HiPath 1150/1190
The table below shows the settings available for KS with optiPoint using U
P0/E MODULES
:
Table 2-7 optiPoint and KS telephones for HiPath1150/1190/1190R.
Limitations:
If an 8-port U
P0/E
module is installed, the system will not free up another U
P0/E
module in the
system. Both the HiPath 1150 and the HiPath 1190 allow a maximum of 8 U
P0/E
ports, resulting
in 16 optiPoint telephones (master + slave) + 8 KS telephones, for a total limit of 24 system
telephones. Therefore, only combinations of UP0/E modules are possible for a maximum of 8
ports.
2.5.3 Notes on HiPath 1150
If there are only 2 PCM highways in the HiPath 1150 and one module TME1 is used, we would
have 30 timeslots reserved and a further 2 timeslots reserved for the analog trunks, which
would mean fewer than 32 timeslots free for all the other extensions of the system. To avoid this
limitation, the solution was to use an additional highway based on the DSP control for slots 3
and 4.
