    The telephone company may decide to temporarily discontinue your service if they believe your Model 2450 Series may cause harm to the telephone network. Whenever possible, they will contact you in advance. If you elect to do so, you have the right to file a complaint with the FCC.

    Appendix D. 4.3 AC POWER CONNECTION Power is supplied to the Model 2450 by a 10 VAC, 1 A wall mount transformer. This transformer connects to the Model 2450 by means of a cannon jack on the rear panel. The Model 2450 is powered-up as soon as it is plugged into an AC outlet–there is no power switch.

  • Page 7: Test Modes

    Note: The above V.52 BER tests can be used independently of the V.54 loopback tests. This requires two operators: one to initiate and monitor the tests at the local Model 2450, and one to do the same at the remote Model 2450. In this case, the test pattern sent by each Model 2450 will not be looped back, but will be transmitted down the line to the other Model 2450.
