Eight PRT(1)-U( ) ETUs can be installed in a system.

Up to 64 ISDN trunks (B Channels) can be assigned in a system.

The PRT(1)-U( ) ETU can be installed in any slot (1-8) in any cabinet (1-3), except when more than 24 channels are assigned in which case a free slot is required to be left to the right of the slot containing the PRT card.

Common

Each PRT(1)-U( ) ETU supports the connection of one Primary Rate ISDN line, complying to the European ETSI standard (Australian standard ACA TS038).

Memory Block 1-1-80 (ISDN 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 red LED is On, and the following error message is displayed on the first line of the LCD of Multiline Terminals connected to port 1:

zLayer 1 Down: COxx Layer1 DOWN

zLayer 2 Down: COxx Layer2 DOWN

zxx is the CO Trunk Number (01~64)

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

For the Australian Network only, Malicious Call Trace is possible on MLT. This service can only operate when the class of service is assigned and is subscribed with the Telstra Network.

The subscription to Malicious Call Trace (MCT) is per interface. That is, to have MCT for more than one PRT(1)-U( ) ETU in a system, all are required to be subscribed.

PRI firmware version 2.12 or higher, access to network supplementary services is possible via the stimulus (Keypad) mode of operation

The CLKG-U( ) Unit must be fitted onto the CPUI-U( ) ETU when the PRT(1)-U( ) ETU is installed. The clock unit is a Phase Locked Oscillator which automatically synchronises the Xen IPK system with the ISDN Network. If a BRT(4)-( ) ETU is also installed in the system, the synchronisation can be provided from either interface. Switch SW1 on the CLKG-U( ) Unit must be set to the ISDN-PHS setting.

The PRT(1)-U( ) ETU supports DTMF signalling during the conversation phase of the call.
