ISUP PSF Software

The Protocol-Specific Function for ISDN User Part (PSF – ISUP) adds the Fault-Tolerant/High-Availability (FT/HA) functionality to the ISUP software, enabling it to execute in an active/standby architecture for High Availability systems.

PSF – ISUP (FT/HA) updates the ISUP state information from the active side to the standby side so that, in case of failure, the standby can assume operations with minimal or no disruption to the system. PSF – ISUP will help in providing distribution capabilities to the ISUP software.

The PSF – ISUP software can be combined with the portable ISUP software to operate the ISUP software in these environments:

  • Pure FT/HA systems
  • Pure Distributed systems: The ISUP software is not Distributed, but the PSF – ISUP software is compatible with the DFT/HA architecture.
  • Distributed FT/HA systems: The ISUP software is not Distributed, but the PSF – ISUP software is compatible with the DFT/HA architecture.

Trillium PSF – ISUP enables telecom equipment manufacturers of soft switches, signaling gateways, signal transfer points, service control points, media gateway controllers or other products to:

  • Accelerate time to market
  • Reduce development costs
  • Reduce project risk of internally developed ISUP applications

Product deliverables consist of C source software, documentation, training, a warranty and technical support.
