HDM100 H Management modem
The HDM100 H is a management modem with HMS compatibility. The module communicates with HFC network transponders via its RF modem, maintains a list of transponder statuses, manages the data link and provides IP connectivity between element/network management system and transponders.
HDM100 is available in two software versions: HDM100 H and HDM100 T. The versions are field interchangeable. The HDM100 H uses SCTE HMS protocol for modem communication. It can be used with all Teleste transponders supporting HMS protocol. It is also compatible with 3rd party transponders conforming to HMS standards. The unit is mechanically compatible with HDX002 and HDX003 installation frames.
