6-port DS3 Frame/IP IOP Module
The 6-port DS3 Frame/IP module enables the CBX 500 to operate as a multiservice
switch by providing IP routing for cell-based IP traffic, Frame Relay switching, and
Frame Relay-to-ATM interworking. In addition, the module works with IP Services to
provide routing for the entire CBX 500 switch through a local IP forwarding engine
on the module.
The DS3 Frame/IP module enables the CBX 500 to accept Frame Relay traffic at
44.736 Mbps at each port and provides line-speed packets at 128-byte frames.
The CBX 500 16-slot modular architecture can support up to 84 DS3 Frame Relay
ports per switch.
You can configure the following trunk interfaces on the 6-port DS3 Frame/IP module:
• Frame Relay UNI
• Frame Relay NNI
•IP
• ATM FUNI
• Direct or OPTimum trunk
