Hotel Network Configuration
Figure 1-4 shows Catalyst 2950ST-8 LRE and 2950ST-24 LRE switches in a hotel network environment
with approximately 200 rooms. This network includes a PBX switchboard, a router, and high-speed
servers.
Connected to the telephone line in each hotel room is an LRE CPE device, such as a Cisco LRE CPE
device. The LRE CPE device provides:
• Two RJ-11 ports, one for connecting to the telephone jack on the wall and one for connecting to a
POTS telephone.
• One or more RJ-45 Ethernet ports for connecting to devices such as a customer’s laptop, the room
IP phone, the television set-top box, or a room environmental control device. A Cisco 575 LRE CPE
provides one Ethernet connection; a Cisco 585 LRE CPE provides four.
When connected to the CPE device, the Ethernet devices and room telephone share the same telephone
line.
