The Data Connect MD28.8 is Bell V.32bis modem designed for asynchronous operation at 0 to 14400bps over voice grade lines. The modem is intended for use on 2-wire or 4-wire leased lines. The MD28.8 is compromised of MDMC carrier and PE14.4 module.  Up to 18 MD28.8can be front loaded into and MDR Modem Bank. The MDR Modem Bank is an industrial grade 19” x 3U rack mountable chassis. The MDR Modem Bank is powered from wide range of AC or DC voltages. Two power supply cards can be installed to provide automatic back up in the event the primary power supply fails. The MDR will operate in temperatures from 20°C to +85°C is surge protected on both power and analog lines. Two power supply slots are provided. Power supply cards are available for any voltage in the range 9-150VDC and 9-275VAC. A single power supply card will power all 18 MD28.8. In addition to the MD28.8 the MDR Modem Bank also houses the MD14.4L, MD14.4, MD9.6FPD, and MD202T
