Point-to-Multipoint Connection with communication server
If a communication server is connected using point-to-multipoint, a direct dial
number must be created for each MSN number, with all the digits of the MSN
number.
NT1: Network Terminal
MSN: Multiple Subscriber Number
U/T: ISDN reference point
DSI: Digital terminal interface DSI
FXS: Analogue terminal interface FXS
Fig. 4 Basic access in point-to-multipoint configuration, with single-digit direct dial and parallel ter-
minal
Combinations are also possible in the case of several lines, e.g. one line in point-to-
multipoint configuration and the remaining in point-to-point configuration.
Note:
If terminals (e. g. MSN1) are connected in parallel on the BRI-T interface,
“Collision detection” has to be activated as the communication server and
the terminal influence each another. This also applies in cases where ana-
logue connections are used on NT1.
