(GSM) backhaul to replace T1/E1 and other ground-based
base transceiver station-to-base station controller (BTS-to-
BSC) network elements.

IP multicasts
– The HX gateway supports IP multicasts to
send multimedia or other traffic to multiple remote sites
simultaneously, and HX satellite routers include IGMP
support to route IP multicast traffic to attached workstations.
•
Border Gateway Protocol
- BGP is a routing protocol
frequently used with MPLS networks. Utilizing BGP, the HX
now offers a more seamless interface to the networks.
HX System architecture
The HX system provides star TDM/TDMA connectivity
consisting of a central gateway connecting to multiple HX remote
terminals. With a DVB-S/DVB-S2 outbound carrier supporting
rates up to 121 Mbps and multiple inbound carriers supporting
rates up to 3.2 Mbps, the HX system provides the high throughput
needed for high QoS networking.
HX System star topology
The HX system star-topology network has the following major
elements, the HX gateway and the HX satellite routers.
HX gateway
The HX gateway is the central processing center of the network.
The gateway provides connectivity between HX satellite routers
and customer data centers and/or the Internet.
The HX System supports two types of gateways:
•
Fixed gateway
•
Transportable gateway
Fixed gateway (GW)
The fixed gateway equipment is contained in one or more racks
that are in a fixed location.
The majority of this manual refers, by default, to the fixed
gateway system.
Transportable gateway (TGW)
The transportable gateway equipment is contained in a single rack
that can easily be packed, moved and reassembled.
The system is well suited for applications where network
transportability is critical - including homeland security,
continuity of operations, tactical military, and remote news
gathering. At only two feet in height, the system is a size and
