Cisco Long Reach Ethernet Solution
Cisco 575 and 585 LRE CPE Devices
Each LRE port is terminated in the room with either the Cisco 575 or 585 LRE Customer
Premise Equipment (CPE) devices. These compact devices bridge LRE and Ethernet. The
575 CPE has one RJ-45 Ethernet connection and two RJ-11 connectors—one for the wall
and one for a telephone. The 585 CPE has four RJ-45 switched Ethernet connections and
two RJ-11 connectors and supports 802.1p QoS so that voice and video traffic are prioritized
over normal data traffic. Both the Cisco 575 and 585 LRE CPE device can be mounted on
or under a desk, or on a wall. They ship with a mount lock-in mechanism and clip-on
Ethernet cable guard to discourage theft. It supports voice (Plain Old Telephone
Service—POTS) traffic-including ISDN or digital phones-that coexists over the same LRE
line by splitting LRE and POTS traffic at the CPE device.
Cisco LRE 48 POTS Splitter
The Cisco LRE 48 POTS Splitter is a high-density, low-cost device that is ideal for building
deployments where the PBX system is on-site and POTS traffic must coexist over the same
copper wiring as LRE traffic. Unlike “splitterless” building broadband network solutions,
the Cisco LRE 48 POTS Splitter ships as a separate, compact form factor to ensure that
POTS service is separate, and never compromised by LRE switch reconfigurations or
downtime.
The Cisco LRE 48 POTS Splitter supports 48 ports in a 1RU form factor. Each splitter has
six RJ-21 connectors-two each for connectivity to the patch panel, the LRE switch(es), and
the on-site PBX system.
Key Features
• Performance—Delivers 2-15 Mbps symmetric over existing category 1/2/3 wiring at
distances up to 5000 feet. Rate Selection feature automates the process of selecting a
data rate for a line for ease of installation and increased robustness.
• Powerful Gigabit Ethernet uplink options—1000BaseT and SFP ports
• Superior control through intelligent services—advanced quality of service and security
based on Layer 2 through Layer 4 parameters.
• Multicast support—Multicast VLAN Registration (MVR) and IGMPv3 Snooping.
• Enhanced Cisco IOS Services
• Network Management—Cisco Switch Clustering technology and the advanced,
Web-based Cisco Cluster Management Suite (CMS) software deliver easy-to-use
configuration and ongoing monitoring and management of up to 16 switches. This
software is embedded in the switches and delivers remote management of clustered
switches and connected CPE devices through a single IP address
