Nodes

† Support for the Arris SG4000 and MBN series

Nodes

† Transponder automatically detects installation in SG4000 or MBN Nodes

† Differentiate between RF problems in the HFC network and headend problems

† Control attenuators to troubleshoot RF Return

Path issues

† Control A/B switches to select redundant fiber paths

† Alarm on loss of light or degradation of fiber path

† Alarm on automatic receiver switching

† Allow analysis of network congestion via HSIA testing

Cheetah Technologies’ Cheetah DOCSISbased transponders enable cable operators toproactively 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 testing through embedded software.

Features include: Ethernet port, optical tamper switch, standard cable modem LEDs and web page access.

The transponder continuously monitors and reports out of tolerance conditions via SNMP traps. All alarming thresholds are userdefinable.

Ethernet Port

The Ethernet port provides local access to embedded web page for configuration and control.

Optical Tamper Switch

The optical tamper switch embedded in the transponder will report on the status of the node (open or closed lid).

Cable Modem LEDs

The cable modem LEDs display registration status of the transponder in the DOCSIS network.

Embedded Web Page

The embedded web page can be used to display both cable modem and HMS node data gathered from the transponder. HSIA testing is supported through the web page and can be accessed either locally via the Ethernet port or remotely via a browser application.
