ArrangeLink

ArrangeLink is used to schedule network resources in support of a variety of critical applications including distance learning, video

conferencing, news and sporting event video streaming, and scheduled broadcasting. Circuit assignment schedules can be created and

executed based on circuit type, start/end date/time, transmission data rate, transmitter node, and receiver node. These schedules and

their details can be viewed using user-defined filter sets. The ArrangeLink event log provides a generated report for network analysis with

totals for successful, failed, and pending schedules.

ViperGlobe

ViperGlobe is an optional global network view application that is installed on VMS

Client machines. The ViperGlobe option greatly enhances management

capabilities by providing a geographical global representation of the Vipersat

satellite network. ViperGlobe displays the networks that are created under the

Network Manager and provides a visual global positioning of the network sites

and the carrier links that exist between them. Network alarm status is also

visually indicated in the globe view.

The operator can now anchor sites to true geographic locations. In a satellite on-

the-move network, mobile sites are positioned based on GPS information

received from the antenna control unit (ACU).

Total System Redundancy

We offer fully automated redundant hardware and software for both hub and remote

locations. Our solutions can be placed online without personnel intervention, preserving

the link and maintaining transmission of your mission-critical data.

 VMS redundancy provides automatic backup (N:1) with one primary and virtually

unlimited geographically dispersed redundant servers.

 Hub outbound modem redundancy requires the hub redundancy feature and an

Ethernet-controlled power strip; offers an N:M configuration where multiple outbound

modems can be backed up by any number of spare modems.

Remote modem redundancy – requires hardware i.e. CRS-311, CRS-170A, CRS-180;

offers a 1:1 configuration where a single modem is backed up by an online redundant

modem.

Multi-Transponder Operation

Finding contiguous bandwidth can be a challenge when bandwidth requirements increase, often month or years after the initial purchase.

VMS allows for any number of noncontiguous bandwidth pools to be allocated for dSCPC purposes. This provides you with the freedom to

purchase less expensive, noncontiguous bandwidth to support growing network needs.

Satellite Cross Strapping/Banding Support

Due to various technical and financial factors, it is often required to use cross strapped, or cross banded satellite resources. Cross

strapped transponders are often used in spot beam configurations where the satellite bandwidth provider has created a situation where a

node is unable to see its own transmission on the receive side of the satellite link. This is often done for performance gains in what would

otherwise be the edge of the satellite footprint locations.

Cross banded transponders use the same principle, but will have one side of the transmission Ku-Band and the other side C-Band. This

type of satellite topology is often found over areas where the hub facility is in a superior rain fade area compared to the remote terminal

location.

VMS provides the capability for applications involving satellite cross banding (cross strapping). This feature allows for greater flexibility

when acquiring satellite bandwidth.

Active Distribution List

Distribution Lists provide the ability to define multiple receive locations in which the operator intends to include in a pre-defined

transmission type such as multicast video distribution. The VMS is a transmission carrier management server; this means the

transmission device is the device capable of asking for resource changes. However, often in the case of outages, a receiver needs to

inform the VMS it is back online and needs to be recovered in any ongoing mesh connection with which it may be associated.

Active Distribution Lists actively monitor all dynamic mesh connections for outages at either side of the link. Upon detecting a failure, the

VMS will place the failed demodulator in recovery mode, attempting to recover the circuit every 60 seconds.

On-Demand Mesh Connection

Until now, flexible and dynamic switching systems such as DAMA or multiple transmission link switches were bandwidth and equipment

resource intensive. This was due to the constraints of traditional private serial modem interfaces. Switching multiple transmission links via

satellite meant reducing flexibility for the benefit of lower latency circuit switches. On-demand mesh connection technology offers mesh
