Equivalencies
The following equivalencies do apply:
• XFCOT COT SHL is equivalent with XUT COT TRC
• XFCOT COT LOL is equivalent with XUT COT NTC.
The entries TRC and NTC will no longer be allowed for the Generic XFCOT.
When any disconnect supervision is configured (CLS = BAT, BTS) the Loop
Start Trunk of the Generic XFCOT will be marked as having disconnect
supervision and will therefore follow the same rules as a Ground Start Trunk.
There is no configuration involved for this operation.
When any disconnect supervision is configured (CLS = BAT, BTS) the Loop
Start Trunk will be released when the disconnect signal is received. This will
apply also in call states such as ringing, camp-on, DISA, and Meridian Mail.
