IBM 7858-336, 33.6 KBPS Modem (Refurbished)
The IBM 7858 is a Professional Modem with LPDA-2 configuration setup and represents the next generation of high-speed, stand-alone, modem technology. This places this IBM modem among the highest symmetrical speed dial-up/lease-line modems currently available on the market. The IBM 7858 Professional Modem is a follow-on product of the IBM 7857 V.32bis Modem and is based on an equivalent architecture to maintain the maximum compatibility between the two modems. It has a professional- prone functionality, but it adds the support of the globally established ITU V.34 recommendation.
