DDS QUICK TESTER
The DDS
QUICK TESTER is a 0-64 kilobit DDS (digital data
service) quick continuity tester. It provides for an overall test
of all wiring on the DDS circuit from the telephone company's
channel bank to the RJ48S jack where the CSU / DSU is attached.
This allows for a rapid test of the complete loop from the OCU to
the demarcation point at the customer's site.
Telephone Company technicians and independent technicians as well agree that they have found the unit to be a quick method of determining the condition of the 4 wire facilities that 56k & 64K DDS circuits use.
The unit is very user friendly. It detects if the facility wiring has the proper continuity and then informs the technician with 4 green LED's as a pass (or all's ok) condition. It also gives 2 red if the circuit has become flipped. If there happens to be a split pair the unit will inform the technician that there is a major problem by illuminating 1 red & 1 green. The DDS QUICK TESTER will also check your 8 wire straight cord independent of the circuit. Use the link below to contact us and we will be glad to assist you with the DDS QUICK TESTER.
