Cheetah
CMD-N-Motorola Embedded Node Transponder

Tollgrade’s Cheetah DOCSIS-based transponders enable cable operators to proactively monitor and control their Fiber Nodes using existing DOCSIS infrastructure. The transponder utilizes the standards adopted by the SCTE-HMS subcommittee for fiber node monitoring and provides easy access to information and control through standard SNMP mibs. The transponder also features the ability to conduct HSIA and VoIP testing through embedded software.

Features include: Ethernet port, optical tamper switch, standard cable modem LEDs, web page access, eMTA emulation and embedded VoIP testing. The transponder continuously monitors and reports out of tolerance conditions via SNMP traps. All alarming thresholds are user-definable.
