Series connection of extension telephone(s)
Any other usage will invalidate the approval of the facsimile if as a result it then ceases to comply with the standards against which approval was granted.
Series connection
When connected via series apparatus, difficulties may occasionally be experienced when making calls to the PSTN and by both parties during telephone conversations. If difficulties are experienced, contact the supplier or maintainer of the series apparatus in the first instance.
While operation may be possible initially, changes to or modernisation of the network taking place in the normal course of events may result in the facsimile equipment being connected to a network service with which it was not designed to be compatible. Failure of the facsimile / series apparatus to work under these circumstances may not be the fault of the network operator.
The voltage drop introduced by your facsimile between the PSTN and the associated apparatus at a current of 40mA d.c. is 2 volts, therefore no additional series equipment may be connected.
