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.

Directional Acoustic Transponder (DAT)
The Benthos Directional Acoustic Transponder (DAT) is anextension to the Teledyne Benthos ATM-900 Series modem, which automatically estimates the azimuthal and vertical arrival angles of a message sent by a remote modem. The system is a modified ultra-short baseline (USBL) which uses a broadband component of a typical modem message to form estimates of arrival angle(s). While conventional USBL devices employ tonal signals, our appropriate processing of wide band signals provides far better combined range and arrival angle estimation, especially at low Signal to Noise Ratio (SNR). Our device offers a clear 360 degree field of view in azimuth, and an approximate vertical coverage spanning + 90º overhead to -50º below horizontal.

XDSL Testers
GAOTek offers a wide range of xDSL testers that are specifically manufactured to meet the requirement of xDSL testing, along with ADSL, ADSL2, ADSL2+, READSL, and VDSL for sale to the United States, Canada and Globally. They are mainly used by field operators for telecommunication installation, troubleshooting of xDSL network and maintenance. xDSL testers not only tests the physical structure but also evaluates whether the line is fit for xDSL service and consider the quality of service. The devices can be operated in “ATUR+PC” simulation without any external ADSL2+/VDSL2 modem or computer as they can be easily operated by digital multi-meter. These devices evaluate line quality, carry out PPPoE dial-up, suggest web page browsing to determine the connection to the ISP, and emulates a PC+ modem. These testing devices also help with PING, IP config, route and tracert tests. Moreover, these devices can also function as a computer for examining broadband IP lines or begin a PPPoE dial-up to determine IP network connection and troubleshooting a computer or modem issues.
