Cisco Systems PRP-2/R= Parameter RJ-45, Lists Ieee 802.3u physical characteristics for 100BASE-TX

Configuring Interfaces on the PRP

Table 4 lists the cabling specifications for 100-Mbps transmission over unshielded twisted-pair (UTP) cables.

Note The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.
