SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS

APPLICATION NOTE

IP TRUNKING

Satellite IP Trunking networks provide local

networks with access to the internet (or any other

type of network) from a remote access point to

the backbone. Providing IP Trunking & Backbone

services to ISPs and Telecom operators requires

constant scrutinizing of the operational expensesdue to a highly competitive market with razor-

thin margins.

Satellite service providers, teleports and

satellite operators that provide these services

are faced with new and complex challenges to

maintain their competitiveness, while remaining

profitable. Implementing new technical solutions

to deal with these challenges is more essentialthan ever. Flexible business models, delivering

the best Service Level Agreements and offering

Trunking services at competitive prices puts the

Service Providers back in the game.

The Newtec FlexACMimplementationdoubles the data throughput in IPTrunking and Backbone networks oversatellite at optimal availability.

APPLICATION NOTE

IP TRUNKING

Newtec introduces the FlexACMtechnology for IP Trunking

and IP Backbone networks over satellite at full efficiency.

These networks provide access to the internet backbone

(or other networks) for remote locations that are lackingterrestrial communication connectivity due to economical

reasons, natural obstacles or man-made/natural disasters.

The link over satellite between the remote location(s) and

uplink is established in a point-to-point or star (point-to-

multipoint) configuration through Single-Channel-per-Carrier

(SCPC) or Multi-Channel-per-Carrier (MCPC) technologies.

Newtec satellite hubs or modems are installed on each side

of the satellite link.

FlexACM combines the DVB-S2 standard with a set of

technologies in order to double the throughput over satellite in

the same bandwidth, with the capability to combine different

services (video, voice, data, internet access, VoIP, WiMAX,

GPRS, 3G, etc.) within the same satellite carrier.

Proven Return-on-Investment

The Trunking business is a highly competitive market

with continuous pressure on pricing and profitability. The

implementation of FlexACM translates directly into new

business opportunities for ISPs, Satellite Service Operators

and Satellite Operators. FlexACM increases the customer base

within the same bandwidth. At the same time it introduces

ways to reduce OPEX costs and increase the profitability of

your business. Resulting in a quick Return-on-Investment.

FlexACM combines DVB-S2 with different technologies to

get as much data through the same satellite bandwidth

as possible. FlexACM will auto-adaptively set modulation

parameters to the optimal point and overcomes distortion,

noise and variation in the satellite link. Newtec gets as closeto the zero margin limit as possible allowing the full use of

the satellite link.

Through FlexACM the data rates between uplink and remote

sites (for both Point-to-Point and Point-to-Multipoint

Networks) can be doubled in the same bandwidth without the

need to acquire extra satellite capacity.

Flexible Business Models

In a market where throughput rates are increasing significantly

and competition is fierce, the Service Provider must be able to

offer a flexible and affordable service to its customers to cope

with changing market conditions and still remain profitable.

Newtecs FlexACMHub brings the unique Bandwidth Manager

feature where both the IP and the satellite segment can be

shaped. Individual customers are flexibly added or removed from

the same network. Different services (Internet Access, VoIP,

etc.) can be combined in the same satellite carrier with separate

Service Level Agreement requirements and rate options. Both

Committed Information Rates (CIR) and Peak Rates are offered

in an adaptive satellite environment at various speeds. As a

business model risk mitigation the FlexACM Hub forward carriercan even be combined with Newtecs VSAT solution.

Whatever scenario the Service Provider faces, FlexACM allows

them to flexibly build business models dedicated to the providers

needs and profitability.

Newtec has the

unique ability to

offer Committed

Information rates (CIR)

in an adaptive satellite

environment.

Optimal Availability

Communication lines over satellite need to be available at all

time to exchange critical information and to keep customer

satisfaction at a high level. However, fading conditions

could seriously disturb the satellite transmission and lead

to temporary link losses. Fading conditions could be due

to different circumstances: the choice of satellite (Inclined

Orbit, Ku-, Ka- and X-band), environmental (rain, dust) or

interference (between two adjacent satellites).

Thanks to the auto-adaptive technology incorporated inside

Newtecs FlexACMthese fading conditions will no longer

interrupt the transmission between the hub and remote

sites nor result in the loss of data. In fading conditions

FlexACM will switch to a more robust modulation andprovide optimal availability. As soon as fading conditions

are over FlexACM technology automatically switches back

to maximum efficiency. During the entire operation it is

possible to sustain Committed Information Rates (CIR).

FlexACMoptimizes

the throughput

Ka-band) but also

for Inclined Orbit

Satellites.

Drive for More Throughput

Efficiency and more throughput are inherent factors for each

Newtec solution in IP Trunking and IP Backbone applications.

Dedicated technologies such as FlexACM, Bandwidth

Cancellation, Clean Channel Technology and LDPC address

a large set of IP Point-to-Point or Point-to-MultiPoint at rates

between 1.2 kbps to 160 Mbps. At each instance maximum

throughput is achieved.

Keep OPEX under Control

Newtecs FlexACM doubles the throughput of video, voice and

data over satellite. Which results in the fact that more data can

be transported in the same bandwidth or that space segmentrequirements can be cut by half if the same rates will be used

in future. Moreover, no extra or new ground infrastructure

(antenna or amplifier) needs to be acquired to enable the

higher data rates.

Dedicated

technologies such asFlexACM, Bandwidth

Cancellation, Clean

Channel Technology

and LDPC maximize

the throughput over

satellite.
