HMS Protocol Modem Card
The Model MB-HMS is an intelligent RF modem card designed to communicate to any HMS compliant transponder in an HFC network. In typical installations, the MB_HMS is installed in AM’s Hybrid Management Termination System, commonly called the “BridgePort™ HMTS”. The MB-HMS modem card and the BridgePort™ HMTS work t o g e t h e r a s a n integrated polling device to exchange SNMP data between the HMS field transponders and the Element Management System (EMS) like Omni2000™ or the Network Management System (NMS). Each MB_HMS has one frequency agile transmitter (48 MHz to 162 MHz) and 2 integrated receivers (5 MHz to 42 MHz) designed to further improve data communications. The MB_HMS also supports AM’s 9170 RF Addressable Switch, which extends the FSK RF Receiver’s two port capability to 16 ports (2x8) to further mitigate the build-up of noise, which facilitates the cost effective scalability of the BridgePort™ HMTS. If one system segment becomes excessively noisy, AM’s HMTS will continue to operate on the remaining system segments without impairment. Both receivers as well as the transmitter are frequency agile. The operating frequency of the MB-HMS, as well as the frequency of all the transponders it controls, is easily changed from an Omni2000TM software screen. The MB-HMS is designed to communicate with any HMS transponder and complies fully with SCTE 25-1 (formerly HMS-005) PHY Layer and SCTE 25-2 (Formerly HMS 004) MAC Layer. Other proprietary versions of the modem card are compatible with non-HMS communication protocols used by AM Networks and other status monitoring equipment suppliers.
