The input & output ports of the TWOx12 system.
Note that the system can easily be expanded to support up to four Desktop Directors™; Only one
of the input options (AES/EBU or Analog) can be selected at a given time; POTS TWOx12
systems substitute 12 analog POTS circuits for the ISDN circuits shown above.
Identifying your TWOx12 system – Analog or Digital?
You will need to identify whether your system is a POTS (Plain Old Telephone Service -
analog) or an ISDN version, since we will cover them separately in the following
instructions. If you are installing a mixed system you should read through both sets of
instructions. Towards the end of this section (section 2.5.4) we will specifically address
mixed POTS/ISDN systems.
