The 9F116-01 MicroLAN Module is a two port FDDI bridge/router used to connect an external FDDI network to one of the two FNB networks, FNB-1 or FNB-2, on the SmartSwitch 9000 FNB backplane. Another configuration option allows the module to bridge/route between FNB-1 and FNB-2 on the FNB backplane. The external FDDI network connects to the 9F116- 01 using a Dual Attached Station (DAS) interface on the module's front panel. The 9F116-01 is ANSI X3T9.5-compliant with two instances of Station Management (SMT), two instances of MAC, and four instances of PHY and PMD (two per interface).
