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.

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
for fading sensitivesatellites (X-, Ku-,
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.
