Cisco LRE (Long Range Ethernet Extenders) 

Long Range Ethernet Extenders (LREs) use ordinary telephone lines or similar wiring to extend ethernet connections toThe Cisco575-LRE - 575 long range ethernet extender with 1 port (with power) physically distant locations. In general, an LRE switch is used on one end (like the Cisco 2912-LRE, 2924-LRE or 2950-LRE) and a CPE LRE (terminating LRE device) at the other end. The terminating device changes the signal back to ethernet, and one or more ordinary ethernet cables can be plugged into the CPE to connect a computer or other device to the network. These are the single-port Cisco575-LRE or Cisco576-LRE and the four-port Cisco585-LRE. All these units can be used as free-standing long range ethernet extenders or, for additional functonality, with a Cisco LRE switch. The 575 and 585 are optimized for use with the WS-C29XX LRE switch series, and the 576 is optimized for use with the WS-C2950 LRE switch series.

Cisco has discontinued these popular and widely used ethernet extenders. ISPTrader continues to stock and distribute 575, 576s and 585s - and at present is the only company in the U.S. still to do so as part of its regular catalog. Nevertheless, be sure to check with us regarding availability prior to placing your order.  

575-compatible LRE CPE: ISPTrader also stocks a 575-compatible LRE CPE device which has been tested and that works well in place of the Cisco 575. The 575-compatible's main difference with the Cisco 575 is that the compatible device is configured directly, rather than through the LRE Switch, and it is not optimized for use with the Cisco 2900 LRE switch series. However, it is available in quantity and is economical. To order, call us at 216-896-9967 or email us for a Click for an email quote request, or call 216-896-9967., or check our
