Overview of site testing 1-
This chapter describes the steps required to perform optional site testing on a
new system network element (NE) in a point-to-point, single-ended, or ring
system. Site testing for DS1-fed systems is described in DS1 Feeder Testing
Procedures, 323-3001-225, in this volume.
Site tests are usually performed in parallel with commissioning. The site that
is commissioned and tested first depends on your system configuration. If you
are commissioning a new or existing system with a portable operations
controller (OPC), it is recommended that you start at the remote fiber terminal
(RFT). If you are commissioning a new or existing system with a modular
OPC, it is recommended that you start in the central office, at the fiber central
office terminal (FCOT) or OPC shelf.
How to use this chapter
The procedures in this document are optional. Scan the following table to see
which figures apply to your configuration:
If you are site testing a new single-ended system in an existing OPC span of
control, then only the new RFT needs to be site tested (the existing OPC shelf
is part of the new system and is already tested when it is first put into service).
If you cannot successfully complete these procedures, contact your next level
of support.
The following table overviews the commissioning and testing process:

Site tests for fiber-fed systems.
- DS1 equipped configurations are tested using DS1 and optical
in-bay tests
- DS3 equipped configurations are tested using DS3 and optical
in-bay tests
- DS1 and DS3 equipped configurations are tested using DS3
test procedures first, followed by DS1 test procedures. Since
optical tests are performed during DS3 testing, the optical
tests in the DS1 test procedures can be omitted.
- DS1 and DS3 equipped configurations are tested using
temporary DS1 or DS3 equipment. However, it is
recommended that DS3 testing be used since it can be
performed in a shorter period of time. In either case, since the
mappers are not connected to a cross-connect panel, DS1 or
DS3 continuity tests do not have to be performed. Similarly,
since there are no protection mappers present, DS1 or DS3
protection switching tests do not have to be performed.

Radio-frequency emissions notice
The following regulatory notice applies to AccessNode equipment:
Note: This equipment has been tested and found to comply with the limits
for a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when operated in a commercial environment. This equipment
generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a
residential area may cause harmful interference, in which case the user will
be required to correct the interference at his own expense.
Static electricity
It is usual for static electrical charges to build up on the body if a person walks
a short distance. This buildup of static electricity is sufficient to damage some
circuit packs if it is not properly discharged first. Circuit packs that are
sensitive to damage by static electricity should be packaged in antistatic
material. The following precautions are recommended.
Handling circuit packs
Units that are sensitive to static electricity are marked in their antistatic
shipping bags with the following symbol:
CAUTION
Risk of equipment damage
Wear a grounded antistatic wrist strap or equivalent
protection when handling circuit packs, to avoid damaging
electronic parts.

Overview of site testing 1-5
AccessNode Site Testing Procedures 323-3001-221 Issue 2.0
To avoid static electrical damage when handling circuit packs, follow these
rules:
• Do not remove circuit packs from their antistatic packages unless you are
using antistatic protection, such as wearing an antistatic wrist strap. The
wrist strap is attached to a long cord, that must terminate at a good ground
source, so that static buildup is harmlessly discharged. Alternative
antistatic methods include conductive carpet, conductive shoes, or heel
grounders. Use the equipment recommended by your company.
• Handle each circuit pack by the faceplate or stiffener. Do not touch
electrical connections, pins, or soldered surfaces.
Protect optical connectors by covering them with clean dust caps.
Storing and transporting circuit packs
When storing and transporting circuit packs, follow these rules:
• Never transport, stack or store circuit packs without first replacing them in
their antistatic material and original shipping package. This avoids
physical damage and accumulation of dirt or dust on goldplated contacts.
Be careful not to damage any parts when inserting the circuit pack into its
packaging.
• Avoid storage in areas where the relative humidity can exceed 95% and
where the temperature can exceed 70°C, because boards may warp or
corrode.
Laser radiation
AccessNode equipment and associated optical test sets use laser sources that
emit light energy into fiber cables. This energy is within the red (visible) and
infrared (invisible) regions of the electromagnetic spectrum.
Laser products are subject to federal and state or provincial regulations, and
local practices. Regulation 21 CFR 1040 of the U.S. Bureau of Radiological
Health requires manufacturers to certify each laser product as Class I, II, III,
or IV, depending upon the characteristics of the laser radiation emitted. In
terms of health and safety, Class I products present the least hazard (none at
all), while Class IV products present the greatest hazard.
CAUTION
Risk of eye damage
At all times when handling optical fibers, follow the safety
procedures recommended by your company.
Read and follow the precautions below, to decrease the risk
of exposure to laser radiation.

1-6 Overview of site testing
AccessNode Vol 3B 323-3001-221 Issue 2.0
Although Nortel S/DMS optical products have a Class I certification,
hazardous exposure to laser radiation could occur when fibers that
interconnect system components are disconnected or broken. Certain
procedures carried out during testing require the handling of optical fibers
without dust caps, and therefore increase the risk of exposure. Exposure to
either visible or invisible laser light could cause eye damage under certain
conditions.
Equipment warning label
The equipment label is located in the top left corner of the back cover. It reads
as follows:
To be installed only in restricted access areas (dedicated
equipmentrooms, equipment closets,orthelike)in accordance
with articles 110-16, 110-17, and 110-18 of the National
Electrical Code, ANSI/NFPA No. 70.
Avoid direct exposure to
beam. Invisible light can
blind. Keep all optical
connectors capped.
The caution label at the right appears on the
optical interfacecard, neartheoptical connector,
and should be complied with.

DS3 tests, STS-1 tests, and optical
in-bay tests 2-
This chapter describes how to test DS3 or STS-1 and optical equipment at a
system network element (NE) supporting DS3 or STS-1 interfaces or a mix of
DS1, DS3, and STS-1 interfaces.
You can test NEs that are not equipped with any DS1/VT or DS3 mappers or
STS-1 interface cards by installing temporary DS1, DS3, STS-1 equipment
and using the appropriate procedures. However, it is recommended that you
use DS3 or STS-1 test procedures since they can be performed in a shorter
period of time than the DS1 tests. Because there are no connections to a
DSX-3/STS-1 cross-connect panel, digital signal continuity tests are not
required. Because there is no protection mapper present, digital protection
switching is not required. As a result, only optical receiver sensitivity and
optical protection switching tests must be performed on systems not normally
equipped with DS1s, DS3s, or STS-1s.
These procedures cover local in-bay tests on equipment located at a single NE
and can form the basis for customer acceptance tests. Unless otherwise noted,
one technician can perform these tests. End-to-end testing (between two NEs)
of optical and digital equipment in a universal configuration is described in
System Testing Procedures, 323-3001-222, in this volume.
Note 1: The Series 800A Outside Plant Cabinet and single-ended systems
do not support DS3s.
Note 2: STS-1 tributaries are supported only on a TN_BLSR shelf.

AccessNode Vol 3B 323-3001-221 Issue 2.0
How to use this chapter
Refer to the document task list in Chapter 1. The document task list identifies
the procedures that must be performed.
If you cannot successfully complete these procedures, contact your next level
of support.
DS3/STS-1 group and slot associations
DS3 or STS-1 circuit packs are in the lower level of the common equipment
shelf. BNC input and output (I/O) cards are in the upper level. With DS3
mappers or STS-1 interface cards, “g1” refers to a group of modules including
a working circuit pack and its corresponding three BNC I/O cards. Similarly,
“p” refers to the group of modules including the protection circuit pack and the
protection switcher cards.
The DS3 or STS-1 capacity of the system is dependent on the shelf type and
the DS1, DS3, or STS-1 mix as well as the traffic that your system is carrying.
For details about determining the capacity of your configuration, see Optional
Commissioning Procedures, 323-3001-220, in this volume.
