Hardened DOCSIS Gateways


The Lindsay DOCSISLoop is a hardened cable modem designed to maintain reliability in the harsh HFC environment and minimize the cost of status monitoring. The outdoor DOCSISLoop uses a standards based DOCSIS cable modem that is wholly under the control of the MSO through the CMTS. It can be used in conjunction with SNMP monitoring systems to evaluate cable plant line conditions. Important line quality indications such as Signal Strength, Signal to Noise Ratio, Bit error rate and much more depending on your operating system. This device is quick and easy to install connected to a power passing multi-tap, directional coupler or as a network termination. The integrated HFC interface includes 6Kv surge with stand, upstream and downstream modem sweet spot level controls and -20dB test points.
