Route Processor Cables

As you consider system cabling, see Table 4-1to determine the types of cables required to connect to ports on the route processor (RP).

Table 4-1 Route Processor Cables

RP Port	Required Cable Type
Ethernet management	Shielded twisted-pair (STP) cable (Category 5 or better). Required
	for enhanced immunity to external electromagnetic disturbance
	levels of 10 V/m and 10 Vrms.
Alarm	Shielded cable. Required for EMC compliance.

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, and 10-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. Cisco can assist you in planning custom cables.
