IP TRUNKING - Newtec

IP Trunking and IP Backbones over Satellite

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 and

Backbone services to ISPs and Telecom

operators requires constant scrutinizing

of the operational expenses due 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. Technical solutions to deal with

these challenges and to increase efficiency over satellite is more essential than

ever.

Flexible business models based on DVB standards for satellite communications,

delivering the best Service Level Agreements and offering Trunking services at

competitive prices puts the Service Providers back in the game.www.newtec.eu

Newtec’s professional satcom equipment is based on

DVB standards. Kick-started by Newtec, key players in the

satellite industry have called for a new satellite transmission

standard (DVB-S2X) to extend the existing DVB-S2 standard,

specifically for professional satellite links.

Open standards such as DVB-S2 and DVB-S2X allow for

interoperability and avoid vendor lock-in. Moreover

they increase the profitability of the industry by creating

an economy of scale and reducing the cost of satcom

equipment.

As forerunner to the standard, Newtec launched its own

S2 Extensions during 2013 in order to prove the different

techniques that were proposed for the standard. These

proprietary S2 Extensions will keep on being supported for

closed networks.

The S2 Extensions provide gains up to 37%, the new DVB-

S2X standard (that even has 256APSK support) will increase

this gain even more up to 51%. These gains exceed the

results by proprietary systems in the market.

For Newtec DVB-S2 modems and modulators (Elevation &

Azimuth) already deployed in the field, Newtec provides

Clean Channel Technology™ as a software field upgrade.

As such Newtec customers can immediately benefit up to

15% gain compared to DVB-S2 through implementing a

lower Roll-Off factor (5/10/15%) and an advanced filtering

technology.

Efficiency is at the core of Newtec technology in Trunking and

Backbone networks. Record-breaking speeds up to 506 Mbps

are achieved over a Ku-band 72 MHz satellite transponder at

optimal service availability.

Newtec satellite hubs or modems are installed on each side of

the satellite link. Networks in Point-to-Point, Point-to-MultiPoint

(star) or Multiple Point-to-Point configuration are supported

through Single-Channel-per-Carrier (SCPC) or Multi-Channel-

per-Carrier (MCPC) technologies. Within the same carrier

different services such as data, video, voice, internet access,

VoIP, WiMAX, GPRS, 3G/4G can be aggregated.

Newtec technology is based

on DVB-S2, DVB-S2X and

S2 Extensions and combines a

set of innovative technologies

in order to fully optimize

the Trunking and Backbone

links. These technologies

are FlexACM®, Cross-Layer-

Optimization™, Clean Channel

Technology™, Automated Equalink®, Automatic Uplink Power

Control (AUPC), Bandwidth Cancellation and Wideband up to

72 Mbaud.

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, DVB-S2X and S2 Extensions

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 close to 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. As such a quick

Return-on-Investment can be achieved in a matter of months.

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

Newtec’s FlexACM® these 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 and provide optimal

availability. As soon as fading

conditions are over FlexACM

technology automatically switches

back to maximum efficiency.

Moreover service priorities (e.g.

video, data, voice) and Quality-

of-Service policies can be auto-

adapted on-the-fly depending

on the bandwidth availability through Newtec’s Cross-Layer-

Optimization™ technology.

Optimal Service Availability

FlexACM® optimizes the

throughput for fading sensitive

satellites (X-, Ku-,Ka-band) but also for Inclined Orbit

Satellites.

Newtec is the only player in the satellite market that can provide

different flavors of adaptive modulation and coding (ACM) which

enables the service provider to adapt their Trunking Point-to-

MultiPoint network to their preferred business model.

Newtec FlexACM technology provides Committed Information

Rates in highly adaptive satellite bandwidth environments for

services such as video, VoIP or for customers

demanding a fixed throughput at all times.

The FlexACM Fixed Rate Flavor provides up

to 70% gains compared to VCM (Variable

Modulation and Coding) networks.

Committed Information Rates in Adaptive Environments

Customer Quote: ‘Newtec turns Ku-band into C-band’

FlexACM Independent Rate:

• Fading at remote site 3 (8PSK) does not affect

the throughput and bandwidth of the other sites

• The sites are only influenced by their own

fading conditions.

• Not fit for fixed rate services.

FlexACM Fixed Rate:

• Fading at remote site 3 (8PSK) does not affect the

throughput and bandwidth of the other sites.

• A buffer (margin) compensates for any fading situation

across the network through statistical multiplexing.

• Customers can get Committed Information Rates (CIR),

even in adaptive environments for VoIP or Video etc.

• Rest of symbols (bandwidth) can be distributed over

network (PIR or Peak Information Rate)

FlexACM Shared Rate:

• Fading at remote site 3 (8PSK) affects the throughput

and bandwidth of the other sites

• ACM ‘shared’ scenario is ok if all remotes are part of

a same network.

• Not fit for fixed rate services.

• ACM version applied by majority of the market today

In a market where throughput rates are

increasing significantly and compe-

tition is fierce, the Service Providers

must be able to offer a flexible and

affordable service to their customers to

cope with changing market conditions

and still remain profitable.

Newtec’s HUB6000 and EL501 Hubs

house 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 (SLA) requirements and rate options. Both

Committed Information Rates (CIR) and Peak Rates are offered in

an adaptive satellite environment at various speeds.

Whatever scenario the Service Provider selects, the Bandwidth

Manager allows to flexibly build business models dedicated to

the provider’s needs and profitability.

Through the Newtec Dialog hub both service providers, B2B

and B2C VSAT customers are connected with a common forward

satellite carrier. The return technology can be SCPC, MF-TDMA or

the Newtec patented Mx-DMA™ technology depending on the

return rates, the size of the remote or the network configuration.

Mx-DMA or Cross-Dimensional Multiple Access is the return

technology that incorporates the best features of MF-TDMA

and SCPC technologies and at the same time solves the difficult

choice to select either of them.

By aggregating the data traffic in a common forward carrier and

combining equipment in a single hub, important CAPEX and

OPEX savings can be made. Extra bandwidth gains are achieved

by implementing FlexACM, Clean Channel Technology

and Cross-Layer-Optimization technologies on top of the

multiservice network.

In order to mitigate the risk

of a slow take-up of VSAT

services, the service provider

can compensate revenue

with the fast (temporarily)

uptake of Trunking demands

on the same capacity. The

multi-service network also

allows the service provider

to provide IP access services

in a direct way (VSAT) or

an indirect way (Backhaul,

WiMAX, Trunking) to the end user.

Multiservice Networks

The Newtec’s Multi-service network model

provides the service provider with a

pro-active and flexible business model that allows him to scale

between Trunking and VSAT capacity.
