10/100 Ethernet Card

Ethernet Card

More than one card may be present in a system. RJ-45 connection to standard Cat-5 UTP network cable. Systems with one Ethernet card support both Host and Comms (DIS/HLA) interface via a single card. If the system has two Ethernet cards, one is the "Dedicated Host" interface, the other is the "Dedicated Comms" interface. See AN31b: DACS/Telestra Chassis & Slot Configurations for more information.


Dual 10/100 Ethernet Card

Dual Ethernet Card

1U Telestra systems only. Card may be supported for DACS systems 2001. RJ-45 connection to standard Cat-5 UTP network cable.

See AN31b: DACS/Telestra Chassis & Slot Configurations for Ethernet card assignments.


Time Division Multiplex Digital Signal Processor (TDM DSP)

TDM DSP Card

Foundation for "TDM Ring" which is a loop that connects one or more Remote Interface Units (RIUs) to the DACS system. RJ-45 connection to standard Cat-5 UTP network cable. See the Remote Interface Unit Technical Guide for details regarding proper TDM Ring connection.
