The Data Connect MD14.4L


The Data Connect MD14.4L is the Rackmount version of the Data Connect MIU14.4L and MIU14.4L-LV. The same functionality that can be found in the MIU14.4L and MIU14.4L-LV can be found in the MD14.4L. The Data Connect MD14.4L is a Bell V.32bis modem designed for asynchronous operation at 0 to 1400bps over voice grade lines. The modem is intended for use on 2-wire or 4-wire leased lines. The MD14.4 is comprised of MDMC carrier card and PE14.4 module. Up to 18 MD14.4 can be front loaded into a 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 temperature from -20°C to +85°C and 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 MD14.4L. In addition to the MD14.4L MDR Modem Bank also houses the MD28.8, MD14.4, MD9.6FPD, and MD202T.
