On the back of my cisco router, I see the following ports:

  • 4 LAN ports
  • ISDN S/T
  • ADSLoISDN
  • Console

Two really basic questions:

1) Is the ISDN S/T port like any other WAN ethernet port? (i.e. can I plug an ethernet cable from my existing cable modem into it? or do I need a different router?)

2) To configure the router, am I able to connect to it via a LAN port (like other routers) or do I have to connect via the Console port?

Thanks.

Knowing the model is the most important part of getting the help you need. –  mfinni Mar 21 '11 at 16:29

1) No, ISDN and Ethernet are totally different, even if the ports have the same size.

2) You don't even tell us the model of the device.

Depending on the model, Cisco's "console" port is most likely also not ethernet, it's a serial port you'll need an adapter to plug a serial cable into. –  DerfK Mar 21 '11 at 16:29
