Hi to all!

We have a strange problem as below:
We use pairs of G.SHDSL back to back modems for extending ethernet cable through one copper pair to conncect remote ethernet equipments to one local ethernet switch.
There are about 60 G.SHDSL links which comes to PSTN and then come in our premises through one cable with 100 copper pairs 0.5 mm.
There are situation when three to four links goes down at the same time of the day or when their link quality decrease.
Is there any way how to avoid this situation?
Is there any ratio which we have to consider as % between used/unused pairs in the cable?
Thank You in advance
