All LAN wiring should use Category 5 Unshielded Twisted Pair (CAT 5 UTP) cable. No single run
of LAN cable should exceed 100 meters (about 330 feet).

4.4.4.5 LAN Wiring Structure
The LAN wiring architecture used for connecting iPECS Modules to the LAN is dependent upon
several factors including:
Shared or iPECS only LAN infrastructure
External VoIP calling requirements
New or existing voice and/or data installation
Remote LAN power or local AC power for iPECS Phones
The “PC” LAN port of equipped LIP Phones can be connected to the user’s desktop using a
standard LAN cable terminated with RJ-45 LAN jacks. The LAN jack is wired to an Ethernet switch,
which has access to the LIK-MFIM50A/B, other iPECS Modules and LIP Phones. This
connection can be through a connection to the same switch or by an indirect connection through
multiple switches.
