Splitter.
Cisco Long-Reach Ethernet (LRE) products are designed to share lines with
analog, Integrated Services Digital Network (ISDN), and digital private branch
exchange (PBX) switch telephones that use the 0 to 700 kHz frequency range.
Digital telephones connected to digital PBX switches that use frequencies above
700 kHz do not work when sharing a line with LRE signals. Due to the proprietary
nature of digital PBX switches, some digital PBX switch services use frequencies
above 700 kHz. [CSCdu73260]
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.
If a connection to a telephone network is not required, a splitter is not needed, and
the switch can connect directly to the patch panel.
The module slots (see
modules. Each module port is internally switched to other switch ports and is
managed through the switch management interfaces.
Table 1-1 lists the modules that the module slots support.
