Point-to-point or point-to-multipoint connection
● Point-to-multipoint connection
HiPath 3750/HiPath 3700 can be operated on an ISDN multi-device connection (S
0
bus) to
CO. This allows parallel operation to other ISDN devices located on this port.
Note the following:
– Maintain the correct polarity on the T/R wires.
– The phone company assigns an 11-digit DID number (MSN or multiple subscriber
number) for telephones to be connected to the S
0
bus. There are usually at least three
MSNs per basic rate access.
– When setting the system-wide ISDN parameters, select "EURO CO PMP" under Port
configuration (code 20 4 1) for the port you are using.
– Enter the MSN in the table for DID numbers. For each MSN assigned, callers can di-
rectly dial a station, group, or hunt group in the HiPath 3750 and HiPath 3700 system.
– Leave the "PABX number" parameter unchanged.
– Always configure HiPath 3750 and HiPath 3700 as the last station on the S
0
bus be-
cause terminating resistors (2 x 100 Ω) are permanently installed in the trunk connec-
tion of the communications server. Remove any terminating resistors from the last
socket.
● Point-to-point connection
Use a point-to-point connection if you have a dedicated line (trunk circuit/tie trunk circuit)
or to extend the range if only one telephone is connected to the S
0
bus.
