HDM100 MANAGEMENT MODEM HDM100 is a management modem in HDO mechanics. It communicates with HFC network transponders via its RF modem, maintains a list of transponder statuses, manages the data link and provides 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. HDM100 T supports CATVisor protocol and can be used with all Teleste transponders equipped with CATVisor software. HDM100 H supports HMS protocol and can be used with all Teleste transponders equipped with HMS software, and also with 3rd party transponders conforming to HMS standards. Features − − − − − − − − −
