vendor products may or may not operate satisfactorily. Multi-Tech System’s recommended vendor products only indicate
that the product has been tested in controlled conditions and were found to perform satisfactorily.
Surface mount ferrites are used on T&R (Tip and Ring) to mitigate emission levels out the RJ-11 cable. 220pF capacitors
are also used on T&R to reduce the common mode emissions that may be present in certain systems. See the Tip and
Ring drawings in each analog SocketModem chapter.
The ferrite and capacitors also aid in reducing the effects of transients that may be present on the line.
Note: These parts are RoHS compliant.

The RJ-11 connector must meet FCC Part 68 requirements. Refer to FCC Part 68 section 68.500 subpart F for connector
specifications. A self-healing fuse is used in series with line to help prevent damage to the DAA circuit. This fuse is
required in order to meet compliance regulations.
Note: See Application Notes at the end of each SocketModem chapter.
