For installations where telephone services will be routed to a PBX switch, you can
install a Cisco LRE POTS Splitter (PS-1M-LRE-48). For more information about
this POTS splitter, refer to the Installation and Warranty Notes for the Cisco
LRE 48 POTS Splitter.
If the building does not use a PBX and telephone services are sent directly to an
outside PSTN, you must provide a homologated POTS splitter. For more
information about homologated POTS splitters, contact your Cisco sales
representative.
