Description

The CableSHARK P3 includes the necessary VF and broadband measurements for qualifying and troubleshooting a local loop such as loop holding/dialling, frequency response, time domain reflectometry (TDR), longitudinal balance, load coil detection, bridge tap detection, power spectral density, resistive fault location (RFL), noise and impulse noise measurements. The CableSHARK P3 is the next-generation CO based VF/DSL cable qualification device for measuring and evaluating the local loop for DSL deployment.

The CableSHARK P3 is easy to use and features precision single end line testing (SELT) capabilities. These SELT capabilities include ADSL data rate prediction (patent pending), SHDSL data rate prediction, VF band qualification, and an powerful time domain reflectometer (TDR). The CableSHARK P3 can qualify circuit characteristics up to 6 MHz CO. CPE modem emulation, including CPE-based IP testing, verify network connectivity beyond the local loop.

View circuit quality

The CableSHARK P3 is a rack mountable unit for use by DSL service providers (PTT) in parallel with their existing DSLAM, metallic test access unit (standard or intelligent MTAU) or next-generation digital loop carrier (NGDLC). Installing the CableSHARK P3, in conjunction with a MTAU, between the MDF and the POTS splitter, gives the service provider an accurate look at the copper pair without the POTS splitter’s capacitive influence.

Qualify the local loop to carry DSL services

The CableSHARK P3 can easily qualify the local loop to carry such DSL applications as ISDN, HDSL, HDSL2, G.Lite, SHDSL, ADSL, ADSL2 and ADSL2+. This testing unit allows you to test the physical layer for line faults and restrictive wireline impairments such as bridge taps (multiple appearances), load coils, bad splices, ingress noise, impulse noise, and crosstalk from adjacent pairs in the cable bundle.

Conduct VF tests

ADSL and voice operate on the same circuit in the majority of cases. Using the CableSHARK P3, service providers can ensure that the voice circuit is electrically sound by performing VF tests such as resistance, capacitance, and isolation resistance tests on the line. The CableSHARK P3 also measures noise and impulse noise using psophometric and 3 kHz flat filters.

World's first single-ended ADSL test solution

The CableSHARK P3's single-ended ADSL data rate prediction test (patent pending) is capable of evaluating a circuit’s ability to carry ADSL bit rates from the CO. This versatile addition to the patented end-to-end ADSL data rate prediction test allows us to offer a truly single-ended test set designed to locate impairments and save users time and money.

Network verification tests beyond the CO

The CableSHARK P3 can be configured to house ADSL, SHDSL, VDSL or a combination of DSL modems that allow service providers to test above the physical layer and verify network connectivity. Utilizing PPPoE encapsulation, service providers can emulate the user experience and test the connection to the B-RAS, ensuring the customers username and password are properly configured. Beyond the RAS, the CableSHARK P3 supports ping testing.

Locate loop faults with the CableSHARK RM's best-in-Class TDR

The CableSHARK P3 comes with a fully functional and graphical Time Domain Reflectometer (TDR). The integral TDR sends out user modifiable energy pulses over the copper loop and ‘looks’ for reflections to locate loop faults. The CableSHARK P3’s TDR shows the location/length of bridge taps, changes in wire gauge, shorts, opens, load coils, and any other impairment that may exist on the line.
