Making External Connections to Cisco 4000 Series Routers 4-95

Network Connection Considerations

Warning Invisible laser radiation can be emitted from the aperture ports of the

single-mode ATM products when no ﬁber-optic cable is connected. Avoid exposure and do

not stare into open apertures. This product meets the Class 1 Laser Emission Requirement

from CDRH FDDI. (To see translated versions of this warning, refer to the appendix

“Translated Safety Warnings.”)

For E3 and DS-3 connections, use the 75-ohm, RG-59, coaxial cable with bayonet-style,

twist-lock (BNC) connectors and ferrite beads. (See Figure 4-55.) The E3 and DS-3 PLIMs

both use the same cable. Ensure that the transmit and receive portions of the cable are

connected to the appropriate module connector.

Connect the ATM network processor module interface cables as shown in Figure 4-56.
