Architecture
Fully compatible with the T-BERD/MTS-4000 mainframe, the dual-bay Copper
Services Module can be optioned with a VDSL modem to provide support for
ADSL1/2/2+, VDSL1, and VDSL/VDSL2 triple-play deployments. The Copper
Services Module features dual Tip (A) and Ring (B) (T&R, A&B) and Ground
(Earth) interfaces. For the most accurate results, technicians can use specially
insulated cables to test higher-frequency services, such as VDSL2.

Figure 1: Standard copper qualification may show acceptable results for typical problem areas such as attenuation
and noise, but many issues impact copper quality in today’s demanding next-generation service environment,
particularly unterminated in-house wiring with bridged taps that lead to unexpected effects when using new
frequencies up to 30 MHz.
The T-BERD/MTS-4000 large, color GUI makes reading even the
most complex copper test results easy.
