PCI Dial-Up Modem for Legacy Lines
The US Robotics USR5660A is a PCI bus dial-up modem designed for desktop PCs that still connect through analogue telephone lines. It suits home users who need basic internet access, fax capability or V.80 video conferencing on a V.92 56K connection.
Plug-and-Play Install with Common Pitfalls
The card uses a standard PCI slot and ships with a resource disk, RJ11 cable and manual for a three-step setup. Installers often forget to disable any onboard modem in BIOS, which creates a resource conflict, or they omit the telephone-line surge protector that the manual recommends.
Steady 56K Operation Within Line Limits
Under continuous use the modem holds to the ITU V.92, V.90 and V.34 standards with V.42, MNP2-4 error control and V.44, V.42bis, MNP5 compression. Real-world throughput stays bounded by the 56Kbps ceiling and the quality of the copper pair, so sustained sessions do not exceed the rated maximum.

Questions about this item
How do I verify the modem is operating at 56Kbps after installing the USR5660A?
Check the connection speed reported by your dial-up networking software; it should show a rate up to 56Kbps when the V.92 handshake completes successfully.
What comes with the USR5660A and what must I provide separately?
The box contains the modem card, a resource disk, an RJ11 cable, a manual and an accessory; you must supply a desktop with a free PCI slot and an active telephone line.
Which version of the USR5660A should I choose for V.92 call-waiting features?
The USR5660A is a single model supporting V.92, V.90 and V.34 standards, so the listed version already includes call-waiting and modem-on-hold capabilities.
