COCX-F3 Line Modules and Associated I/O Modules

ERX-7xx models, ERX-14xx models, and the ERX-310 router support the COCX-F3 line modules and associated I/O modules.

ERX-14xx models support up to twelve COCX-F3 line modules and twelve corresponding I/O modules, ERX-7xx models support up to five of these line modules and five corresponding I/O modules, and the ERX-310 router supports up to two of these line modules and two corresponding I/O modules. There are twelve physical T3/E3 (DS3) ports per I/O module. Each port uses two SMB connectors: one for the transmit (TX) connection and one for the receive (RX) connection.

COCX-F3 line modules and associated I/O modules support the following:

• Clocking
• Redundancy
• Frame Relay logical interface support
• Unique IP interface support for each PPP or Frame Relay PVC interface
• HDLC
• Fractional T3 (T3 only)
• Line speeds of 45 Mbps (T3) and 34 Mbps (E3)
