TELECOM TEST SYSTEM FOR TIA/EIA-IS-968 (FCC PART68) TESTING

Rack mountable (19 inch) system designed to perform testing according to Telecommunication Industry Association (TIA) / Electronic Industry Alliance (EIA) standard TIA/EIA-IS-968 Technical requirements for Connection of Terminal Equipment To the Telephone Network (formerly FCC Part 68. Go to following link to read more about it ( Administrative Council for Terminal Attachments ) and and Industry Canada CS03. This system contains most of the specialized circuitry needed to perform testing on analog modems and analog telephones (excludes FCC 68.317- Hearing aid comparability volume control for Analog Telephones). Other "General purpose" or third party equipment may be needed to perform some of the tests.

Surge Generator (SG-168)

The Model SG-168 Surge Generator was designed for applying high voltage surges to equipment connected to the telephone network.  The SG-168 Surge Generator is capable of performing telephone line surge type A and type B per TIA/EIA-IS-968 and Industry Canada CS03 requirement.   

Longitudinal Signal Power and Balance (LB-168)

The LB-168 is capable of analyzing Longitudinal Signal Power and Longitudinal Balance of telephone interface devices. Longitudinal Signal Power measurement is required because, telephone lines cover a great distance, telephone networks might use complex multiplexing schemes when when communicating from one central office to another and to limit cross talk between lines. Please see application table below.

Impedance Test Set (IS-268)

The Impedance test set model IS-268 is designed to analyze AC and DC on hook impedance of a telephone interface device. The AC and DC on-hook impedance during ringing tests were designed to protect the telephone network from excessive current flow while on-hook.

Ringer Set (RS-368)

The Ringer set model RS-368 is capable of supplying the ringer voltage for the On Hook impedance and billing protection testing.

The LS-468 is a two-wire loop simulator. It is designed to simulate the full range of voltage, current and AC impedance parameters normally encountered when connected to the telephone network.

Digital Service Longitudinal Balance (DB-568)

DB-568 is designed to analyze longitudinal balance of terminal telephone equipment that use digital service.

Loop Simulator for 26 AWG (LS-668)

The model LS-468 Loop Simulator 26 AWG Cable was constructed to meet the requirement of FCC 68.317 paragraph (b) for is for testing analog telephones for Receive Objective Loudness Rating (ROLR).
