For customers who may not have a suitable location for a hitching post or may want to be independent of terrestrial facilities, a satellite solution may be appropriate. Using a combination of portable generators and satellite communications allows for a Mobile Recovery solution to take place anywhere. Power in the form of diesel generators can be provided.

In partnership with Globecomm Systems Inc. (GSI) and NetSat Express, Inc. (NSX), Agility has engineered and deployed a sophisticated satellite recovery capability. GSI operates an International Teleport located on Long Island, NY, which also houses an AT&T Point-of-Presence. This recovery capability can support a combination of voice and data over three T1 circuits providing for up to 192 voice circuits per T1 for a total of 480 seats when fully deployed.

Combining satellite voice and data over IP is achieved by sophisticated compression techniques and Quality of Service (QoS) technology provided by Cisco Systems. Through the use of this technology, a voice channel requires only 8 kbps of bandwidth when active. The QoS technology further guarantees that voice will receive priority over data in order to minimize delay and efficiently share bandwidth between voice and data.
Mobile satellite configurations can be deployed in two ways. First is through the use of the GSI Teleport facility, which is connected to a number of terrestrial services. This configuration is outlined in figure 11 and will support both voice and data functionality. The second configuration is a Point-to-Point capability, which can link two customer locations via satellite T1. This configuration would typically be used for data only, unless pre-engineered for voice capability utilizing customer equipment.

The recovery solution shown in figure 11 provides for a turnkey voice and data capability, which can support up to 384 voice connections (192 per T1). The voice connections are connected to the Public Switched Telephone Network at the Teleport facilities in Long Island, NY via 16 T1 lines. Connectivity between the Teleport and the customer facilities or other recovery facility can be via either dedicated circuits engineered in advance or ISDN dial lines currently in place. In addition, provision can be made for Internet or VPN access through the Teleport facility.

Connectivity |
The Point-to-Point solution shown in figure 12 can be utilized where a customer requires a T1 capability but will provide for all other communication equipment. This is best deployed in a data only situation to connect a mobile solution to a corporate recovery facility. Voice requirements would require custom engineering in order to validate compatibility with Satellite technology.
