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
• Quality of Service—802.1p QoS support provides high and low priority queuing
on a per-port basis. Layer 3 QoS support-including DiffServe and
application-based queuing—when aggregated by a Layer 3 switch.
• Scalability—Up to 15-Mbps symmetric performance over single-pair wiring; Fast
EtherChannel port aggregation.
• Security—802.1Q port-based virtual local-area network (VLAN) support; Cisco
private VLAN access, assuring port security without requiring a VLAN per port;
Access control list (ACL) security when a LRE switch is aggregated by a Cisco
Layer 3 10/100 Ethernet switch.
• 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.
