POTS IN A BOX® 90X2
The 90X1’s LTE sibling — same eight lines, same 48-hour battery, FirstNet Trusted, and the only model in the family approved on Bell Canada.
- 8 FXS lines
- LTE incl. band 14 (FirstNet)
- 48 hr battery
- AT&T FirstNet Trusted

What the unit actually does.
Six capabilities decide whether a line-replacement deployment works or generates tickets. Here is where the 90X2 stands on each.
- 01
Eight analog lines
Eight RJ-11 FXS ports with surge protection, identical in capacity and behaviour to the 90X1 — the difference between the two models is the radio, not the line count.
- 02
LTE including band 14
Bands 2, 4, 5, 12, 13, 14, 66 and 71 cover the mainstream North American carriers. Band 14 is FirstNet, and the unit is FirstNet Trusted.
- 03
Approved on Bell Canada
The only model in the family carrying a Bell approval, which makes it the default choice for Canadian sites and cross-border portfolios.
- 04
Up to 48 hours of standby
The same 18-cell 15Ah lithium-ion pack as the 90X1, with a higher 12VDC 4.0A UPS output for approved connected devices.
- 05
Line-grade analog behaviour
Ring-down, CPC, DTMF in and out of band and G.168 echo cancellation — the call-handling detail that determines whether legacy endpoints actually work.
- 06
Managed through Ara
Remote provisioning, firmware, line-state alerts, configuration changes without a reboot, and a documented API for OSS/BSS integration.
At a glance.
The POTS IN A BOX® platform terminates real analog lines on real FXS ports, then carries them over a managed cellular path with code-relevant battery backup. It is a purpose-built line-replacement platform, not a consumer cellular adapter with an RJ-11 jack on it.
Best fitSites without 5G, and anywhere FirstNet priority access matters.

The lines that come off copper.
These are the endpoints still hanging on a dial tone. Each one terminates on an FXS port and rides the managed cellular path instead.
- Elevator emergency phones
- Fire alarm panels
- Burglar and intrusion alarms
- Fax machines
- POS terminals and ATMs
- Emergency call boxes
- Gate entry and callbox systems
- M2M and SCADA links
- Telemetry and remote sensors
- Utility meter reading
It behaves like a line, because it is one.
Ring-down, CPC and echo cancellation are what make an elevator phone and a fire panel work on this path rather than merely connect to it.
- Ring-down (auto-dial)
- DTMF, in-band and out-of-band
- G.711 and G.729 codecs
- G.168 echo cancellation
- CPC (Calling Party Control)
- E911 with GNSS geo-location
- TTY / TRS support
- Caller ID and CWCID
- 3-way conference
- Hold, forward, transfer, waiting
The identifiers, in full.
Every number below is a real, verifiable listing. An AHJ will ask for them, so we publish them rather than describing the unit as "certified" and leaving you to find out.
| Standard | Identifier |
|---|---|
| UL 864 | Intertek reports 105634656CHI-001 and 105839662CHI-001 |
| UL 2054 | MH63085 |
| CSFM listing | 7305-2384:0002 |
| PTCRB | 126020 |
| FCC | XMR201909EC25AFXGrant holder: Quectel — modular grant for the embedded cellular module |
The 90X2 is aligned with UL 864 and NFPA 72 requirements for fire alarm signal transmission. NFPA 72 is a code that applies to the installed system, not a product certification. Note that the FCC identifier above is a modular grant held by Quectel for the embedded cellular module — unlike the 90X1, which carries DataRemote’s own grant. The 90X2 has no DOE or CEC appliance listing.
Carrier approvals
- AT&T FirstNet Trusted
- Verizon Open Development (2024-10-04)
- AT&T (ref 224456)
- T-Mobile IoT

Network layer
The device credentials above cover the equipment. The service obligations — E911 address association and dispatchable location, 911-call notification to designated contacts, and Kari’s Law and RAY BAUM’S Act support — are met on the MIX Networks voice network that carries the line. See how the three layers fit together.
Managed remotely, through Ara.
Every unit we deploy is enrolled in Ara, DataRemote's cloud management platform, and monitored by our NOC. Line-state changes raise an alert before the customer notices, and most faults are diagnosed without a site visit.

What buyers ask about the 90X2.
If the answer you need is not here, ask us directly — the line audit below is free and comes back within one business day.
- What is the difference between the 90X2 and the 90X1?
- The radio. The 90X2 runs on LTE bands 2, 4, 5, 12, 13, 14, 66 and 71; the 90X1 runs on 5G Sub-6. Both are eight-line units with the same 18-cell battery and the same Ara management. Choose the 90X2 for LTE-only coverage, FirstNet priority, or Canada.
- Is the 90X2 FirstNet capable?
- Yes. It supports band 14 and is AT&T FirstNet Trusted, which is what gives public-safety-adjacent sites priority and pre-emption on the network during an incident.
- How long does it run without mains power?
- The 18-cell 15Ah lithium-ion battery is rated for up to 48 hours of standby, with real runtime varying by line activity and load. A 12VDC 4.0A UPS output can power approved connected equipment from the same pack.
- Can it carry fire alarm and elevator phone lines?
- Yes. The 90X2 is aligned with UL 864 and NFPA 72 requirements for fire alarm signal transmission and is listed by the California State Fire Marshal under 7305-2384:0002. NFPA 72 is a code that applies to the installed system, not a product certification, so the authority having jurisdiction makes the final call on any given site.
- Whose FCC grant does the 90X2 carry?
- The FCC identifier on the 90X2 is a modular grant held by Quectel for the embedded cellular module, unlike the 90X1 which carries DataRemote’s own grant. We publish this because it is the kind of detail an AHJ or a procurement review will eventually ask about.
