analysis of video streams and packet
statistics on up to 10 streams in
Monitor Mode and 6 streams in
Terminate Mode, including video
mean opinion score (VMOS)
• Assesses VoIP packet quality and
voice quality rating using MOS and
R-Factor
• Tests data services, including ping,
trace route, and Web browser func-
tions from a 10/100/1000 Ethernet
port or optional xDSL modules
• Scans the virtual local area network
(VLAN) for current configuration
and activity
The JDSU T-BERD/MTS-4000 equipped with the Triple-Play Software option
delivers comprehensive Internet Protocol (IP) service-level testing in a rugged,
handheld, battery-operated platform that is ideal for Access and Home network
turn-up, troubleshooting, and maintenance.
The growth of triple-play services has changed the landscape of the telecommu-
nications industry through the creation of new opportunities, while also
introducing significant challenges for service providers. To remain competitive,
providers must efficiently deploy bundled voice, video, and data to the exacting
demands of customers—delivering on both quality of service (QoS) and experience
(QoE), while reducing operating expenses.
The T-BERD/MTS-4000 meets these challenges and more as the first multi-
application platform with fully integrated copper and fiber functionality that
addresses the complete set of requirements for triple-play, such as turn-up,
troubleshooting, and maintenance. The T-BERD/MTS-4000 Triple-Play Services
Software gives field service technicians who install and maintain triple-play service
over leading-edge fiber- and copper-based digital subscriber line (DSL) Access
networks a complete suite of essential testing tools in one unit.
Flexible connectivity, including universal serial bus (USB), high-speed
10/100/Gigabit Ethernet (GigE), Wireless Fidelity (WiFi), and Bluetooth, interfaces
make downloading software and offloading captured test data easier, thus
increasing productivity and baseline network performance.

Architecture
The T-BERD/MTS-4000 is designed for skilled field technicians who install and
maintain various next-generation fiber (FTTx) networks delivering triple-play
services that often require advanced troubleshooting, including in-depth physical
layer tests on copper or fiber—or increasingly both.

Applications
The T-BERD/MTS-4000 provides the full range of capabilities needed to test
today’s leading-edge FTTx and copper access networks plus the expandability
needed to test next-generation networks. The wide range of testing technologies
offered by the T-BERD/MTS-4000 provide all of the testing functions that
technicians need at every stage of the network lifecycle, from the physical layer to
the application layer, in a single handheld and rugged unit.
The T-BERD/MTS-4000 delivers an integrated approach to field testing with test
support for specific application use cases. Field-swappable modules are available
for multi-service testing and two modules can run simultaneously.
IP Video Testing
The T-BERD/MTS-4000 enables analysis of the video service (IPTV) stream
anywhere in the Access network using a DSL or Ethernet interface. With its
advanced performance monitoring features, the T-BERD/MTS-4000 accurately
measures video QoS and QoE using built-in tests for content, transport,
transaction, and physical link quality.

VoIP Testing
Technicians can use the T-BERD/MTS-4000 to turn up and troubleshoot voice
service (voice over IP [VoIP]) connectivity, feature availability, and voice quality.
They can also conduct IP ping, packet statistic, and trace route analysis to identify,
diagnose, and sectionalize VoIP network and equipment problems.

IP Data Testing
The T-BERD/MTS-4000 enables Internet connectivity testing using an integrated
Web browser and also performs required IP data tests (such as IP ping delay) to
verify bandwidth requirements for real-time applications and services (such as
online gaming and streaming video).

CoS Testing
With its advanced test capabilities that address each triple-play application QoS
metric, the T-BERD/MTS-4000 let carriers focus on effective Class of Service
(CoS) testing to ensure priority mapping for IP services. All three applications can
be run at the same time simulating mixed traffic flows. Interactions that violate
CoS rules can be identified quickly.
