Series Connection
NOTE 1
The OKIFAX 4500 causes a voltage drop of 1.35V when passing a
PSTN current up to and including 40mA dc. Do not connect the
OKIFAX 4500 with apparatus which, with associated wiring causes
the aggregate of the voltage drops to exceed a value of 2V at a PSTN
line current of 40mA dc.
The 2V level indicates the maximum impairment that may be
introduced between the terminal apparatus and the Network Terminal
Point (NTP) of a Relevant Branch system (RBS) containing the
apparatus.
