Each subscriber point in an AlphaCom exchange has a physical number. The number is determined by the board position and the type of module (master/slave). The number series 101 to 499 and 5000 to 5152 are default directory numbers for all AlphaCom exchanges. The directory numbers are connected to physical numbers in the range from 1 to 552, where the physical numbers are given by the subscriber point on a board in a certain position in a defined module.
AlphaCom E20 and 80+
Since the card positions 2 - 7 are not used in AlphaCom E20 (and 80+), the physical numbers 7 to 43 and the corresponding default directory numbers are missing. The directory numbers can be changed by using the AlphaPro programming tool.
IP Stations
IP stations must also be given physical numbers in the range of 1 to 552. This number can be any number below 552, but must not overlap star wired station physical numbers.
It is recommended to start the numbering of IP stations from 552 and downwards to avoid occupied number problems if the exchange is extended with more star wired stations later on. In single module AlphaCom E7 the IP Station can start on physical number 37.
VoIP channels
The physical numbers 605 to 634 are logical numbers inside the AlphaCom E, reserved for VoIP channels used by AlphaNet and SIP.
AE1 timeslots
The physical numbers 553 to 604 are reserved for timeslots 7 to 32 when AE1 boards are used.
