CAUTION
Risk of electric shock. Voltages up to 140 VDC (with reference to
ground) may be present on telecommunications circuits.
- PRECAUTIONARY STATEMENT -
- Never install telephone wiring during a lightning storm.
- Never install telephone jacks in wet locations unless the jack is
specifically designed for wet locations.
- Never touch uninsulated telephone wires or terminals unless
the phone line has been disconnected at the network interface.
- Use caution when installing or modifying telephone lines.
- This equipment is intended to be used behind devices that
provide primary lightning protection.
- This installation should conform to Local Codes and NEC
requirements.
- This equipment is to be installed in a restricted access location.
- CAUTION -
Never apply power until all installer connections are made.

Mounting the Module
The 3115-80 is a 200 MECHANICS
-type plug-in module that
mounts in a 200- or 400-mechanics-type mounting assembly (or
equivalent mounting which matches the pin-out plan of the
module). Before installing the module, set any options in the de-
sired position(s). Align the module with the mounting or
assembly card guides above and below the unit and insert as far
as it will go into the slot connector.

Making Installer Connections
No installer connections are required other than inserting the
module into the card-edge connector in the shelf or assembly.
The unit makes electrical connections to external equipment
when installed and properly seated in the 56-pin card-edge con-
nector in the mounting assembly. The pin-outs used by the NIU
are listed in Table 6.
- CAUTION -
Use care when installing and removing modules -
do not force
into place
. If a module resists insertion, remove it and check
for obstructions in/near the connectors and mounting slots,
then carefully re-align and gently re-insert the module.

SET-UP AND OPERATION
9.1
Craft Terminal Setup and Operation
9.1.1
The front-panel craft interface port allows the craft to
configure the unit for a particular application, view the stored T1
performance statistics, as well as graphically view circuit status
and perform various test routines. Each menu provides an asso-
ciated HELP screen that explains the function and use of the
menu. HELP screens are accessed by pressing (?).
9.1.2
The craft interface port is a DB-9 connector with an
electrical RS-232 female interface in a DCE configuration. The
craft device can be a terminal operating in the VT-100 protocol
or a PC running a VT-100 terminal emulator program. If a
VT-100 terminal is used a null-modem" cable may be required
between the terminal and the NIU. If a PC with VT-100 emula-
tor program is used, a standard RS-232 cable can be used. The
RS-232 port should be set up for 9600 baud, no parity, and one
stop bit (NP,1S). The electrical connections to the craft port are
shown in Figure 10.
9.2
Menus and Screens
9.2.1
MAIN Menu Screen
Once the terminal or PC is connected to the craft interface port,
the MAIN menu should appear. The MAIN menu provides the
NIU model number, CLEI code, Technical Service contact tele-
phone number, as well as navigation buttons to other screens.
The Model Number and CLEI Code are set at the factory and
cannot be changed. The MAIN menu is illustrated in Figure 14.
To return to the MAIN menu screen from any other screen enter
<Esc>.
9.2.2
PROVISIONING Menu Screen
The PROVISIONING screen (Figure 15) is used to configure
the unit’s options. To reach this screen from the MAIN menu,
type <O>. The NIU is set from the factory to a standard config-
uration. All options in the menu can be set and queried
remotely. For each option, the display shows the CURRENT"
configuration as well as a NEW" field that shows what the op-
