Connect the other end of the cable to the patch panel or POTS splitter.
Step 3
Each LRE port status LED turns on when it establishes a link with a Cisco
575 LRE CPE. For more information about the LRE link between the switch LRE
port and the CPE, as well as information about the configuration and management
of CPE devices, refer to the Catalyst 2900 Series XL and Catalyst 3500 Series XL
Software Configuration Guide.
For more information about the Cisco 575 LRE CPE device, refer to the
Cisco 575 LRE CPE Hardware Installation Guide.
If telephone services, such as voice or ISDN, use the same cabling as LRE traffic,
the LRE port must be connected to the patch panel through a basic telephone
service, also known as plain old telephone service (POTS) splitter. The splitter
routes LRE data (high-frequency) and voice (low-frequency) traffic from the
telephone line to the switch and private branch exchange (PBX) switch or
public-switched telephone network (PSTN).
If the other telephone services are connected through a PBX switch, a
Cisco LRE 48 POTS Splitter can be used. The PBX routes voice traffic to private
telephone networks and the public system telephone network (PSTN). For more
information about the Cisco LRE 48 POTS Splitter (PS-1M-LRE-48), refer to the
Installation Notes for the Cisco LRE 48 POTS Splitter.
If the installation does not have a PBX, a homologated POTS splitter is required
to directly connect to the PSTN. For more information about homologated POTS
splitters, contact your Cisco sales representative.
Note If a connection to a phone network is not required at all, a splitter is not
needed, and the switch can connect directly to the patch panel.
