New provisions for analogue circuits meeting either of the following criteria are now automatically provided as Analogue over Digital (AoD) circuits:
- All analogue circuits of over 15km radial distance.
- All four-wire analogue circuits (including analogue network) that include a main link.
Own exchange circuits (baseband) do not fall into this category.
The above criteria only applies to new supply or upgraded analogue circuits or circuits requiring engineering rearranges. All other sub 15km analogue private circuits should be provided in the traditional manner.
This option is not available on request.
