OC3port Plus Features and Capabilities
effectively monitor and test OC3 networks from any access point. The OC3port
Plus also provides the following:
• OC3 pointer control and monitoring
• Support for SONET and SDH framing formats
• Date and time stamping of OC3 alarm occurrences
• A passive monitoring mode, which allows for non-intrusive testing
• Automatic testing of OC3 circuits so that you can obtain immediate pass/fail
results and quickly assess problems with SONET networks.
In addition, the OC3port Plus offers a comprehensive set of advanced ATM testing
capabilities, which includes:
• Automatic scanning of active virtual circuits
• Ability to transmit up to eight ATM traffic sources simultaneously
• Quality of Service tests: Cell Delay, Cell Variation, and Cell Loss
• Cell payload capture and viewing
• Various cell transmission modes, including single cell, programmable burst
size, and constant rate
1
• Transmission of ATM traffic that simulates CBR, VBR, and UBR service
categories with programmable random, poisson, or constant traffic distribution
patterns
• AAL type recognition
• OAM cell transmit and monitoring of AIS, RDI, and loopback F4 and F5
flows
• Quality of service measurements: CTD (mean, max), CDV (max), CLR, and
CMR.
In addition to advanced diagnostic and testing capabilities, the OC3port Plus gives
you immediate feedback on the condition of any OC3 circuits under test through
its front-panel LEDs. The tester also lets you store and print test results, making it
possible for you to gather and later examine network statistics.
For long-term monitoring, the OC3port Plus can be connected to a network, which
can be monitored remotely through a modem connected to a PC with Fluke’s
remote control software. This gives you the added advantage of being able to leave
the OC3port Plus connected at a customer premise or central office location and
dial into the tester from a PC or laptop computer from a central monitoring
location.

Getting Acquainted with the OC3port Plus Menus
The OC3port Plus is a menu driven system. Each time you power on the unit, a
series of self-tests and automatic ATM and SONET diagnostic tests is performed.
Note
The single-mode version of the OC3port Plus contains a laser
transmitting device. As a safety precaution, this transmitter is off
when the unit is powered on. You must turn the laser on each time
you turn on the unit. It remains on until you shut off the unit.
See "Turning on the Laser Transmitter" in this chapter for
instructions on how to turn on the laser transmitter. Note that the
laser comes on automatically if the OC3port Plus detects an input
signal while you are running the automatic diagnostic tests.
While the automatic tests are running, you see displays similar to this:

Turning Off the Automatic Diagnostic Tests
When you first power on the OC3port Plus, it automatically conducts a series of
self-tests and diagnostic tests that assess the basic health of any OC3 signal
provided to its input connector. If no signal is present or if theOC3port Plus is not
yet connected to a network, the tester waits until a signal is detected.
After a signal is detected, the OC3port Plus begins a 25-second analysis of the
signal and its format. Then, the OC3port Plus displays a set of summary statistics
for both ATM and SONET. For information on the results provided by these tests,
see "Running the Automatic Diagnostic Tests" later in this chapter.
The automatic tests are conducted and results are displayed every time you power
on the OC3port Plus unless you prevent the tester from running them. The
instructions in this section show you how to do this.
Note
You can run the automatic tests under your own control. For
information on how to do this, see "Running the Automatic
Diagnostic Tests" later in this chapter.
If you want to prevent the OC3port Plus from running the diagnostic tests every
time you turn on the tester, do the following:

Users Manual
Parameter Sets
The OC3port Plus can store in memory up to two distinct groups of user-defined
configurations under the respective labels Parameter Set 1and 2. Each group can
contain any of the programmable options available on the OC3port Plus. These
include any setups you create, the parameters and settings for tests, transmission
modes, ATM states, and BERT test patterns, to name a few.
Parameter sets are useful when you need to retain test setups and configurations
that you use frequently. For example, you can create one parameter set for BERT
testing and the other for ATM testing. Parameter sets are also useful when more
than one person uses the unit. Each user can store his or her own user definitions
for tests and setups in a separate parameter set.
You can use only one parameter set at any given time, but you can easily switch to
the other set and begin using its setups.
This section shows you how to do the following:
• Create a parameter set
• Name a parameter set
• Switch between parameter sets
• Edit a parameter set.
Creating a Parameter Set
When you turn on the OC3port Plus, it uses the parameter set that
was in use when the unit was last turned off. If this is the first time
that you are using the tester, the parameter set that is active when
you turn on the unit is Parameter Set 1.

suggest that you use the remaining time to immediately store any current test
results and then recharge the unit.
If the battery does not charge, contact Fluke Customer Service for
replacement batteries.
You can connect the tester to the supplied AC adapter/charger and charge it
without shutting it off. On a full battery charge, which takes between 12 to 14
hours, the OC3port Plus will run for approximately three hours.
The AC adapter/charger should never be disconnected
while the OC3port Plus is powered on. This can cause
corruption of current or stored test results.

SONET/SDH Configuration and Testing
Introduction
The OC3port Plus constantly monitors the SONET/SDH framing structure to
detect errors. This chapter describes how to set up your OC3port Plus to test
STS-3c and STM-1 signals. It shows you how to monitor these signals and
describes the various results provided by the OC3port Plus about the transmitted
signals. Finally, this chapter describes the alarms that you can transmit. It shows
you how to generate an alarm and view information about received alarms.
Configuring the Framing Format
If your OC3port Plus has been factory configured and shipped to work on a
SONET OC3 STM-1 network, you have the ability to do testing that is compliant
with
Synchronous Digital Hierarchy (SDH) standards. This section describes the
major differences between SONET OC3 STS-3c and SDH STM-1 standards and
then shows you how to configure the framing format on the OC3port Plus so that
you can work with SDH-compliant equipment.
Differences between SONET OC3 STS-3c and SDH STM-1
The differences between SONET OC3 STS-3c and SDH STM-1 standards are
minimal. Both technologies operate at 155 Mbits per second. SONET OC3
networks use STS-3c frames. SDH networks, on the other hand, use STM-1
frames. ATM traffic is carried on both of these formats and the formats are nearly
identical.
Introduction
4
Although the differences are minor, STS-3c frames can only be used on SONET
OC3 networks, and STM-1 frames can only be used on SDH networks. The
following information summarizes the differences between the SONET and SDHcompliant networks:
• To configure the OC3port Plus for compliance with SDH standards, you need
to change the framing format. When you choose STS as the framing format,
the OC3port Plus automatically sets the S-bits to "00" for SONET STS-3c
networks. When you choose STM as the framing format, the OC3port Plus
automatically sets the S-bits to "10" for the SDH STM-1 networks.
Note
After you choose a framing format, you can (for diagnostic
purposes) override the S-bit settings used by the framing format.
To do this, see "Changing the S-Bit Values" later in this chapter
for information on how to do this.

Users Manual
• In SONET, the Path FERF alarm is indicated by setting the Path FEBE bits in
the STS-3c frames to "1001". In the SDH STM-1 networks, the 5th bit in the
G1 byte is set to "1".
• SDH networks require equipment to declare a Path FERF alarm whenever the
alarm condition is present for five consecutive frames.
• In the SONET network, there is a YELLOW alarm indication. In the SDH
networks, there is no such alarm.

Changing the S-Bit Values (optional)
When you select a framing format, the correct S-bit values for your network are
automatically set. However, it is possible to set the OC3port Plus for either
SONET or SDH operation and then use the S-bit values to indicate the opposite
frame type (that is, you can set framing to STM and then set the S-bits to "00" for
SONET). Such a configuration can be used to diagnose various network
problems. However, as noted earlier, changing the framing affects more than just
the S-bit values.

order to respond to small frequency differences among various elements in a
communications network. For this reason, you may need to modify the value of
the payload pointer to determine the location of the first byte of the SPE. This
