Configuring Interfaces on the PRP
To comply with Telcordia GR-1089 NEBS standard for electromagnetic
Note
compatibility and safety, connect all console, auxiliary, Ethernet, and
BITS (PRP2) interfaces only to intrabuilding or nonexposed wiring or cabling.
The intrabuilding cable must be shielded and the shield must be grounded at both
ends.
Figure 10 shows a PRP RJ-45 receptacle and cable connectors. The RJ-45
connection does not require an external transceiver. The RJ-45 connection
requires Category 5 unshielded twisted-pair (UTP) cables, which are not available
from Cisco Systems, but are available from commercial cable vendors. Table 3
lists the pinout for the RJ-45 receptacle.

extra-low voltage (SELV) circuits. SELV circuits should only be connected to
other SELV circuits. Because the BRI circuits are treated like
telephone-network voltage, avoid connecting the SELV circuit to the telephone
network voltage (TNV) circuits.
