Interconnection Queues#

All ISOs support retrieving interconnection queues with iso.get_interconnection_queue methods.

Each of the ISOs report slightly differently fields for their queues, so a best effort was made to standardize column names. When a column couldn’t be standardized, it is appended to end of the returned dataframe.

Below you can see preview of each of ISOs interconnection queues
