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.

(ii)Problems in telephone conversion being experi enced by both parties to the call
(iii)Such that any apparatus which forms part of the RBS or is connected via it, is so connected that no signals of any kind may be conveyed between that apparatus and a PSTN circuit or

TEL/FAX Change Over
When the OKIFAX 4100 is in changeover mode, care must be taken to ensure that you only connect the apparatus to tele- phone lines not listed in the telephone directories issued by the Public Telephone Network Operators.
The telephone number of this apparatus should not be issued to other parties without instructions concerning the correct method of making calls to this apparatus.
While operation may be possible initially, changes to or mod- ernisation of the network taking place in the normal course of events may result in the apparatus being connected to a net- work service with which it was not designed to be compati- ble. Failure of the apparatus to work under these circum- stances may not be the responsibility of the network operator.
If such difficulties are experienced, please consult your OKI- FAX supplier.
