Hopefully, one our European friends will have a better answer, but
my understanding was that in older (don't have a definition of older)
European telco you would find the batter stack with 60 V, rather than 48,
Then you had to worry about the charging voltage and step down power
supplies.
This could also be an old wives tale so I am also anxious to hear
this answer

Subject: Is 36-72VDC power supply input still valid?
I have recently had a discussion with someone who stated that people are no
longer specifying a 36-72V input, and that they are specifying 42-56V
because it is more standard for todays applications? Does anyone know where
the 36-72V input requirement originated and where and when we still need to
design to the old specification of 36-72V?
Any input would be greatly appreciated.
