To install and use the TX 4000C board, your system must have the following components:
An available CompactPCI bus slot.
At least 8 MB of memory (excluding operating system requirements).
Natural Access software development environment.
Dialogic™ NaturalAccess™ Signaling Software.
A CompactPCI chassis with an H.110 compliant backplane.
An uninterruptible power supply (UPS). Although a UPS is not strictly required, it is strongly recommended for increased system reliability.
Cables to connect the board interfaces to T1 or E1 lines.
A crossover Ethernet cable if you are connecting two TX boards for redundancy support using the external Ethernet connectors on a rear I/O transition board.
