. Sometimes a cellular to analog converter can be a temporary solution, especially if only 1-2 lines are needed for fax/TTY. Another option is an Ethernet extender over existing copper pairs if any are still in place—some units can deliver analog dial tone across distance.
