3-96 Telephone Features
P 3.2 Telephone Features
Paralleled Telephone Connection
Any extension can be connected in parallel with a proprietary telephone and a single line
telephone. In the event of a power failure, CO1 and CO4 can be accessed using the single
line telephones that are connected in parallel with the proprietary telephones to jack
numbers 01 and 09 respectively. If the extension receives a call, ringing will be heard
from the proprietary telephone and the single line telephone. You can answer the call by
using either the proprietary telephone or the single line telephone. An answering
machine, facsimile, MODEM (personal computer), etc., can be connected instead of a
single line telephone.
System Programming is required to enable this feature.
