Limitations
BusinessPhone 50
Due to the limited number of available board positions with BusinessPhone 50 (5 slots) and backplane restrictions,
only the IC-CU2 board is allowed to be installed. IC-CU or IC-LU boards will not be supported !
Traffic limitations
An IC-LU can provide up to eight base stations with a maximum of eight PCM channels. One base station can handle
up to 8 speech channels. They can be connected to the PCM channels on the IC-LU. All base stations connected on
the same IC-LU have to share the PCM channels. This can lead to a busy group because of Cordless traffic
congestion. It is possible to use additional IC-LU boards to expand the PCM channel of an overloaded IC-LU. They
can share their PCM resources to be able to regulate traffic peaks.
Programming
Operation and maintanance (O&M)
Even though the cordless system is logically integrated, there are two different systems concerning installation and
O&M. Both systems have to be configured and maintained seperatly.
• BusinessPhone 250 via RASC via V.24 interface on CPU_ , AUX_ or via V.22 modem on CPU-D4.
• BusinessPhone Cordless via Cordless System Manager SW via V.24 interface on IC-CU_, CPU-D4 or
via V.22 modem on CPU-D4.
The portable telephone numbers stored in the IC-CU_ and in the CPU_ board have to correspond to each other:
e.g.: Number in RASC Number in DCT
(command: 5630)
Master: 216
Slave: 234 216
Important note:
Be sure to always create/change/delete the Slave directory number in RASC AND in the Cordless System Manager,
especially when reconfiguring ASB 150 02 !
