Powering Additional Equipment
From Zenitel Wiki
Additional equipment often need power to be able to operate as intended. The source of such power varies depending on the type of exchange.
AlphaCom E7
If the additional equipment is located in close proximity to an AlphaCom E7 Exchange, the exchange can provide 24VDC from a dedicated output. If other kind of power is required, or if the additional equipment is mounted away from the exchange, a suiteable local power supply is needed.
AlphaCom E20
The AlphaCom E20 Exchange has an ouput which allows for connection of +5VDC, +15VDC and +24VDC. Each output is protected by a 1 Ampere fuse. Additional equipment that requires an external power source may use these outputs.
AlphaCom E26
When using additional equipment with an AlphaCom E26 Exchange, power can be distributed to the external equippment via the Power Distribution Board, PDB. The PDB board provides +5VDC, +15VDC, +24VDC and +32VDC from a number of outputs with several different connection types. The PDB board contains a 1 Ampere fuse for each voltage.
