CTC provides services to conduct electronic tests of cable systems or oversee the cable operator's performance testing process. CTC also conducts independent tests as directed by the franchising authority to ensure that the cable system is maintained in accordance with FCC and local franchise requirements. CTC prepares the results of the tests in a report form that is provided to the franchising authority.

For Montgomery County, MD and other clients, CTC uses a series of test procedures that it administers on behalf of the franchising authority to document the cable operator's compliance with the technical requirements of the franchise agreement. This work includes observing the cable operators semi-annual FCC proof-of-performance tests in order to verify that the operator's staff is competent and is conducting the tests properly. In addition to the FCC tests, CTC also conducts a subset of the required FCC tests to monitor system performance at selected sites throughout the community. These tests ensure that the entire system is maintained to a high standard throughout the year—not just on the required two occasions at a limited number of sites per the FCC's requirements.

CTC also monitors the cable operator's tests to demonstrate acceptable performance of new areas of construction in the form of activation tests. These tests ensure that the plant is operating properly before it is released for new subscriber connection, thus precluding potential problems on newly activated plant.

Other tests are conducted periodically or as needed. These tests include tests of the PEG programming origination transmission links to ensure that the PEG signals are maintained to the same standard as the other cable channels. Tests are conducted not only at the cable system headend, but also at the major hub sites on the cable system to ensure that the primary optical fiber and coaxial distribution systems are operating within the required technical parameters.

In the event that equipment is not provided by the cable operator, CTC uses its own equipment to conduct its tests. CTC's equipment includes cable depth measuring equipment, Stealth signal level meters, spectrum analyzers, and audio processing equipment. CTC has also developed its own software for test analysis for its clients. CTC's proprietary software interprets electronic measurements in order for CTC to report test results to its clients. Technically qualified personnel are on-site or available immediately to conduct tests as required and are familiar with the technical requirements and operation of all test equipment.

CTC staff are also available to immediately respond to subscriber complaints regarding signal quality, and if necessary, perform electronic tests and record measurements using CTC's own test and analysis equipment. As with CTC's reporting of its inspection work, CTC also maintains a test results database and provides detailed reports of all results of its electronic testing findings. These tests frequently go somewhat beyond the required FCC performance measurements, because the FCC standards set minimal performance levels only. CTC has effectively used this process to obtain cable operator cooperation in providing systems improvements. The results of these tests are expressed in records of actual measurements, comparative statistics over time, and graphical representation of test results. As requirements change over time, CTC recommends revisions to test procedures or standards to meet changing requirements. Most recently, CTC is preparing the test procedures for Montgomery County's PEG transmission links to ensure that signal quality is maintained over new optical fibers throughout the year.

In Brunswick, Ohio, CTC performed extensive tests of the Brunswick cable television system as part of the franchise renewal with Cablevision. On the basis of CTC's testing report, CTC Principal Engineer Andrew Afflerbach served as an expert technical witness in the preliminary hearing for denial of the renewal. Dr. Afflerbach provided expert testimony regarding the status of the Cablevision system in Brunswick and its status relative to other cable systems around the country.

In Milwaukee, CTC performed testing and inspection of the Milwaukee cable system in support of the franchise renewal process.

For the Intercounty Cable Communications Commission (ICCA, representing Troy, Michigan and adjacent areas), CTC carried out a physical inspection and electronics test of the existing subscriber and institutional networks. CTC highlighted key issues for ICCA's renewal with TCI, including repair of the I-Net. CTC participated in the negotiations for renewal with TCI.
