According to:  
TIA-968-A and CS-03 Part 1, issue 9 
This equipment complies with Part 68 of the FCC rules and  the requirements adopted by the ACTA.  
On the left 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.
A plug and jack 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. A compliant 
telephone cord and modular plug is provided with this product.  It is designed to be connected to  a 
compatible modular jack that is also compliant. See  installation instructions for details.
Caution-to reduce the risk of fire, use only No.26 AWG or lager telecommunication cable. 
The USOC jack required RJ11-C, and the REN is used to determine the number of devices that 
may be connected to a telephone line. Excessive RENs on  a telephone line may result in the 
devices not ringing in response to an incoming call. In most but not all areas, the sum of RENs 
should not exceed five (5.0). To be certain of the number of devices that may be connected to a 
line, as determined by the total RENs, contact the local telephone company. For products approved 
after July 23, 2001, the REN for this product is part of the product identifier that has the format 
US:AAAEQ##TXXXX. The digits represented by ## are the REN without a decimal point  
(e.g., 03 is a REN of 0.3). For earlier products, the REN is separately shown on the  label.
If this equipment TDW-33 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, operations or procedures that 
could affect the operation of the equipment. If this  happens the telephone company will provide 
advance notice in order for you to make necessary modifications to maintain uninterrupted ser vice.
