Appendix B
7-6
To listen to, or to record, the voice signals on the channel monitored, two telephone sets, or two recording
devices, are needed, one attached to Channel 3 or PORT K for the local signal, and another attached to
Channel 4 of PORT K for the distant signal. Of course, in the case where only one telephone or one
recording device is used, signals of the two directions must be combined. See sales representative for a
combiner.
This channel bank application, including monitoring, has been tested. If you have any questions, please feel
free to contact your sales representative.
