Networking
All Indys shipped with AUI/10BASE-T Ethernet and ISDN as standard equipment. The Ethernet ports are half-duplex only. The 10BaseT port takes precedence over the AUI port - if the system detects a carrier on both ports, it will use the 10Base-T.
Two different manufacturers produced 100BASE-TX Ethernet cards compatible with the Indy, both of which attached to the system using the GIO32 bus. Set Engineering produced one such fast Ethernet card, based on the Texas Instruments ThunderLAN chipset, under contract with SGI. Phobos also produced models of fast Ethernet cards for the Indy (the G100 and G130).
The ISDN port provided on the Indy has no NT1. An external NT1 is required to use the ISDN port in North America.
