NoteWorthy 56K Modem PC 3Com Card PCMCIA PC 3Com/Megahertz model 3CXM056-BNW
NoteWorthy 56K Modem PC Card (such as the 3Com/Megahertz model 3CXM056-BNW) is a vintage PCMCIA Type II expansion card used to give older laptop computers dial-up internet and fax capabilities.

XJACK Connector: Features a clever, retractable RJ-11 telephone jack built straight into the card. This design lets you plug a standard phone cable directly into the card without needing a loose external dongle or adapter cable. [1, 2]

PCMCIA Form Factor: Fits standard Type II PCMCIA slots on late-1990s and early-2000s notebook computers (like IBM Thinkpads or HP OmniBooks).

Dial-up Speeds: Operates at speeds up to 56Kbps for downloading data over standard analog landline telephone systems.

Digital Line Guard: Protects the internal circuitry by detecting and alerting you if you accidentally plug into a high-voltage digital PBX office phone line instead of an analog line.
