15 new services between numbers 1 and 200 have been introduced
under BSEP since Nov 2012 - namely 4, 20, 41, 47, 49, 50, 102, 116,
117, 118, 120, 121, 122, 140, 141.
This leaves 21 empty slots 1, 44, 46, 68, 71, 104, 108, 110,
114, 126, 127, 129, 134, 137, 144, 146, 148, 149, 150, 152, 164. At
this rate of introduction, we can expect 1-200 to be filled by
latest 2020, before a new numbering series (such as 4xx) becomes
the norm for new services.
