3.0 Safety Information
eCPRI Testing User Manual D07-00-131P RevA00
Page 6 of 53
Safety precautions should be observed during all phases of operation of this instrument. The instrument has been designed to
ensure safe operation however please observe all safety markings and instructions. Do not operate the instrument in the presence
of flammable gases or fumes or any other combustible environment. VeEX Inc. assumes no liability for the customer's failure to
comply with safety precautions and requirements.
Optical Connectors
The test sets display a laser warning icon when the laser source is active to alert the user about a potentially dangerous situation. It
is recommended to:
1. Deactivate the laser before connecting or disconnecting optical cables or patchcords.
2. Never look directly into an optical patchcord or an optical connector interface (SFP+) while the laser is enabled. Even though
optical transceivers are typically fitted with Class 1 lasers, which are considered eye safe, optical radiation for an extended
period can cause irreparable damage to the eyes.
3. Never use a fiber microscope to check the optical connectors when the laser source is active.
Safe Module Handling
While replacing test modules, all work on the open panel must be performed only by suitably qualified personnel who is familiar with
the dangers both to people and to the instrument itself.
Modules are not hot swappable. The platform must be turned off and unplugged from VAC mains when removing or inserting
test modules.
For safety and EMC (Electromagnetic Compatibility), empty module slots must be properly covered with blank panel covers.
Prevent foreign objects from entering the unit, before, during and after module exchange or re-configuration process. They
could create short circuits or damage internal fans.
Always store test modules by themselves in individual ESD protected packaging (with no loose elements, like screws or
tools).
Lithium-ion Battery Precautions
Lithium-ion (Li-ion) battery packs are compact and offer high capacity and autonomy, which make them ideal for demanding
applications, like providing long lasting power to portable test equipment. For safety reasons, due to their high energy concentration,
these batteries packs and products containing them must be used, charged, handled, and stored properly, according to the
manufacturer’s recommendations.
Li-ion battery packs contain individual Li-ion cells as well as battery monitoring and protection circuitry, sealed in its plastic container
that shall not be disassembled or serviced.
The test set unit's battery pack is also fitted with a safety connector to prevent accidental short circuits and reverse polarity.
Always charge the unit's battery pack inside the test platform battery bay using the AC/DC adapter supplied by VeEX.
Do not charge or use the battery pack if any mechanical damage is suspected (shock, impact, puncture, crack, etc).
Do not continue charging the battery if it does not recharge within the expected charging time
Storage: For long term storage, the battery pack should be stored at 20°C/68°F (room temperature), charged to about 30 to
50% of its capacity. Spare battery packs should be charged and used at least once a year to prevent over-discharge (rotate
them regularly).
It is recommended to charge and use battery packs at least every three months. Battery packs shall not go without recharging
(reconditioning) for more than six months.
After extended storage, battery packs may reach a deep discharge state or enter into sleep mode. For safety reasons, Li-ion
batteries in deep discharge state may limit the initial charging current (pre-recharge) before starting their regular fast charging
cycle. The pre-charging state may take several hours.
eCPRI Testing User Manual D07-00-131P RevA00
Page 7 of 53
Air transportation of Li-ion batteries is regulated by United Nations' International Air Transportation Association (IATA)
Dangerous Goods Regulations and by country-specific regulations. Please check local regulations and with common carriers
before shipping Li-ion battery packs or products containing relatively large Li-ion battery packs.
Electrical Connectors
Telephone lines may carry dangerous voltages. Always connect the electrical test ports to known test interfaces which carry low
level signals.
ESD: Electrostatic Discharge Sensitive Equipment
Test modules could be affected by electrostatic discharge. To minimize the risk of damage
when replacing or handling test modules, make sure to follow proper ESD procedures and
dissipate any electrostatic charge from your body and tools and the use proper grounding gear.
Perform all work at a workplace that is protected against electrostatic build-up and
discharging.
Never touch any exposed contacts, printed circuit boards or electronic components.
Always store test modules in ESD protected packaging.
Wear ESD protection and grounding gear when:
Inserting, extracting, or handling test modules.
Inserting or removing SFPs, XFPs, QSFPs, or CFPs from the platform.
Connecting or disconnecting cables from modules or platform.

6.1 eCPRI Testing Overview
The Common Public Radio Interface (CPRI) forum introduced a new more stringent Ethernet packet based fronthaul interface,
eCPRI, due to limitations for 5G deployments based on traditional CPRI or OBSAI.
To ensure that 5G network's strict requirements are met in the fronthaul, the eCPRI Transport Network requirement document
establishes classes of service for data and C&M traffic. With full line rate eCPRI traffic generation capabilities and high accuracy
one-way latency measurements, the eCPRI test application provides the tools necessary to ensure that the eCPRI transport network
is ready for 5G deployments.
CPRI Mobile Fronthaul Evolution
This protocol has been developed by Ericsson AB, Huawei Technologies Co. Ltd, NEC Corporation, Alcatel Lucent and Nokia
Siemens. The standard is public and can be downloaded from

Page 19 of 53
6.4.1 Setup
To access Throughput testing features, tap Throughput from the Home menu.
Overview:
This application is very useful in verifying the transport of traffic with different prioritization settings across a network link. The test
helps verify that the network can handle high priority traffic and low priority traffic accordingly.
The Throughput application performs the following measurements:
Throughput performance
Frame Loss analysis
Delay analysis
Frame/Packet arrival analysis
Received Traffic Type analysis
Received Traffic Frame Size analysis.
On the transmit side, the Throughput application currently allows up to 32 streams with its MAC and IP address, VLAN tags (up to
3), bandwidth/rate, frame size, and L2 and/or L4 quality of service (QoS) parameters. On the receiver end, the traffic is analyzed on
a per stream basis as well as a global or aggregate measurement.
eCPRI Throughput testing at Layer 2 and 4 is supported. Throughput can be configured to use either stress patterns or user defined
test patterns to simulate various conditions. The test layer, frame header, traffic profile, error injection, and control settings of the farend device (if applicable) must be configured prior to testing.

Throughput General Setup
Page 2 features One Way Delay measurement and Service Disruption Test (SDT) measurement settings.
Delay Measurement Mode: Enable/disable the round trip delay measurement. It should only be enabled when running the
test to a remote loopback.
RTD Unit Auto Scale: ON/OFF
Histogram: Enable / Disable
Sampling Period: 1sec, 10secs, 30secs, 1min, 10min, 30min, 1hr. Defines how often the RTD (round trip delay)
measurement is evaluated against the RTD threshold.
Threshold (Max RTD allowed): Input the value in us, ms or sec. Defines the maximum allowed round trip delay value. If the
RTD value exceeds the threshold, an event is logged with corresponding time stamp.
Save Histogram: Enable/Disable
SDT Measurement: Enable/Disable. The Service Disruption Test is triggered based on user established thresholds.
SDT Violation Threshold (us):Triggers an SDT Violation event in the event log. This is helpful for historical purposes
during any given test. If the measured SDT is equivalent or greater than the configured threshold an SDT Violation
event is counted.
SDT Measurement Trigger (>us): Any inter-frame gap that is equivalent or greater than the configured threshold will
trigger the SDT measurement. This is useful if a known threshold is expected from a given network under test. For
example, if the known switchover time is 50ms, the trigger can be set to a value slightly below 50ms to assure that the
SDT is measured.
