This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with
the instructions, may cause harmful interference to radio communications. However, there is
no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, the user is encouraged to try to correct the interference by
one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio/TV technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
FCC Caution: Any changes or modifications not expressly approved by the party responsible

FCC - Part 68
This equipment complies with Part 68 of the FCC rules. This equipment comes with a label
attached to it that contains, among other information, the FCC registration number and ringer
equivalence number (REN) for this equipment. If requested, this information must be provided
to the telephone company.
This equipment uses the following jacks: RJ-11.
The REN is used to determine the quantity of devices that may be connected to the telephone
line. Excessive RENs on the telephone line may result in the devices not ringing in response to
an incoming call. In most, but not all areas, the sum of the RENs should not exceed five (5.0).
To be certain of the number of devices that may be connected to the line, as determined by the
total RENs, contact the telephone company to determine the maximum REN for the calling
area.

2 Hardware Installation
Step 1 Connect the Line interface of the device and the Modem interface of the splitter through a telephone cable.
Connect the phone to the Phone interface of the splitter through a cable. Connect the incoming line to the
Line interface of the splitter.
The splitter has three interfaces:
– Line: Connect to a wall phone jack (RJ-11 jack)
– Modem: Connect to the ADSL jack of the device
– Phone: Connect to a telephone set.
Step 2 Connect the Ethernet interface of the device to the network card of the PC through an Ethernet cable
(MDI/MDIX).
I Note:
Use twisted-pair cables to connect wi th the hub or sw itch.
Step 3 Plug one end of the power adapter to the wall outlet and connect the other end to the Power interface of
the device.
Connection 1
Figure 1 displays the application diagram for the connection of the router, PC, splitter and the telephone sets, when
no telephone set is placed before the splitter.
Figure 1 Connection Diagram (without connecting telephone sets before the splitter)
Connection 2
Figure 2 displays the application diagram for the connection of the router, PC, splitter and the telephone sets, when
a telephone set is placed before the splitter.
5
SMC7901BRA4 User Manual
Figure 2 (with a telephone set before the splitter)
In the actual application, connection 1 is recommended.
I Note:
When connection 2 is used, the filter must be installed close to the telephone lines. Do not use the splitter instead of the filter.
Installing a telephone directly before the splitter may lead to a failure of connection between the device and the
office central, or cannot access into the Internet, or slow the connection speed. If you really need to add a telephone
set before the splitter, you have to add a microfilter before connecting to a telephone set. Do not connect several
telephones before the splitter. Do not connect several telephones with the microfilter.
