If you can make a phone call, it generally works acceptable enough for a basic SSH session. Lock the session at 1xrtt (if using CDMA) if you still have problems (slow) and it will use what amounts to a voice channel. In the USA, Verizon 4g LTE also offers some better in-building penetration simply due to the spectrum used (700mhz).
On the 3g deployment I did, I built an ipsec vpn to the provider and have a private IP assigned directly to the cellular device instead of individual VPNs per-console server. As for Equinox in particular, you might be able to use the house wifi instead for your VPN... Many vendors have 3g/wifi console servers (or both) that auto-vpn home. I can't see a good reason to use analog lines anymore unless 3g isn't serviceable at the location. If you can't afford a 3g device, you can roll your own with any cheap router running DD-WRT or OpenWRT + usb ports + usr/serial dongles. Use "ser2net" to handle the interface between TCP and a serial port (but one could connect and use screen/whatever if they wanted).
