SONET Question

[rayroyaleverest]

Is SONET a WAN technology? If not, what WANT technologies does SONET function at?

Hi guys,

Sorry to stir it up again :-)

If you have two devices with OCx POS interface in each and you want to interconnect them, so you need a service provider in the middle that will give you SONET service using OCx, then you will connect it two both interfaces run IP on top, right?

This is in case you use service provider for long haul connectivity. What if you are building your own Core, do you still need service provider to interconnect your P devices in the same way (using OCx SONET), or can you run SONET by yourself?

Thanks,

David

Hi David,

You have different option which depends on how far are your office and how much core bandwidth you need, i am wiritng few option you have

1. Your offices are close by you can connect POS cards directly (you dont need SONET box). Like your7600 router have POS card of OC 48 (2.5 Gbps). Here you dont need SONET boxes. I think you can get distances till 40-50 Km.

2 If your office are far away but core bandwidth requirement is not more than OC-12/OC 48 then service provider is easy or you need SONET boxes which can regenerate your signal.

3. If your office are within 60-70Km but your core bandwidth requirement are more than Oc48 then either can take 10Gb ethernet card or Gigabit ethernet card.

4. If your core bandwidth requirement are high then you can take your 10G Ethernet/OC 48 POS over DWDM either from service provider or your own.

Hope it is clear.
