Features and Services
China – Busy Tone Detection
The interaction with Intelligent Peripheral Equipment (IPE) trunks occurs
because Busy Tone Supervision (BTS) can be configured in conjunction with
any existing supervision type. For the EXUT, BTS can now be configured
with a supervision type of BST (both incoming and outgoing battery reversal)
and Polarity Insensitive (PIP). These supervision type’s call processing
methods are not changed, except that now the first type of supervision
received is the one acted upon.
