But I'm literally 100% confident given your description, that you are perceiving it as people using "cell phones" to replace VoIP, and not realizing that it's standard VoIP softphones being deployed onto mobile computing devices that are often, but not required to be, cell phones.

We have cisco everything and I was told it was too expensive to have softphones on our cell, we instead must have a separate cell phone. I doubt that, but who knows.

And yet it wasn't too expensive to have Cisco... suspicious.

yep, agree!

@mary It depends on what you have, some Cisco Switches came with GBIC others (now in time) come with SPF.

And now SFP+

(SPF is sunscreen levels, SFP/SFP+ are the adapters.)

This type of cable Im refering to.

The point was that it is cheaper to buy pre-terminated fiber in the lengths needed instead of buying fiber and getting it terminated.

Not that does not apply universally. It does apply for most office buildings.

Where he is, I have random conversations with people who are like "Oh yeah, I trenched across town myself." Things you never hear here. There is actually a lot of self termination, lol.

In one of the companies that I worked, they have an "Initial Test" for any Engenier;

They ask you, Are you an Engenier?, then do a Patch cord, here are the tools, make 1 with B Standard.

That is the way to show that you are a good engenier... jajaja

In network almost every core device (routers, switches and servers) may be NTP Master or Server. It depends on network design who will be the NTP Master, for me is the device which is "closest" to Internet.

At what point is it worth having your own data center? I would think the cost of it wouldn't be worth it for most.

Your own, meaning you own the facility rather than colo? That one is pretty easy....

You would go to your own datacenter when the cost to get the features you need from colo exceeds the cost to build and maintain your own (this would likely happen at around 15-60% of filling a single colo location.) And your staffing needs will play into this, if the colo has 24x7 support, and you only need 16x6, you might lower your own cost that way.

This is assuming you don't need the flexibility of putting equipment in and out from time to time or using multiple sites for it, like colo easily allows.

Do the frequencies used self modulate within the router? What I'm wondering is if when setting up a dsl connection if it automatically defaults to a specific frequency or is it constantly switching.

DSL is the wired bit. Wifi is from the access point. And this will depend on the protocol chosen. 802.11 b for example requires thebfrequency be set.
