2.8 BRI Card
The BRI card services 8 fully functional BRI ports. The port configuration is TE
or NT, with PTP or MPT line interface support.
On the NT interface the power supply can be switched off – 42V.
The factory settings of the ports are as follows:
ports 0,2,4 and 6 preset as NT with power supply
ports 1,3,5 and 7 preset as TE
if you desire to use the BRI ports for the synchronisation, no line card position
may be skipped between this card and the SWITCH card.
The card is installed into the basic module on the line card position.
Attention:
the NS Admin programming tool uses these port settings during the
HW activation..
The set–up of the Jumpers on the board determines the
NT or TE port type
