Confidential telecommunications equipment manufacturer
Designed software to support a Voice Option Module.
As part of its ongoing support for this customer, Impact ES–Rhode Island provided sustaining support for their custom DSP voice/fax processing firmware, which was executed on T.I. C549 DSPs.
To increase voice channel density and reduce cost per voice port for their digital interfaces, the client was interested in outsourcing the porting of this firmware system to the T.I. C5441 DSP, a four-core device. The client also aimed to minimize their internal resource involvement in the project. The task was made more difficult by Texas Instruments’ withdrawal of software support for the original base firmware, which had previously been customized by the company.
Impact ES–Rhode Island provided the following services:
Voice protocol software/DSP firmware architectural review
Voice DSP firmware port (C5441) and enhancement
Host processor digital voice driver enhancement to support C5441 host port architecture
Performance tuning of the resulting system
Digital T1/E1 voice software integration testing
Acceptance testing support
