Route Processor Cables
As you consider system cabling, see Table 4-1 to determine the types of cables required to connect to
ports on the route processor (RP).
PLIM Interface Cables
You must provide the PLIM interface cables. Because the type and number of interfaces can vary, plan
these cable runs prior to the installation. When planning the cable runs, consider the following:
• Number and type of interface connections (OC-48/STM-16, OC-192/STM-64, OC-768/STM-256,
10-Gigabit Ethernet, and 100-Gigabit Ethernet)
• Termination at the other end of the cables (such as patch panel or optical transport equipment)
• Proper length and termination of cables
Custom Cables
The installation site may require custom cables designed for the facilities. We can assist you in planning
custom cables.
