L-band Matrix Router: XRM 2250          

The XRM 2250 L-band Matrix Router features a unique architecture 3-stage which provides redundant RF signal paths and automated re-routing in the event of a crosspoint fault. The system automatically routes around the fault using an alternate path in the XRM module and sends an SNMP trap to alert the operator. A complete 32x32 L-band matrix, including hot-swappable input, output and bridge cards, redundant power supplies, and system controller is contained in a 6 RU chassis. The user can easily access cards for upgrades and maintenance via front panel without disconnecting cables or disrupting the signal paths of the other cards in the system. This permits seamless online upgrades and maintenance. The modular design permits a wide variety of configurations which can be easily expanded.

XRM System Architecture

Each XRM L-band Matrix System larger than 32x32 is made up of one or more system modules. System modules include XRD Input distribution modules, XRM Matrix Switch Modules and XRO Output Switch Modules. The number and types of modules depends on the desired number of inputs and outputs. the RF signals pass through no more than three modules, regardless of the system size. XRD..XRM..XRO.

 

 

Features & Benefits

• 3-stage RF matrix switch architecture with multiple redundant RF paths for automated re-routing in the event of a crosspoint fault

The XRM Matrix Router is a full fan-out, non blocking matrix switching system. In a typical broadcast-network, satellite teleport, cable headend or earth station application, it gives the user the ability to reroute any of the L-band signals from the dishes to be routed to any or all outputs of the router typically connected to a satellite receiver or a modem. The Matrix Switch provides flexibility to the networks and allows reliabile routing eliminating costly down time from signal failure.
