The PoLRE switch is a Power over Long Reach Ethernet switch. Unlike traditional Ethernet switches, the
PoLRE switch has a reach of up to 1200 feet (365 meters) and is capable of delivering power and signaling
over a single pair CAT3 cable. A Phylink adapter is installed at each IP endpoint, carrying the power and
signaling to the connected IEEE 802.3af compliant end devices.
The default PoLRE configuration supports IP phones and provides a plug and play solution for replacing a
legacy voice network using the existing network cabling plan. Up to 48 IP phones can be powered from a
single PoLRE switch.
The PoLRE switch is a 1U, 19", rackmount 24/48-port Power over Ethernet (PoE) switch. Its upstream
ports connect to the IP PBX, router or data switch over a GbE copper connection. Unlike the typical PoE
switch, however, its downstream ports connect to either one or two 25-pair RJ21 connectors and run over
voice-grade CAT3 cable extending up to 1200 feet (365 meters).
This permits the use of a legacy 2-wire telephony infrastructure to carry voice, data and signals between
the upstream switch or IP PBX to all IP endpoints in the network. Phylink adapters at the IP endpoints are
like media converters that switch from the single CAT3 pair to a standard RJ45 Ethernet PoE connection
for connectivity and power to the attached IP device.
Important: Devices attached at the IP endpoints must be IEEE 802.3af compliant.
IP telephony (IPT) systems deploying the PoLRE switch provide both the robustness of traditional
telephony systems and the easy mobility of IP devices. Multiple PoLRE switches can also be daisy-chained
together to operate in Powershare mode if one switch’s power supply should fail.
