Teledyne Paradise Datacom PD155i DVB-S2 64QAM IP Satellite Modem Router
DVB-S2 FEC and modulation support, Data rates from 4.8 Kbps to 155 Mbps
PD155i DVB-S2 64QAM IP Satellite Modem Router
This product has reached end of life and has been replaced by the Q-Flex series modem.
Paradise Datacom PD155i Broadband Satellite Modem is 155Mbps capable and offers IP over DVB encapsulation and dynamic routing.
The PD155i is a 155Mbps IP satellite modem/router offering an extensive range of network management and bandwidth optimization features. A 4-port Gigabit Ethernet switch, advanced routing and Quality of Service protocols are supported as part of the feature-rich IP functionality.
Traffic shaping allocates bandwidth in a controlled manner between competing data streams. This allows data services – including the satellite portion of the link -- to be fully provisioned end-to-end rather than being simply ‘best effort’.
Large bandwidth reductions are achieved using a range of data compression and acceleration techniques. Paired Carrier (incorporating ViaSat’s patented PCMA technology) can further halve satellite bandwidth requirements.
State-of-the-art forward-error-correction (FEC) technology includes Turbo and LDPC. Low latency FastLink LDPC is attractive for low-data rate links. Single/multi-stream DVB-S2 (Digital Video Broadcast) is also supported.
Embedded satellite and IP diagnostic tools are included and are the most sophisticated available on the market. The PD155i is fully compatible with all other Paradise Quantum-series modems in IP closed modes.

Throughput Performance:
The maximum modem throughput depends on IP traffic format and the features enabled. Bridged IP/UDP data can be processed up to 155Mbps.
Routing and Bridging:
Bridging (standard).
Basic routing with static routes (standard).
Dynamic routing option: RIP V1 and V2; OSPF V2 and V3; BGP V4
TCP Acceleration:
Typical throughput level of 90% of link capacity.
5,000 concurrent accelerated TCP connection limit.
Includes HTTP Acceleration (prefetches webpage inline objects to reduce web page download times)
Header Compression Robust Header Compression to RFC 3095 profile 2 (IP/UDP). Reduces Ethernet/IP/UDP header sizes typically by
90%. 1-way packet processing limit: 58,000 pps; 2-way limit: 44,000 pps.
Traffic Shaping:
Provides guaranteed throughput levels for specific IP streams, using standard CIR and BIR settings.
Stream differentiation:
By IP address, IEEE 802.1p priority class, Diffserv DSCP class or MPLS EXP field
VLAN Support
IEEE 802.1q VLAN support (standard)
IEEE 802.1p Quality of Service (packet prioritisation) using strict priority or fair weighting queuing
DHCP,
SNMP DHCP (standard). SNMP (standard) v1, v2c and v3
Web Server:
Standard. Embedded web server (standard) M&C interface
IP Diagnostic Graphs:
Standard. Shows throughput (bps, pps); dropped, errored packet counts
IP over DVB Encapsulation/Decapsulation:
Supports MPE, ULE and Paradise PXE. Includes MPE air MAC address filtering
DVB-S2 IP Multistreaming:
Point-to-multipoint CCM and VCM multistreaming. VCM allows the FEC error correction to vary for each remote
IP Address Aliasing:
Standard Allows IP ports to exist on multiple subnets at the same time
DVB-S2 ACM Dynamically varies point-to-point FEC strength and throughput, maximising throughput for the actual link conditions
DVB-S2: QPSK; 8PSK; 16APSK, SCPC: BPSK; QPSK; OQPSK; 8PSK; 8QAM; 16APSK, 16QAM, 32APSK, 64QAM
