Forward Error Correction (FEC) choices include Turbo Product Code (TPC), Viterbi, Reed-Solomon, and Trellis Coded Modulation (TCM)
Automatic Uplink Power Control (AUPC)
Embedded Distant-end Monitor and Control (EDMAC/EDMAC2)
Redundancy options
10 MHz reference for BUC, FSK communications and optional BUC power supply
10 MHz reference and power supply for LNB
Optional, integrated IP Module with 10/100 BaseT Ethernet port

Advanced IP Module Options

Header Compression – Configurable on a per-route basis, reduces the required Voice over Internet Protocol (VoIP) bandwidth by as much as 60%.

Payload Compression – Applied to the entire Layer 2 (Ethernet frame) or Layer 3 (IP datagram) packet optimizing traffic and reducing satellite bandwidth up to 40%.

Quality of Service (QoS) – Reduces jitter and latency for real time traffic, provides priority treatment to mission critical applications and allows non-critical traffic to use the remaining bandwidth.

Vipersat Management System (VMS) – Integrates with the powerful network management tool VMS. In addition to the traditional monitoring and control of the CDM-570/L-IP modem, CDD-564/L and CDD-562L demodulators, the VMS allows these devices to share bandwidth, and when needed, switch automatically to a dedicated SCPC channel.
