VS1 Installation, Configuration & Operating Guide

To calculate the proper Disconnect Signal setting for the system, first discard any values that are
less than 450 mS. Select the smallest remaining value, subtract 20 mS from that value, and then
divide the difference by 10. Use this value as the new Disconnect Signal.
For example, if the following Disconnect Signal values were recorded:
CO :Flash 800 mS[1]
CO :Flash 820 mS[1]
CO :Flash 750 mS[1]
CO :Flash 325 mS[1]
CO :Flash 950 mS[1]
Discard values less than 450 mS. Subtract 20 mS from the smallest remaining value, which is 750
mS. Divide the resulting difference, 730 mS, by 10. The correct Disconnect Signal setting for this
system is 73.
Note
If none of the recorded values are greater than 400 mS, disconnect supervision is not
being provided. Contact the local telephone company and request that COD service be
added to the lines.
