Modular Design Release 4 can now be part of your
corporate telecommunications network. You can connect
to your existing private network, or to other
systems to form a network.
As a Network Manager, you understand your
network, but you want to know how can add to your
network. This chapter will explain:
how components behave in a network,
how they benefit your business, and
how you can configure to achieve those
benefits.

The Big Picture
E &M trunks
Private network
Public network .
Modular is a digital key system that enhanced
trunking abilities to broaden network access. Where a
company once had to rely on the public network to access a
small branch office, it can now reach the small office through
the corporate network.
A series of systems can be linked together to extend
the communications reach of a business. Authorized users
can also access tie-lines, Central Office lines, and
features from-outside the system.
Bits and pieces
The components that make network access possible are the
trunks and lines that uses. Target lines concentrate
incoming calls on fewer trunks, and three types of trunks
provide the network access:
E&M trunks handle incoming and outgoing traffic
between the system and the private network.
DID trunks route incoming calls from the public network
directly to telephones within the system,
without an attendant.
Loop Start trunks handle incoming and outgoing calls
between and the public network.

Benefits
Security
provides the security that expanded access
demands:
Control remote access to tie-lines, Central Office lines,
and system features by setting up a specific Class of
Service for each type of caller.
Restrict outgoing calls to certain telephone numbers or
area codes by applying dialing filters to lines and
telephones.
Screen remote callers by configuring trunks to answer
with DISA, a system response that requires callers to
enter a valid password.

To understand the capabilities that are described later in this
chapter, you need to know how the trunks and lines behave
in the
Modular system.
Bits and pieces 5
A trunk is a physical connection between the
and the outside world. A line is a flexible communication path
between a
one-to-many relationship between trunks and lines.
What this means is that one trunk does not have to represent
one line, but can represent several lines. You achieve this in
two ways:
1.
Auto-answer trunks
many lines, you configure it as Auto-answer. The
system answers calls and maps incoming digits
onto numbers that you define in programming. The
numbers can access the system, so that callers can
then use selected features or call out to another
destination (calling through the system). The numbers
can also access target lines that appear on one or

lines that can appear on a
other line. They are incoming lines only, and can not be
selected for outgoing calls. They are identified to the
system by their number. Any line with a number from
081 to 184 is a target line.
Of course, you can still have a one-to-one relationship
between a trunk and a line. In this case, you configure the
trunk as manual-answer.

An E&M trunk gives incoming and outgoing tie-line access
from other systems in the private network to the

Trunks
Loop Start trunks give you incoming and outgoing access to
the public network. However, you would typically configure
your system with Loop Start trunks for outgoing calls and
DID trunks for incoming calls. Loop Start trunks can be
configured as manual-answer or auto-answer.
When a call comes in on a manual-answer Loop start trunk,
it alerts at all telephones with that line appearance.
When a call comes in on an auto-answer Loop start trunk,

Dialing filters
You can use dialing filters to restrict the numbers that may
be dialed on any external line within your system.
You may specify up to 100 dialing filters for the system. A
dialing filter consists of up to 48 restrictions and their
associated exceptions.
Dialing within the system
To restrict dialing within the system, you can apply
filters to outgoing external lines (as line filters), to telephones
(as set filters), and to external lines on specific telephones
(as line per set filters).

The line per set filter overrides the line filter and set filter.
In the diagram on the previous page, a caller using line I
could not dial any long-distance number except to area
codes 212 and 718. A caller using line 3 could not dial any
long-distance number. A caller using line 5 could dial
distance numbers to area codes 212, 718, and 415.
Note: Set filters have no effect on the numbers that are
dialed out on an E&M trunk.

WARNING
Radio Frequency Interference
WARNING
This equipment generates, uses, and can radiate radio
frequency energy. If not installed and used in
accordance with the instruction manual, it may cause
interference to radio communications. It has been tested
and found to comply with the limits for a Class
computing device pursuant to Subpart J of Part 15 of the
FCC Rules, which are designed to provide reasonable
protection against such interference when operated in a
commercial environment. Operation of this equipment in
a residential area is likely to cause interference, in which
case the user, at his own expense, will be required to
take whatever measures may be required to correct the
interference. Each Meridian
System is assigned an FCC Registration Number and a
Ringer Equivalence designation. The number and
designation are printed on the Key Service Unit (KSU)
label on the front of the unit inside the door.

A
Key Telephone
Registration
The Meridian Key Telephone System is registered
with the FCC based upon compliance with Part 68 of its
rules. Connection of the Meridian
System to the nationwide telecommunications network is
made through a standard network interface jack that you
can order from your telephone company. Jacks for this type
of customer-provided equipment will not be provided on
party lines or coin lines.

Ringer Equivalence Number (REN)
Hearing Aid Compatibility
The FCC Registration Label, on the inside of the door on the
front of the Key Service Unit (KSU), includes the Ringer
Equivalence Number (REN). This number shows the
electrical load that your
KSU requires from your
telephone line. If the KSU requires more electrical current
than your telephone company’s central office equipment can
provide, your telephones may not ring and you may have
difficulty dialing telephone numbers.
Call the telephone company to find out the total REN allowed
for your telephone line(s).
Meridian telephones are Hearing Aid compatible, as
defined in Section 68.316 of Part 68 FCC Rules.
Telephone Company Registration
It is usually not necessary to call the telephone company
with information on the equipment before connecting the
Meridian
(KSU) to the telephone network but, if the telephone
company requires this information, provide the following:
l
Telephone number(s) to which the Key Service Unit (KSU)
will be connected.
