Important Safety Instructions
1. Read and follow all warning notices and instructions marked on the product or included in the manual.
2. This product is intended to be used with a 3-wire grounding type plug – a plug which has a grounding pin. This is
a safety feature. Equipment grounding is vital to ensure safe operation. Do not defeat the purpose of the
grounding type plug by modifying the plug or using an adapter.
Prior to installation, use an outlet tester or a voltmeter to check the ac receptacle for the presence of earth
ground. If the receptacle is not properly grounded, the installation must not continue until a qualified electrician
has corrected the problem.
If a 3-wire grounding type power source is not available, consult a qualified electrician to determine another
method of grounding the equipment.
3. Slots and openings in the cabinet are provided for ventilation. To ensure reliable operation of the product and to
protect it from overheating, these slots and openings must not be blocked or covered.
4. Do not allow anything to rest on the power cord and do not locate the product where persons will walk on the
power cord.
5. Do not attempt to service this product yourself, as opening or removing covers may expose you to dangerous
high voltage points or other risks. Refer all servicing to qualified service personnel.
6. General purpose cables are provided with this product. Special cables, which may be required by the regulatory
inspection authority for the installation site, are the responsibility of the customer.
7. When installed in the final configuration, the product must comply with the applicable Safety Standards and
regulatory requirements of the country in which it is installed. If necessary, consult with the appropriate regulatory
agencies and inspection authorities to ensure compliance.
8. A rare phenomenon can create a voltage potential between the earth grounds of two or more buildings. If
products installed in separate buildings are interconnected, the voltage potential may cause a hazardous
condition. Consult a qualified electrical consultant to determine whether or not this phenomenon exists and, if
necessary, implement corrective action prior to interconnecting the products.
9. In addition, if the equipment is to be used with telecommunications circuits, take the following precautions:
—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 telephone line has been disconnected at the
network interface.
—Use caution when installing or modifying telephone lines.
—Avoid using a telephone (other than a cordless type) during an electrical storm. There may be a remote risk of
electric shock from lightning.
—Do not use the telephone to report a gas leak in the vicinity of the leak.

User Interface 2
Introduction
The T1 access unit uses menu-driven asynchronous (async) terminal interface
menus and screens. Along with the LED status indicators on the front panel, the
menu-driven interface provides feedback and status on the:
T1 access unit
DSX-1 and Network T1 interfaces
Synchronous data ports
Voice ports
User Interface Access
You can access the user interface:
Locally through a direct connection to the communications port via an async
terminal (or other VT100-compatible terminal) or PC emulation.
Remotely through a Telnet session, although only one user interface session
may be active at one time.
Network Management
Manage the T1 access unit via an SNMP management system connected to the
communications port or through a remote in-band connection.
Menu Hierarchy
The menu hierarchy represents the organization of the system’s menus and
screens. Refer to the enclosed
Quick Reference for a pictorial view of the menu
hierarchy.

Quick Reference provided with this document to guide you through
menu selections.
Selecting a Field
Once you have reached the desired menu or screen, select a field to view,
change, or issue a command. Select a field from within a menu in the same way
you select from a menu – press the Tab or right arrow key.
Example:
Selecting Control from the Main Menu, selecting Administer Logins, then entering
or changing security information.
Making Input Selections
You can enter information into a field in one of several ways. Once the field is
selected, you can:
HManually type in (enter) the field value or command.
Example:
Entering abc as a user’s Login ID on the Administer Logins screen (from the
Control menu/branch).
HType in (enter) the first letter(s) of a field value or command, using the
character matching feature.
Example:
When configuring an FXS voice port’s operating mode with the Operating
Mode configuration option/field selected (values FXS, FXSDN,
FXSDN/WINK, PLAR and DPO), entering f or F displays the first value
starting with f – FXS. In this example, entering
fxsd or FXSD would display
FXSDN as the selection.
HSwitch from the screen area to the screen function area and select or enter
the designated screen function key. See
Switching Between Screen Work
Areas
for an example.
