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 E1 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 E1 provides a cost-effective solution for
Enterprise or Remote Office applications, providing
voice processing for between 1 and 4 E1s in
a compact, tabletop or rack-mountable, AC- or
DC-powerable chassis with RJ-48, wire-wrap, or
BNC connectors.
Carrier Solution
When installed in the 80sa Carrier shelf, the QVP
E1 provides a high-density narrowband echo
cancellation solution that easily scales from 1
to 80 E1s per rack-mount shelf assembly. The
80sa Carrier shelf is available with either BNC or
wire-wrap 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 2200 mm rack, for up to
480 E1s per rack.
