Common

ISDN Trunk DTMF Duration/Interdigit Selection is effective after Answer Supervision is received from the CO.

When an ISDN line Layer 1 or Layer 2 down condition occurs, the CO line key LED turns solid red, and the following message is displayed on the first line of the LCD of the Multiline Terminals connected to Port 01:

Layer 1 Down: COXX Layer1 DOWN

Layer 2 Down: COXX Layer2 DOWN

XX represents the CO Trunk number (01~64).

Layer 1 down display has a higher priority than Layer 2 down. This error display disappears automatically when Layer 1/Layer 2 error is recovered.

The Xen IPK system supports BRI ISDN lines conforming to the ETSI standard.

The BRT(4)-U( ) ETU supports the T-interface, but not the U- interface.
