Requirements
Adding Modules to
Your System
When adding additional modules to a MERLIN MAGIX® Integrated System you must determine if the unit loads provided by the current power supply can support new modules you may be adding to the system. A unit load is a measure of power used to determine the electrical load that a component draws from a carrier's power supply.
General Rules on
Adding Modules
●
Never have more than two (2) 800 BRI
modules,
two (2) DS1 modules (100D or 100 DCD),
two (2) INA modules (100R), or more than
one (1) 100D/100 DCD, and one (1) 100R
module in a carrier.
●
A maximum of two MERLIN® Messaging
R2.5 modules can be installed per MERLIN MAGIX
Integrated System R2.2; however, only the first
module installed (left most slot in system) can
be programmed for voice messaging and/or delayed
announcement service. The second MERLIN Messaging
module installed can only be programmed for delayed
announcement service. Whether both MERLIN Messaging
modules can be installed in the same carrier depends
on how many other -5 volt modules are also installed
in that carrier.
●
Lastly, there can be any combination of the
following three -5 VDC modules per carrier,
but do not exceed three per carrier:
●
MERLIN MAGIX Integrated System processor
●
MERLIN Messaging module
●
DS1 module (with or without built-in CSU/DSU)
●
INA module
●
800 BRI module
If you exceed three -5 VDC modules in a single carrier, the system will fail to come online.
