The TX 4000 board provides:
• PCI bus connectivity
Each board is designed to reside in a single PCI bus slot. Each board contains a
universal (5.0 V or 3.3 V signaling) PCI bus interface that is compliant with the
PCI Local Bus Specification, Revision 2.2. The PCI interface is a 33/66 MHz, 32-
bit master/target device.
• H.100 bus connectivity
The TX 4000 board fully supports the H.100 bus specification. The H.100 bus
enables boards to share data and signaling information with other boards on the
H.100 bus. For example, you can connect two or more TX 4000 boards for
applications that perform trunk-to-trunk switching. In addition, you can use
H.100 compatible products from other manufacturers with the TX 4000 board.
The H.100 interface supports a full mode stream configuration on the H.100 bus
with 32 streams at 8 MHz each. Each stream provides 128 timeslots for a total
of 4096 timeslots.
