The error message appears on any attempt to change the timeslot map in
unframed mode:

Invalid option for unframed mode
:
3.4.5.1 Timeslot 0
The timeslot 0 usually is not included in a list of transmitted timeslots since
it is used for framing synchronization and carries no payload data, but its
transmission demands another 64 kbps of the DSL rate.
If the timeslot 0 is used to transmit payload data in additional (service) bit
positions, it may also be included in the list of transmitted timeslots:
: e1a map add 0
E1A: Long-Haul FRAMED Code=HDB3 – ONLINE
