Description

The CableSHARK RM™ is the next-generation CO based VF/DSL cable qualification device for measuring and evaluating the local loop for DSL deployment. The CableSHARK RM™ 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 RM™ 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 RM™ 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 RM™, 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 RM™ 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 RM™, 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 RM™ also measures noise and impulse noise using psophometric and 3 kHz flat filters.

World's first single-ended ADSL test solution

The CableSHARK RM’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 RM™ 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 RM™ supports ping testing.

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

The CableSHARK RM™ 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 RM’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.
