Parameter

Description
Block size The number of Directory Numbers in this Business Group Number Block. Note that the number block must correspond to a continuous range of free numbers in one of the NE's configured Number Ranges, so you need to select a block size that will fit within an unused section of a Number Range.
First Directory number The first directory number in this Business Group Number Block. Click on the ellipsis symbol at the end of the field to select this number, as follows.
  • Select a Number Range from those configured for the NE.
  • Select a boundary (10, 50, 100, 500, or 1000) to determine how the starting number in the range should be allocated, or select None if any starting number is acceptable.
  • Select Manual or Automatic block selection.
If you select Automatic, the NE allocates a block of numbers that meets your requirements for block size and starting boundary. It also indicates the continuous range of unallocated numbers around this block, to help you determine how much the available numbers in the range will be fragmented by your selection. If necessary, you can go back and specify a different block size, number range and/or boundary. If you select Manual, the NE displays a list of all possible number blocks meeting your requirements that could be allocated, again showing the range of unallocated numbers around each one. Select an appropriate block from the list, or go back and specify a different block size, number range and/or boundary if necessary.
