UNI or NNI?

  • From: Jane Ferreira Cunha <jane@telesc.com.br>

	Hi, folks!

	Basic question from a newbie.

	I have a Centillion switch with both ATM and Ethernet cards. This
 Centillion is connected to our ATM network, and we have servers connected
 to the Centillion through both ATM and Ethernet interfaces.
	My question is:

	1. What is the type of the connection between the Centillion and
 the ATM network, UNI or NNI? I mean, if I have already a UNI connection
 between the server (with ATM card) and the Centillion, can I have another
 UNi interface between the Centillion and the ATM network?
	If I configure a NNI interface between the Centillion and the
 ATM network, what happens to the servers connected through an Ethernet
 interface, will it be possible for them to access other machines through
 the ATM network?

	I hope I made my problem clear, but if I didn't, please tell me.

		I'd appreciate any help.

				Jane.
