Figure 3-35 Limitations Using a Cisco LRE 48 POTS Splitter with a
Catalyst 2950ST-24 LRE 997 Switch and a Cisco 576 LRE 997 CPE
Required Cables
Connecting the LRE port to a patch panel or a POTS splitter requires a
male-to-male RJ-21 cable, Category 3 or above. You can order RJ-21 cables from
your cable vendor, or you can order these cables from your Cisco sales
representative:
• CAB-5-M120M120-5= (Category 5 cable with 90-degree, male-to-male
RJ-21 connectors)
• CAB-5-M180M120-5= (Category 5 cable with 120-degree, male-to-male
RJ-21 connectors)
The screws that you need to secure the cable to the switch are shipped with the
cable. Contact your Cisco sales representative for more information.
