Legacy 2- and 4-Wire Copper Circuit - Seamless 4G/LTE Only/XLTE w/ 3G Cellular Conversion
The Problem
Older water supply systems with equipment in the field connected by analog modems to Plain Old Telephone Service (POTS) copper lines are experiencing service delays, dependability issues, and increasing Operational Expenditures (OPEX).
Due to the phase out of copper wire line based circuits and limited data throughput, coupled with longer outage times for repair of down circuits, waste and water companies must move to new TCP/IP enabled transport, without having to replace their embedded equipment or change their back office procedure. Placement of legacy water equipment can be found from several floors below ground in wet well locations, to remote reservoirs, pump stations and other systems points all with copper plant that is inaccessible, and deteriorating.
Faced with new hurdles, from gaining reliable access to their older water system equipment, Capital Expenditure (CAPEX) shortages, and non-TCP/IP solutions, waste and water companies must move their existing infrastructure to a cost effective, secure, and dependable digital IP backhaul without disrupting the existing equipment and operations or without an expensive equipment overhaul.
The Solution
The solution is the Encore Networks industrially hardened BANDIT-2 C2C™ copper to cellular router. The BANDIT-2 C2C™ provides IP, VPN, Encryption, Firewall, Ethernet connectivity, conversion of legacy analog data via serial protocol such as Modbus and DF1, and an end point facing Central Office analog modem transported via an embedded 4G/LTE Only/XLTE w/3G Fallback cell modem on either a private or public cellular IP network. The Encore Networks solution is easy to implement, and eliminates the OPEX costs of the 2 and 4-wire copper lines while preserving CAPEX. The switch from a 2-wire copper paired POTS line to a cellular data connection is simply done by unplugging the analog modem connected equipment from the copper line jack, RJ-11/demarc, and terminating it on the BANDIT-2 C2C™ for traditional analog dial out/in modem connections. Bypassing older 4-wire Data Service Units (DSU) is simply done by unplugging the serial data cable from the PLC/CPE and plugging directly into the serial port of the BANDIT-2 C2C™. In both cases the BANDIT-2 C2C™ handles the analog modem/serial data communications and conversion of the data for transmission over a private or public 4G or 3G cellular network using a secure VPN with IPSec encryption to ensure end-to-end security. The BANDIT-2 C2C™, using its dual antennas for signal diversification and the ability to be installed over 1500’ away from the existing 2-wire analog modem with twisted copper pair, makes for an easy installation in the most difficult areas. The BANDIT-2 C2C™ is capable of delivering IP/Ethernet based services at a fraction of the cost with its configurable Ethernet port addressing future TCP/IP based services at the site. Increased bandwidth allows for additional equipment such as High Definition security video and newer intelligent waste and water infrastructure equipment for M2M and SCADA communications.
