The DMDVR20 LBST is based on the proven design and technology of the DMD20 Universal Satellite Modem and the DD240 professional grade MCPC satellite demodulator with industry leading reliability.The DMDVR20 LBST is ideal for high quality private networks requiring low latency and low jitter transmission.

With its ability to support asymmetrical link operation with IESS compliant transmission and LDPC reception, the DMDVR20 LBST can receive large shared TDM carriers and provide small to medium sized return carriers for data/voice/video applications in a hub and spoke environment. DMDVR20 LBST is one of the most advanced remote site terminals in a single one rack unit size.
