4.12. Fibre Distributed Data Interface (FDDI) Controllers (DCCG084, DCCG102, DCCG103,
DCCG123, DCCG124 and DCCG125)
The FDDI UTP Single Ring adapter (DCCG125) has been discontinued on the T610 and PL600T as of
31/08/2001.
DCCG123 and DCCG124 Discontinued: 30/04/2003.
The Fibre Distributed Data Interface FDDI is designed to allow an Escala system to connect to:
Multi-mode fiber Single-Attach Station (SAS) or Dual-Attach Station (DAS)
UTP (Unshielded Twisted Pair) Single Attach Station (SAS)
A FDDI LAN can be up to 100 km (62 miles) long and can include up to 500 system units. There can
be up to:
2 km (1.24 miles) between system units or concentrators when using multi-mode fiber
100 meters between system units or concentrators when using UTP.
Remote IPL is not supported via FDDI devices.
