Installing the H.100 Bus Cable
To support OneBox, Aastra sells PCI linecards that exchange data with one another through a
H.100 bus-compliant resource bus. The H.100 bus standard specifies a hardware design that
supports signals from several earlier resource bus specifications including CTbus, SCbus,
MVIP, and others.
Each Dialogic PCI linecard is equipped with an H.100 bus connector to which an H.100 bus
cable attaches. Because the OneBox software is designed to work without terminated resource
buses, it is not necessary to add a terminator pack of any sort to either end of the H.100 bus
cable or to change the termination settings on any H.100 bus board in the system.
NOTE
The terms CT Bus and H.100 are often encountered together. H.100 refers to the specific
variant of the CT Bus specification used in PCI linecards.
If you have more than one PCI card installed, you must cable the cards together with an H.100
bus cable.
IMPORTANT
Do not terminate the board at either end of the H.100 bus cable.
1. Plug the first (end) connector on the H.100 bus cable to the H.100 bus edge connector
on the top edge of the first PCI card.
2. The connectors are designed to fit together one way only. If the connector does not seat
fully on the card, turn the cable around and try again. When attached correctly, the
colored stripe on the cable faces the rear bracket. (The stripe must be adjacent to pin 1
on the card connector.)
3. Plug the last (opposite end) connector on the H.100 bus cable to the H.100 bus
connector on the last PCI card installed in the platform.
4. Plug a connector on the H.100 bus cable to the H.100 bus connector on each remaining
intermediary PCI card installed in the platform.
5. Tuck any extra connectors or loose ribbon cable down into the chassis so that it does
not snag when you replace the platform cover.
6. Replace the cover on the platform and plug in the power cord.
