TX 4000 board features

The Dialogic® TX 4000 PCI SS7 Network Interface board is a PCI board that provides four T1 or E1 digital trunk interfaces and two Ethernet 10/100Base-T interfaces. The TX 4000 design is based on an intelligent communication processor (CP) that plugs into a single PCI bus slot. The CP operates with the PCI bus host processor to form a distributed communications application platform.

The CP features one high-performance Motorola MPC7457 RISC microprocessor and one MPC8260 PowerQUICC II controller with a 32-bit PCI bus interface. Dialogic® NaturalAccess™ Signaling Software packages provide programming capabilities for the TX 4000 board CP.

The TX 4000 board provides:

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.

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.

Switching for the TX 4000 board offers support for the H.100 bus within the H.100 architecture. On the TX 4000 board, switch connections are allowed for a total of 256 half duplex or 128 full duplex connections between local devices and the H.100 bus. Switch connections between local devices are non-blocking.

The TX 4000 board supports two 10/100Base-T Ethernet connections. These connections provide Fast Ethernet connectivity and IPv4 support. Ethernet connectivity provides the TX 4000 board with a connection to a redundant mate TX board or to a network of other SIGTRAN devices.

Each TX 4000 board includes 128 MB of SDRAM.

The TX 4000 board supports up to four T1 or E1 connectors through two Dialogic® MD1 RJ-45 interfaces. Dialogic® NaturalAccess™ Signaling Software enables you to configure the board as either a T1 or an E1 board.
