How to check the version and issue of this document
The version and issue of the document are indicated by numbers, for example,
01.01.
The first two digits indicate the version. The version number increases each
time the document is updated to support a new software release. For example,
the first release of a document is 01.01. In the next software release cycle, the
first release of the same document is 02.01.
The second two digits indicate the issue. The issue number increases each time
the document is revised but rereleased in the same software release cycle. For
example, the second release of a document in the same software release cycle
is 01.02.
To determine which version of this document applies to the software in your
office and how documentation for your product is organized, consult the
release information in “Publication history” on page v of this document.

What precautionary messages mean
The types of precautionary messages used in Northern Telecom (Nortel)
documents include attention boxes and danger, warning, and caution
messages.
An attention box identifies information that is necessary for the proper
performance of a procedure or task or the correct interpretation of information
or data. Danger, warning, and caution messages indicate possible risks.
Examples of the precautionary messages follow.
ATTENTION Information needed to perform a task
CAUTION Possibility of service interruption or degradation
ATTENTION
IftheunusedDS-3portsarenotdeprovisionedbeforeaDS-1/VTMapper
is installed, the DS-1 traffic will not be carried through the DS-1/VT
Mapper, even though the DS-1/VT Mapper is properly provisioned.
CAUTION
Possible loss of service
Before continuing, confirm that you are removing the card
from the inactive unit of the peripheral module. Subscriber
service will be lost if you remove a card from the active unit.

xviii
297-8991-910 Standard 03.01 August 1999
CAUTION Possibility of equipment damage
CAUTION Possibility of static electricity damage
DANGER Possibility of personal injury
DANGER Possibility of electrocution
How commands, parameters, and responses are represented
Commands, parameters, and responses in this document conform to the
following conventions.
Input prompt (>)
An input prompt (>) indicates that the information that follows is a command:
>BSY
CAUTION
Damage to the backplane connector pins
Align the card before seating it, to avoid bending the
backplane connector pins. Use light thumb pressure to align
the card with the connectors. Next, use the levers on the card
to seat the card into the connectors
CAUTION
Static electricity damage
Wear a static discharge wrist strap connected to the wrist-
strap grounding point of a frame supervisory panel (FSP) or
amodularsupervisorypanel(MSP).Thisprecautionprotects
the cards against damage caused by static electricity.
DANGER
Risk of personal injury
Handle the card by the edges only. Do not touch the
components on the card. These components reach very high
temperatures, and can burn causing personal injury.
DANGER
Risk of electrocution
Do not open the front panel of the inverter unless fuses F1,
F2, and F3 have been removed. The inverter contains high
voltage lines. Until the fuses are removed, the high voltage
lines are active, and you risk being electrocuted.

Commands and fixed parameters
Commands and fixed parameters that are entered at a MAP terminal are shown
in uppercase letters:
>BSY CTRL ctrl_no
Variables
Variables are shown in lowercase letters:
>BSY CTRL ctrl_no
The letters or numbers that the variable represents must be entered. Each
variable is explained in a list that follows the command string.
Responses
Responses correspond to the MAP display and are shown in a different
typeface:
FP 3 Busy CTRL 0: Command request has been submitted.
FP 3 Busy CTRL 0: Command passed.
The following excerpt from a procedure shows the command syntax used in
this document:
