Automatic Meter Reading Unit
-
Signals & Systems India Private Limited
SANDS make of AMR Modem SAM-1101 is a smart electricity meter reading device that can be connected to any make of electronic energy meter by means of optical/ RS232 port, which is compliant to DLMS – IEC 62056-21 standard. The electricity meters measuring energy consumption can be located in either consumer premises or in distribution transformers. The modem draws its power from the meter terminal block and connects to the communication port of the meter. Thus this add-on energy meter reading system is non-intrusive and can be retrofitted easily to any meter. The Electricity Meter Reading device uses GSM/GPRS communication technology and has built-in intelligence to talk to the DLMS meter. AMR system is compatible with 4G network to push the power consumption-billing data, load survey data, and event data to a cloud-based server, with fallback options to 3G & 2G.

Proactive Downstream Spectrum Analysis
SpectraVizion
-
SpectraVizion is an innovative, software-based diagnostics tool that leverages new advancements in remote spectrum capture, allowing cable operators to address downstream spectrum impairments proactively, before subscribers call in with service complaints. “Troubleshooting downstream spectrum issues has always been a reactive process for cable operators,” said Arthur Skinner, Vice President of Worldwide Sales for ZCorum. “Often they’re not aware they have an issue until a customer calls, and that’s when they then send a technician to the home with a hand-held meter to start a search for the problem.” SpectraVizion takes the guesswork out of problem identification and location by presenting on a simple dashboard a list of devices that are experiencing common downstream issues like Standing Waves, FM Noise, Suck-outs, Roll-off and Tilt. The tool leverages the spectrum data available from cable modems and set-top boxes that support full band capture, and advanced detection algorithms automatically identify devices experiencing downstream impairments. The operator can click on any device in the list to view a capture of the full spectrum from that day, or up to 30 days in the past.
