54. Procedure Private Network or PSTN The voice channels were designed for communication among multiple offices of a single company As such the levels obtained from the various telephone instruments of that private Integration network will normally be consistent within a few dBs Under these conditions the input level adjustment procedure is based on a signal source speaker of a 1004 Hz tone at 0 dBm Where regulations allow the voice channels may connect directly or indirectly to the Public Switched Telephone Network PSTN presenting a different set of conditions Here the calls may originate from widely different sources with extreme variations in signal levels up to 20 dB Further the levels from calls within an office will often be different from the PSTN levels Therefore it is strongly recommended that voice channels be dedicated either for private network use or PSTN use but not both If the planned usage for a single voice channel is both private network and PSTN operation then one of the applications should be selected as the primary use and the voice channel aligned for that purpose The secondary application should be validated to determine if a compromise setting is required Equipment Required 1 Two MetroTel Voice Network Analyzers VNA 70A or equivalent capable of generating a 1004 Hz tone at 0 dBm and also capable of measuring a receive tone level in dBm units 2 One asynchronous ASCII Terminal e g one no
