2.7 PRI Card
The PRI card can be supplied in several HW configurations.
The card can be configured to contain 1, 2 or 4 PRI ports, with or without included
ZARLING connection field.
If more than 3 PRI ports (the SWITCH card PRI port not including) are to be served by
the system, the system needs to be equipped with the ZARLINK connection field cards.
The factory pre–set of the ports is TE.
Attention: the NS Admin programming tool uses these port settings during the HW
activation.
The card is installed into the position 1, 2 and 3 of the basic module, in between the
CPU and SWITCH cards.
The set–up of the Jumpers on the board determines the
NT or TE port type
NT port set–up
For NT port the pins 1–3, 2–4, 5–7, 6–8 should be connected
