A Cisco LRE CPE device, hereafter referred to as the CPE, is based on very-high-data-rate digital subscriber line (VDSL) technology. The CPE connects a computer or laptop to a Catalyst LRE switch at distances of up to 4921 feet (1500 meters) by using LRE technology over ordinary telephone lines.

Note A CPE connects a computer or LAN to an LRE switch that transmits a high-speed signal over a telephone data connection. A Cisco LRE CPE converts a VDSL-based signal on the telephone line to an Ethernet signal to the computer.

The Cisco 575 LRE CPE, Cisco 576 LRE 997 CPE, and the Cisco 585 LRE CPE have these features:

• IEEE 802.3 10BASE-T compliance
• On the 575 LRE CPE and 576 LRE 997 CPE, one autonegotiating 10/100BASE-T Ethernet port
• On the 585 LRE CPE, four autonegotiating 10/100BASE-T Ethernet ports
• Status LEDs showing Ethernet activity and LRE link status
• Data rates of up to 15 Mbps at distances of up to 4921 feet (1500 meters)

Note Data rates are reduced for longer distances. Data rates are configured through a Catalyst LRE switch. Refer to the switch hardware installation guide and the switch software configuration guide for your switch model for more information.

• An internal splitter that allows regular telephone services, such as voice or Integrated Services Digital Network (ISDN), to travel on the same lines as LRE traffic.

Certain Cisco LRE CPE devices are not supported by certain Catalyst 2950 LRE switches. the table, Yes means that the CPE is supported by the switch; No means that the CPE is not supported by the switch.
