Radyne ComStream DMD2401 LBST L-Band Satellite Modem and ODU Driver IF

The Radyne DMD2401 LBST Modem is a fully-integrated, high-performance system designed to support Ku- or C-band satellite single-channel-per-carrier (SCPC) links or as a VSAT remote site modem in a TDMA hub system. It provides reliable, cost-effective data communications in applications requiring continuous transmission and reception.

The DMD2401 LBST multiplexes the Tx IF, DC voltage and 10 MHz reference frequency onto the Tx and Rx IFL coax cables. This architecture allows the DMD2401LBST to interface with Ku- or C-Band block up converters (BUC) and low noise blocks (LNBs). By directly connecting to the L-Band input of a BUC and the output of an LNB, normal, expensive transmit and receive converter equipment is eliminated.

The DMD2401 LBST offers fully programmable options and parameters. Operating parameters, such as variable data rates, FEC code rate, modulation type and IF frequencies can be readily controlled and monitored via the front panel or RS-485/-232 serial control channel located on the rear panel.

Available options for the DMD2401 LBST, such as Turbo Product code or Reed-Solomon, are available for applications requiring bit error rates of 1x10 -10. IBS and IDR options are also available, which comply to IESS 308/309/310. These options include features such as Drop and Insert, Asynchronous Channel, Engineering Channel (ESC),
and Automatic Uplink Power Control (AUPC) which allows the user to monitor and control the distant end. These options are supported by the synchronous data interface RS-232/-449/V.35 or G.703 Balanced or Unbalanced T1 and E1 data rates.
