About the TX 2000/TX 3000

The TX 2000/TX 3000 boards provide a powerful hardware platform for a variety of communications and networking applications.
The modular design is based on an intelligent Communication Processor (CP) which plugs into a single ISA bus slot. The CP cooperates with the ISA bus host processor (IBM PC/AT) to form a distributed communications application platform. Interface adapters are connected directly to the multiprotocol processor for high throughput without intervention from the computer's processor.
The CP features a high-performance 68360 quad-integrated communications controller with a 16-bit ISA bus interface. Plug-in adapter boards are available for Ethernet connectivity (10 Base-T), Dual T1, Dual E1, sub-360 processing upgrades, and a V.35 serial interface.
The TX 2000/TX 3000 board CP is software programmable for a wide variety of applications. Networking software packages include Signaling System 7 and Fusion for Telephony over IP. Interfaces are available for Windows NT, UnixWare 2.x, and Intel Solaris to permit access to applications and protocol stacks running on the communications processor.

Figure 1 illustrates a TX 2000 board and the main components that comprise it. Figure 1. TX 2000 Board
The TX 2000 board provides: ISA bus connectivity Each board is designed to reside in a single ISA bus slot. MVIP-90 bus connectivity The TX 2000 board provides full support of the MVIP-90 telephony bus standard, which allows boards to share data and signaling information with other boards on the MVIP bus. Daughterboard support The TX 2000 board can be ordered with a Dual T1/Dual E1 daughterboard for digital trunk connectivity. A 10Base-T Ethernet daughterboard is available for Ethernet connectivity. The TX 2000 board supports the V.35 protocol via a separate daughterboard. A single sub-360 daughterboard is also available to provide additional serial communication controller resources for the TX 2000. For more information on the TX 2000 daughterboards, see Chapter 6. Variable memory configurations Each TX 2000 board comes with a 4-MB SIMM installed. The TX 2000 can support an additional 4-MB SIMM for a total of 8 MB of memory.

Single/Triple sub-360 daughterboards are also available to provide additional serial communication controller resources for the TX 3000. For more information on the TX 3000 daughterboards, see Chapter 6. Variable memory configurations Each TX 3000 board comes standard with 4 MB of SDRAM. An optional 8-MB or 32-MB DIMM may be added to the TX 3000 board for additional memory.
