Dialogic® TX 4000 Series SS7 Boards

The Dialogic® TX 4000 Series SS7 Boards offer a range of form factor, throughput capacity, and signaling protocol support within the Dialogic® NaturalAccess™ Development Environment.  The TX 4000 Series architecture combines TDM connectivity and transport with the SS7 protocol layers required for a higher-level application interface.

Onboard Protocol Execution

The TX 4000 Series boards are available with MTP or MTP, ISUP, TUP, and BICC layers of the SS7 stack running on board processors.

Multiple Network Interfaces

The digital trunk interfaces of the TX 4000 Series are software-configurable to support either T1 or E1 connections. The TX 4000 and TX 4000/20 have 4 trunks, and the TX 4000C and TX 4000/20C have 8 trunks. The TX 4000C and TX 4000/20C include either a rear transition card with both digital trunk and Ethernet connectors or a rear transition card with digital trunk connectors with Ethernet connected via the CompactPCI PICMG 2.16 bus.

For network interfaces, all channels from the primary rate digital trunk interfaces can either be terminated locally on the TX 4000 Series or switched onto the H.100/H.110 bus for processing by other H.100/H.110-compliant products.

Redundancy

When deploying two boards from the TX 4000 Series in a redundant configuration, one onboard Ethernet interface is required. The interface supports a dedicated point-to-point link to provide extremely fast data transfer between the two boards. This approach avoids the need to transfer lower-level data over the host computer’s bus and can significantly improve SS7 signaling performance.
