PowerEdge Main ComponentscPCI Management

The cPCI Management card is used for managing the

cPCI cage. It communicates with all the cards via the

cPCI internal bus

The cPCI cage is fully redundant. Each card is connected

to both Switch blades

19

Voice Packets Processor (VPP)

Routes of voice packets between VSATs (receivers) and media gateway

Sends voice packets directly to IPE

DAMA Call Allocation Server (DCAS)

Receives requests for satellite voice recourses from VSATs & VPP and sends the requests to the CSRM at the HSP

Data Protocol Server (DPS)

Interfacing the user servers at the hub side

Full IP protocol support & performs TCP acceleration

Hub Satellite Processor (HSP)

Centralized satellite resource manager (CSRM) for data and telephony inbound traffic

The HSP is connected to the following components:

The HSP card works with the following sub-components:

Hub Receivers Unit (HRU)

Synchronization Device

The Hub Receivers Unit and the Synchronization Device are managed by

the HSP and their software is downloaded from the HSP using TFTP

21

PowerEdge Main Components Data Protocol Server (DPS)

The DPS serves as an interface between the customer’s IP network

and the SkyEdge satellite network

It connects on one side to the customer’s IP network, and optionally to

the internet, and on the other to the HSP/IPE

PowerEdge Main Components Dynamic Call Allocation Server (DCAS)

The DCAS is a Dynamic Call Allocation Server for the

SkyEdge system - It functions as a satellite telephony switch

There is one active DCAS per network

The DCAS is responsible for:

Call handling

Communicating with the CSRM for resource allocation

Number manipulation

Call Data Records (CDRs)

PowerEdge Main Components Voice Packets Processor (VPP)

The VPP is the voice packet handler of the SkyEdge system

The main function of the VPP is to route voice packets between

VSATs & Media Gateway for calls from/to the PSTN, or between the

VSATs (in double hop)

Hub Receiver Unit (HRU)

The Hub Receiver Unit (HRU) processes Inbound signals and transmits

them over the LAN to the HSP, DPS or VPP

The HRU is a VME-bus chassis composed of:

A Controller card

Up to 18 inbound Receiver Cards

A Power splitter panel

Up to 6 receiver cages per HSP:

The receivers support GMSK Modulation

2 receivers per board

Maximal receiver rate is 840ksps

The HRU is connected to the following components:

Sync Device, HSP, VPP, LNB down converter splitter panel

25

Synchronization Device

Inbound transmission is based on slotted ALOHA, mandating VSATs & HUB synchronization to a common time base

The Synchronization Device sends synchronization signals to the VSATs & the HRU

The Sync device is connected to the following components:

Data LAN

IP Encapsulator (IPE)

The IP Encapsulator (IPE) receives IP packets and converts them into MPEG2 transport stream

The IPE uses two types of encapsulation:

MPE (Multi Protocol Encapsulation) for user data and system control

Data piping for the voice packets

Modulator

The Modulator receives the MPEG2

transform stream from the IPE and

converts it into a DVB-S modulated stream

It is also responsible for the Outbound

Forward Error Correction (FEC)

Newtec:

QPSK modulation

Agile 70MHz IF output

FEC Code Rates: 1/2, 2/3, 3/4, 5/6, 7/8

Symbol Rate: 256 Ksps to 30 Msps

Media Gateway

The Media Gateway is the main interface of the SkyEdge

network with the terrestrial telephony network.

Located at the hub and equipped with an E1 interface, the

Media Gateway supports up to 30 simultaneous calls.

As many as 256 Media Gateway units can be supported by

the SkyEdge hub.
