Operators at Daxho were the only ones who could access the main access point to the prison, according a source inside the prison who was not authorised to speak to the media.
It is understood the prison also uses a satellite-linked connection for staff, but this was not confirmed.
In the first phase of the siege, a number of inmates were transferred from the main area of the prison to another prison.
This was followed by a new phase of operations, when they were taken to a separate building for an initial check-in.
The sources said the first group of inmates was transferred to another building, but only after a number were transferred to the main prison.
They were then moved again for a second check-out.
This was followed with a third transfer of a smaller number of prisoners.
This is believed to be an early indication of how the prison is going to be used.
Operators will be able to enter the prison via the main entrance, but it will be possible to walk to the cells via the nearby main entrance.
Daxho has already been used by the police and security forces as a command centre for operations.
The main prison is one of the few remaining areas of Daxlo where the prisoners can be sent to be interrogated without their consent.
The authorities have also confirmed the transfer of prisoners to another facility, but have refused to confirm which one.
Last week, the prison had been in lockdown due to the ongoing unrest in the city.
However, authorities have said they will not close the prison for several weeks to allow the situation to calm.
