Ethernet Traffic
Throughput Performance The maximum modem throughput depends on IP traffic format and the features enabled. Bridged IP/ UDP data can be processed up to the modem maximum data rate. Please seek assistance from Paradise Datacom in evaluating your particular requirements.
Routing and Bridging Bridging (standard).

Static routing (standard).

Dynamic routing option: RIP V1, V2; OSPF V2, V3; BGP V4
TCP Acceleration Option Typical throughput level of 90% of link capacity.

Supports 5,000 concurrent accelerated TCP connections (plus at least 35,000 unaccelerated TCP connections) up to the modem maximum data rate.
Header Compression Option Robust Header Compression to RFC 3095. Reduces Ethernet/IP/UDP/ TCP/RTP header sizes typically by 90%. 1-way packet processing limit: 60,000 pps; 2-way limit: 45,000 pps. Includes Ethernet header compression (compresses 14-byte Ethernet frame to typically one byte)
Payload Compression Option Uses Deflate algorithm (RFC 1951) to compress all TCP/IP packets (TCP and UDP), typically resulting in compression of payloads by 50%
Traffic Shaping Option Provides guaranteed throughput levels for IP streams, using Committed Information Rate and Burst Information Rate settings. Stream differentiation is by IP address, IEEE 802.1p priority class, Diffserv DSCP class or MPLS EXP field
Encryption Option Encrypts all IP traffic using AES with 256-bit keys
IPv6 Provided as standard. Dual IPV4/ IPV6 TCP/IP stack allowing use of both IPv4 and IPv6 addresses for bridging and routing of traffic
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) for automatic allocation of M&C IP address. SNMP (standard) v1, v2c and v3
Web Server Embedded web server M&C interface (standard)
IP Diagnostic Graphs Shows Tx, Rx throughput (bps, pps); dropped, errored packet counts (standard)
IP over DVB Encapsulation Option Supports encapsulation/ decapsulation of MPE, ULE and Paradise PXE
DVB-S2 ACM Option Dynamically varies modcod with varying link conditions, maximising throughput at all times by converting unused link margin into additional throughput
ODU facilities via IF interface
FSK Control Allows monitor & control of a compatible L-band BUC or IF Transceiver from the modem via the Tx IFL cable
Paired Carrier
Paired Carrier Transmit and receive carriers are overlaid on top of each other in the same space segment. Echo cancellation techniques are used in the demodulator to cancel the transmit carrier and extract the wanted receive carrier signal
Paired Carrier data rate options 256kbps, 512kbps, 1024kbps, 2.5Mbps, 5Mbps, 10Mbps, 15Mbps, 20Mbps, 25Mbps, 30Mbps, 40Mbps, 50Mbps, 60Mbps, 80Mbps, 100Mbps and 155Mbps traffic rate

(30kHz to 54MHz occupied bandwidth)
Power asymmetry -10dB to +10dB
Symbol rate asymmetry Up to 12:1
Eb/No degradation Typically < 0.5dB (0.7dB for 16QAM/16APSK with 10dB power asymmetry)
Mobile Operation Uses GPS data to continually recalculate position relative to satellite, allowing uninterrupted operation in mobile environments (ships, etc.) anywhere in satellite footprint
Drop & Insert Option
Bearer Types T1-D4, T1-ESF, E1-G.732
Timeslot Selection Independent selection of arbitrary timeslots for both drop and insert.
Bearer Generation Terrestrial bearer may be looped through modem, or terminated after Drop Mux and a new bearer generated by the insert Mux
Timeslot ID Maintains the identity of individual Drop/Insert timeslots for N=1,2,3,4,5,6,8,10,12,15,16, 20, 24 and 30. (See extended option below)
Extended Drop & Insert Option
Multi- Destinational Working All or only a subset of the received data may be inserted into the terrestrial bearer on the receive path for multi-destinational working
Timeslot ID Maintenance The framed service is extended to maintain the identity of individual timeslots for all values of N from 1 to 31
Signaling CAS and RBS are fully supported
Advanced ESC
ESC/Aux Port Provides high-rate async ESC or Intelsat low-rate async IBS ESC
Electrical Interface IP, RS232, RS422 or RS485
Async ESC Closed Net Plus ESC: Overhead scales to any ESC baud rate from 0.5% to 70% of the main channel rate

IBS Option: High-rate async channel (1/32nd to 2/32nd of the IBS overhead) providing async baud rates from 0.2% to 5.1% of the terrestrial rate
Advanced Aux Intelsat low-rate async ESC carried In bit 1 of TS32 providing a synchronous channel at 1/480th of the data rate, allowing up to one quarter of this rate for over-sampled async data
