Description

The MD202T is rackmount version of the MIU202T. The same functionality that can be found in the MIU202T can be in the MD202T.

The MD202T is a Bell 202T modem designed for asynchronous operation at 0 to 1200bps over voice grade lines and private lines and provides half-duplex communication on 2-wire lines, or full duplex on 4-wire lines.

The MD202T is comprised of MDMC carrier card and PE202T module. Up to 18 MD202T can be front loaded into 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 and surge protected on both power and analog lines.

Two power supply slots are provided. Power supply cards available for any voltage in the range 9-150VDC and 9-275VAC. A single power supply card will power all 18 MD202T.

In addition to the MD202T the MDR Modem Bank also houses the MD28.8, MD14.4L, and MD9.6FPD.
