Re: [Mikrotik] T3 interface cards
My apologies, I know this isn't a for sale list, but I have a LMC/SBEI T-3 card for sale. Gently used. Contact me off-list if interested. I'll forwarn you... our experience with it was great under 2.8 and 2.9, but it became unreliable under 3.x. Maybe they've upgraded the drivers since early 3.x came out and its better now, but that I don't know.

I got them from Brad Belton who said he used them for a while until he out grew them as well. Ended up selling them though because we downgraded to a fractional DS3 and the cards would not support it. Happily replaced with an Imagestream Rebel Router.

Re: [Mikrotik] T3 interface cards
Hi Butch, I've had two and only two folks reply that they used the LMC cards and had no problems, using 2.9x. What are the downsides that you've encountered? I know little about TDM, just enough to be 'dangerous'. I'm currently setup with a cisco 7000 series (not sure of the exact model) that basically just terminates our DS3 and forwards all traffic to mikrotik 2.9.51 core router. ATT is telling me the cisco is too small, even though they provided it, and I need to be employing some kind of caching. So, I am wondering if a decent mikrotik could handle those 'requirements'. Currently, cpu on the mikrotik runs ~30%, 2.4ghz intel box, with around 300 simple queues and 33meg of traffic running through it. I have 25 'tik boxes around the network and aside from some OSPF issues, never have any trouble with them. What would you or anyone else suggest I terminate the DS3 circuit into, if not a mikrotik?

Re: [Mikrotik] T3 interface cards
I would suggest ImageStream. It's a great combination of MT and Cisco - lots of capability, reasonable price and capable of lots of throughput. On ImageStream's website you'll find they compare their few models with Cisco alternatives.

Re: [Mikrotik] Mikrotik MPLS issue
Well, in the diagram, it's just a test network setup so that I get everything working in a controlled environment, then can replicate elsewhere. It's more universal than EoIP. A learning experience for when I need MPLS in the future. A marketing feature. If a customer sees that Global Crossing, AT&T, etc. provide their connectivity over an MPLS network, it certainly bodes well for me if I can say the same, even if it means nothing to your average user. It passes packets that are a full 1500 bytes. - Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -- From: "Butch Evans" Sent: Friday, December 19, 2008 12:33 AM To: "Mikrotik discussions" Subject: Re: [Mikrotik] Mikrotik MPLS issue On Tue, 2008-12-16 at 10:36 -0600, Mike Hammett wrote: One out of 5 routers I setup with MPLS doesn't respond to Winbox well after enabled.

To the best of my knowledge I followed the directions on the wiki. What is the reason you think MPLS is needed for such a network? MPLS offers absolutely NO benefit on such a small network. It is added overhead only. -- * Butch Evans * Professional Network Consultation* * http://www.butchevans.com/* Network Engineering * * http://www.wispa.org/ * WISPA Board Member * * http://blog.butchevans.com/ * Wired or Wireless Networks * ___ Mikrotik mailing list Mikrotik@mail.butchevans.com http://www.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS ___ Mikrotik mailing list Mikrotik@mail.butchevans.com http://www.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
