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 – 42 V.

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.
