1037852-0001 Revision A
• Increased inroute capacity per rack space (up to 9 inroutes for
1U of rack)
• Supports higher symbol and user data rates
• Fully managed by NMSS
While the introduction of CDS is an upgrade, HX systems
continue to support IFSS-TC, as well.
CACTI Network Manager
CACTI Network Manager (new installations only) provides for
network monitoring, event logging, and graphing SNMP
statistics. Templates for network devices are included with this
feature.
Expansion rack option
An expansion rack option has been added to the HX System fixed
rack model.
The HX System
The HX System is an innovative IP broadband very small
aperture terminal (VSAT) system created by Hughes. The system
is designed and optimized for smaller networks that require
high-bandwidth, high-quality of service (QoS) links. The HX
System leverages the best features and capabilities of the proven
Hughes HN broadband VSAT system - with over one million
terminals deployed - while providing new features that support
high-bandwidth, real-time applications such as telephony
trunking, video conferencing, and much more.
The most significant upgrade with the HX 1.2.7 over previous
models is the inclusion of the mobility feature. While mobile
satellite services at lower satellite frequencies (L-band, in
particular) have been available for some time, these services tend
to provide lower rates of speed (up to 400 kbps) and tend to be
very expensive. With the HX 1.2.7, mobile satellite broadband
using higher frequency services, such as Ku-band, now provides
more bandwidth at a much lower cost.
The HX System’s advanced bandwidth-management features
enable operators to customize fine-grained QoS and SLAs
(service level agreements) on a per-satellite router basis. For
example, HX System operators can guarantee both inbound and
outbound bandwidth per satellite router. In addition, the HX
System can provide dynamic bandwidth allocation for
time-division multiple access (TDMA) channels based on usage
and need, allowing development of a wide range of service plans
fine-tuned to meet individual needs. By leveraging the DVB-S2
transmission standard for the outbound channel, the HX System
