INSTALLATION AND OPERATIONAL WARNINGS (Continued)
When the Model 748 will be connected to a PBX, the following statements apply:
The apparatus (Model 748) is approved for use as an extension instrument to
compatible PBXs. The supplier of the apparatus should be consulted for an up to date
list of PBXs with which the apparatus is compatible.
It cannot be guaranteed that the apparatus will operate correctly under all possible
conditions of connection to compatible PBXs. Any cases of difficulty should be
referred in the first instance to the supplier of the telephone apparatus. This apparatus
has been approved for the use of the following facilities:
MODEM
Auto-Answering
Auto-Clearing
Auto-Calling
DTMF Signaling
Any other usage will invalidate the approval of the apparatus if as a result it then
ceases to conform to the standards against which approval was granted.
This apparatus is suitable for connection to a PBX which returns a secondary proceed
indication.
Where the PBX extension wiring is not owned by BT, such connections may only be
made by the Designated Maintainer of the PBX unless:
1)
he has agreed in writing that another person may do so,
2)
he has failed to do so within a period of 14 days of receiving written
notice requesting such connection to be made,
or
3)
where the apparatus has not been approved as an entirety with the PBX
