Another limitation for the number of base stations that can be connected to one ELU31 board is the traffic intensity. One base station can handle 8 simultaneous calls and one ELU31/1 can handle 16 simultaneous calls and one ELU31/2 or ELU31/3 can handle 32 simultaneous calls. This limitation for the number of base stations per ELU31 board is depending on the number of users in the area, traffic per user and grade of service.
Note Do not use ELU11/1, or TLU20 or TLU50/1 boards in LBP20 magazines with ELU31 boards. The communication between ELU31 boards will be disturbed if this combination is used. The solution is to use ELU29 instead of ELU11/1, TLU76/3 instead of TLU20 and TLU76/2 instead of TLU50/1.
