Broadband testing platform for use in central offices, remote nodes, co-location sites, and next
generation access nodes. Accurate fast, testing for reactive or preventive maintenance and service assurance for adsl, adsl2+, carrier ethernet, and iptv services.

Broadband test platform for use in today´s broadband accss network that performs complete
electrical tests and broadband frequency sweeps for service assrance pre-qualification.
With our remote access software can be programmed to perform automated preventive testing
capabilities to repair. The siplex pro broadband test platform is the most flexible and
accurate test platform on the market today.

SIPLEX PRO EXTENDED TESTS.

Prequalification for ADSL, ADSL2, ADSL2+ and SHDSL services, from a single end. This test allows to estimate the velocity of a pair to support each service individually, giving the UP/DOWN-STREAM velocity projected in this pair, from 4,3 khz to the respective bandwidth, showing the following information for each test:

 
bulet Diverse norms configurable by the user
bulet It measures attenuation in each bandwidth
bulet It measures background noise in each bandwidth
bulet It reports the bits by carrier.
bulet RMS Value of the background noise.
bulet Detection of possible noise spectrum.
bulet Distance of the pair.
bulet UPSTREAM and DOWNSTREAM velocity.

The tests in broadband will depend on the central and network protections.
