CE NOTICE
We certify that the apparatus identified in this document conforms to the require-
ments of Council Directive 1999/5/EC on the approximation of the laws of the
member states relating to Radio and Telecommunication Terminal Equipment
and the mutual recognition of their conformity.
RADIO AND TV INTERFERENCE
This equipment generates and uses radio frequency energy, and if not installed
and used properly—that is, in strict accordance with the manufacturer's instruc-
tions—may cause interference to radio and television reception. This equipment
has been tested and found to comply with the limits for a Class A computing
device in accordance with the specifications in Subpart B of Part 15 of FCC rules,
which are designed to provide reasonable protection from such interference in a
commercial installation. However, there is no guarantee that interference will not
occur in a particular installation. If the equipment causes interference to radio or
television reception, which can be determined by disconnecting the cables, try to
correct the interference by one or more of the following measures: moving the
computing equipment away from the receiver, re-orienting the receiving antenna,
and/or plugging the receiving equipment into a different AC outlet (such that the
computing equipment and receiver are on different branches).
FCC PART 68
This equipment complies with Part 68 of FCC rules and the requirements adopted
by ACTA. On the bottom side of this equipment is a label that contains—among
other information—a product identifier in the format US: AAAEQ##TXXXX. If
requested, this number must be provided to the telephone company.
The method used to connect this equipment to the premises wiring and telephone
network must comply with the applicable FCC Part 68 rules and requirements
adopted by the ACTA.
If this equipment causes harm to the telephone network, the telephone company
will notify you in advance that temporary discontinuance of service may be
required. But if advance notice isn’t practical, the telephone company will notify
the customer as soon as possible. Also, you will be advised of your right to file a
complaint with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, opera-
tions or procedures that could affect the operation of the equipment. If this hap-
pens the telephone company will provide advance notice in order for you to make
necessary modifications to maintain uninterrupted service.

If trouble is experienced with this equipment, for repair or warranty information,
please contact our company. If the equipment is causing harm to the telephone
network, the telephone company may request that you disconnect the equipment
until the problem is resolved.
Connection to party line service is subject to state tariffs. Contact the state public
utility commission, public service commission or corporation commission for
information.
INDUSTRY CANADA NOTICE
This equipment meets the applicable Industry Canada Terminal Equipment Tech-
nical Specifications. This is confirmed by the registration number. The abbrevia-
tion, IC, before the registration number signifies that registration was performed
based on a Declaration of Conformity indicating that Industry Canada technical
specifications were met. It does not imply that Industry Canada approved the
equipment.
This Declaration of Conformity means that the equipment meets certain telecom-
munications network protective, operational and safety requirements. The
Department does not guarantee the equipment will operate to the user's satisfac-
tion. Before installing this equipment, users should ensure that it is permissible to
be connected to the facilities of the local telecommunications company. The
equipment must also be installed using an acceptable method of connection. In
some cases, the company’s inside wiring associated with a single line individual
service may be extended by means of a certified connector assembly (telephone
extension cord). The customer should be aware that compliance with the above
condition may not prevent degradation of service in some situations. Repairs to
some certified equipment should be made by an authorized maintenance facility
designated by the supplier. Any repairs or alterations made by the user to this
equipment, or equipment malfunctions, may give the telecommunications com-
pany cause to request the user to disconnect the equipment. Users should ensure
for their own protection that the ground connections of the power utility, tele-
phone lines and internal metallic water pipe system, are connected together. This
protection may be particularly important in rural areas.

2.1 Connecting Power
Your T1/E1 Extender comes with an external AC adaptor with a detachable
power cord.
To connect power to the T1/E1 Extender:
1. Connect the female plug of the AC power cord to the AC adaptor provided.
2. Connect the barrel-type connector of the AC adaptor to the Power connec-
tor on the T1/E1 Extender.
3. Insert the male plug of the AC power cord into the AC power outlet (100-
240 VAC).
4. Verify that the Power LED on the front panel illuminates and remains lit.
2.2 Power Input Connector
The T1/E1 Extender comes with an AC power supply.
• The supplies connection to the T1/E1 Extender is a 2.5 mm barrel receptacle
with the center conductor positive (see Figure 3).

The external AC adaptor shall be a listed limited power
source that incorporates a disconnect device and shall
be positioned within easy reach of the operator. Ensure
that the AC power cable meets all applicable standards
for the country in which it is to be installed, and that it
is connected to a wall outlet which has earth ground.
CAUTION

2.3 Connecting the Line Port
Follow the steps below to connect the line port:
1. Obtain a single-twisted pair cable with an RJ-45 plug connector at each
end.
2. Plug one end of the cable into the RJ-45 socket (labeled Line) on the T1/E1
Extender .
3. When the remote and local extender units synchronize, the front-panel Link
LED will turn on.
2.4 Connecting the Circuit Interface
Your T1/E1 Extender comes with either an RJ-48C or an RJ-48C and dual BNC
for connection to a T1 or E1:
•
Model MT196A-E1 - E1: 120-Ohm RJ-48C and dual 75-Ohm BNC connec-
tors
•
Model MT195A-T1 - T1: RJ-48C
To connect the twisted pair cable to the T1/E1 port:
1. Attach the male connector of the twisted pair cable to the female RJ-48
connector on the T1/E1 Extender.
2. Attach the other end of the cable to the RJ-48 connector on the local T1 or
E1.
Note When attaching the T1/E1 Extender directly to a T1/E1 circuit, a straight
through twisted pair cable can be used. When attaching the MT196A-
E1/R or MT195A-T1/R to a device, please use the enclosed T1/E1 cross
over cable for proper operation.
Note The unit marked as MT196A-E1/L or MT195A-T1/L is configured by
default to accept timing from the T1/E1 circuit. The MT196A-E1/R or
MT195A-T1/R unit then recovers this timing from the line in order to
ensure synchronization of the T1/E1 circuit over the extenders.
The interconnecting cables shall be acceptable for
external use and shall be rated for the proper applica-
tion with respect to voltage, current, anticipated tem-
perature, flammability, and mechanical serviceability.
CAUTION

3. Operation
Once the T1/E1 Extenders are properly installed, they should operate transpar-
ently. No user settings required. This section describes reading the LED status
monitors.
3.1 Front Panel LED Status Monitors
Models MT196A-E1 and MT195A-T1 feature three front-panel LEDs that moni-
tor power, Ethernet signals, and the CopperLink connection. Figure 4 shows the
front panel location of each LED. Table 1 describes the LED functions.
