All involved media gateway must be equipped with MGU boards.
Limitations in the system
Seamless Hand over
In order to secure cordless phone functionality, the MX-ONE system
must be synchronized to the reference timing source
Synchronization between all ELU31 boards in the system are handled by
a ring structure. The ring consists of two separate electrical interfaces for
synchronization. This to get the DECT air frame synchronization
correct.
The number of ELU31 boards connected to the ring are different for
different media gateway types.
•
MX-ONE Classic (LBP22 with MGU) max 1 ring member
•
MX-ONE Lite (LBP24 with MGU) max 1 ring member
For a more detailed description regarding synchronization and synchro-
nization ring cable, see installation instructions for CORDLESS PHONE.
Also, if one of the parties in a call is registered on an EMG Media
Gateway, seamless external hand over is not possible. (External hand
over is possible, but not seamless).
Note: Even if only one ELU31 board is used in the ring there has to be
ring cable looped between Tx and Rx on that ELU31 board.
ELU31 Boards
The practical limitation of the number of ELU31 boards in a system is
decided by the number of portables, how much traffic each portable
generates, the Grade of Service (GOS) that is accepted by the customer
and the power consumption.
When using MX-ONE Classic with MGU, the practical and power limita-
tion is 10 ELU31 boards.
When using MX-ONE Media Gateway Classic with LSU-E, the practical
and power limit is 5 ELU31 boards per (DSU-controlled) subracks, or 15
