Dual RJ11 USB Modem

The EN-Labs U2FAXMOD is a USB 56K data, fax and voice modem with two RJ11 ports for telephone and fax line connections. It uses a Conexant chipset and complies with V.90 and V.92 standards for dial-up communication.

Home offices needing legacy dial-up

This modem suits users who must maintain a landline fax or dial-up internet connection on Windows systems from 98 through 10. It is not for buyers who need broadband speeds, Ethernet connectivity or modern VoIP integration.

Sustained 56K operation

Under continuous use the modem maintains up to 56Kbps download and 48Kbps upload with V.42 and MNP error correction. Auto-retrain and Modem-on-Hold features keep the link stable during long sessions without speed negotiation drops.

Questions about this item

What type of telephone line must I already have for the EN-Labs U2FAXMOD 56K USB Modem to work?

The modem requires a standard analogue telephone line with an RJ11 wall socket; it connects via the supplied RJ11 cable to one of the two RJ11 ports on the device.

Can I keep my existing analogue telephone or fax machine connected while using this modem?

Yes, the second RJ11 port lets you plug a telephone or fax machine in parallel so both devices share the same line.

How can I verify the modem is operating at its rated 56K download speed after setup?

Check the connection status in your dial-up networking properties; it will display the negotiated line speed, which can reach up to 56Kbps download and 48Kbps upload depending on line quality.
