Cisco 585 LRE CPE Device
The CISCO585-LRE is a four-port CPE device for the
LRE solution. The Cisco 585 CPE and the current 575
CPE are fully interoperablewith the 2924-LRE-XL and
2912-LRE-XL switches. The Cisco 585 CPE shares the
same basic form factor as the current 575 CPE and has
four Fast Ethernet ports allowing customers to connect
multipledevicessimultaneously.TheCisco585CPEalso
has two RJ-11 connectors: one for ananalog phoneand
one for the LRE link (same as the 575 LRE). A section
of the top of the Cisco 585 CPE is indented to allow
customers to place customized labels, and themounting
templates on both the Cisco 585 CPE and 575 CPE are
identical allowing customers to easily replace existing
575 CPEs mounted under desks with Cisco 585 CPEs.
The Cisco 585 is targeted towards customers who
intend to deliver converged voice, video, and data
services to several devices such as computers, set-top
boxes, IP phones, wireless access points, and so on.
In order to support converged service such as
video-on-demand, the Cisco 585 CPE supports
802.1p QoS with two priority queues allowing voice
and video traffic to be prioritized over normal data
traffic. The speed of the four Fast Ethernet ports is set
to auto-negotiate, and the duplex is fixed at half.
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 copperwiring as LRE traffic. The
Cisco LRE 48 POTS Splitter enables the coexistence of
LRE and POTS on the same telephone line. 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.

Long-Reach Ethernet Technology
Long-Reach Ethernet provides an extensionto theIEEE
802.3-compliant Ethernet standard network. LRE
extends Ethernet over single-pair wiring at distances of
up to 5,000 feet. Cisco LRE technology combines
simple and standards-based LAN connectivity and
extensionoverexistingtelephonewiring,whileboasting
several competitive advantages. The Cisco LRE
technology provides a point-to-point link that can
deliver half- or full-duplex Ethernetat upto a15-Mbps
data rate. Cisco LRE technology supports transmission
of POTS, PBX, or ISDN signaling simultaneously with
data over the standard telephone-grade wire
infrastructure, and can be provisioned in the same wire
bundle as ADSL.
