IBM 7857-017, 19.2 BAUD Modem (Used)
The IBM 7857 19.2 Kbps, V.32 bis Modem, with LPDA-2 configuration setup, represents the next generation of high-speed dial stand-alone modem technology. This technology places the new modem among the highest speed dial-up/leased-line modems currently available on the market. The 7857 modem operates over 2-wire dial-up and 2-wire or 4-wire leased analog circuits. It provides extended data rates up to 19.2 Kbps (Kilobits per second) in full duplex and clear asynchronous environments. The modems communicate with CCITT V.32 bis, CCITT V.32, CCITT V.22 bis, and CCITT V.22 (at 1.2 Kbps) modems. The IBM 7857 19.2 Kbps, V.32 bis Modem provides a cost-effective means to transfer data at high speeds over switched or leased analog circuits. The 7857 modem is a key element for business solutions in data transmission environments.
