Note Traffic from multiple ATM interfaces could exceed the available bandwidth in the router,
causing packets to be dropped. Therefore the Cisco 4500-M and Cisco 4700 routers currently
support one ATM module.
ATM Cabling
For single- or multi-mode SONET connections, connect the fiber cable to the SC-style receptacle on
the module front panel. The SONET SC-duplex connector is shipped with a dust plug. Remove the
plug by pulling on the plug as you squeeze the sides of the connector.
