HDM100 T Management modem
The HDM100 T is a management modem with CATVisor 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 T supports Teleste transponders using Teleste CATVisor protocol. The unit is mechanically compatible with HDX002 and HDX003 installation frames.
