Performance and Cost Optimization
Ditech’s QVP enables carriers to optimize performance and reduce the cost of their voice networks by
eliminating low-density echo cancellation equipment. Ditech’s versatile platform supports a wide range
of applications. Ditech’s VQA software suite for the QVP T1 offers a range of application-specific packages
to meet the needs of any network.
Future-Proof Platform
As voice technologies and central office requirements change, the QVP can be reconfigured, upgraded while in
service, or redeployed. Simplified remote management eliminates the time and expense of performing costly onsite
configuration, maintenance, and upgrades. The QVP is backed by a dedicated Ditech support team providing 24x7
service.
Enterprise Solution
When installed in the 4sa Enterprise shelf, the QVP T1 provides a cost-effective solution for Enterprise or
Remote Office applications, providing voice processing for between 1 and 4 T1s in a compact, tabletop or rack-mountable,
AC- or DC-powerable chassis with RJ-48 or wire-wrap connectors.
Carrier Solution
When installed in the 80sa Carrier shelf, the QVP T1 provides a high-density narrowband echo cancellation solution that
easily scales from 1 to 80 T1s per 19″ rack-mount shelf assembly. The 80sa Carrier shelf is available with either
wire-wrap or Amphenol connector options and is engineered with dual redundant –48 VDC power and forced-air cooling
for central office deployments. Up to 6 Carrier shelves can fit in a 7′ rack, for up to 480 T1s per rack.
