3.5 Add-on modules for system expansions
The Hicom 108 has one slot for the TLA2 (analogue trunk) or STLS2 (S
o
) module.
The Hicom 112 has two slots (1 and 3) for system expansions.
The Hicom 118 has 4 slots for expanded system configurations. The modules can be inserted
in any of these slots. Refer to the relevant module descriptions for details of any restrictions.
Subsequent expansions carried out on the Hicom 118 should be installed following the new
equipping sequence for extension and trunk modules.
If slot 1 is assigned with an SLU8 (U
P0/E
extension) or an SLAS16 (a/b extensions), slot 2 is
deactivated.
The above table only shows the possible slots. It does not illustrate the maximum configuration
possible or authorization-related restrictions.
