Supported CLI Signalling

Hi Guys,
Could someone tell me what type of CLI Signalling the OXO supports. e.g. FSK/DTMF.

The CLI (Calling Line Identification) feature for APA (Analog Public Access) and AMIX/AMIX-1
(Analog Mixed Line) boards allows the caller number to be received through the analog
switched public network.
This feature is based on the CLIP (Calling Line Identification Presentation) additional service;
the CLIP information is transmitted via FSK (Frequency Shift Keying) asynchronous signals in
on-hook mode (during ringing).
The FSK signal can be detected in two different ways: centrally at the CPU level or locally via
the APA board (CLIDSP daughter board).
The central detection at the CPU board level is not available in the USA (local detection only
via CLIDSP daughter board on APA).
