I’m wondering what options there are for supporting T1 access methods under current versions of ROS. According to the Wiki, after ROS 3.15 only Farsite cards are supported as PCI T1/SYNC serial cards… but they are incredibly expensive at $1000 per port!
Has anyone found any other supported options? I’m primarily interested in interfaces that would support PPP (or maybe HDLC?) T1 circuits.
The idea here is so that I can buy a point to point circuit from my NOC to a customer, and plug it in to my Mikrotik core router.
Craig, have your Mfg guys just emulate a cell modem interface - they are going faster than 1.5mbps now anyhow, and if they did that then it wouldnt look any different than the other cell modems out there already working. They use PPP as well.
Yes but the point is, you position your product as a viable core router product - yet you don’t support a resonable set of WAN interface cards. To be a real core router product you need to support:
I know it might be hard to find supportable OC3 hardware, but there are PLENTY of DS3/T1 PCI cards out there, for example:
Digium: PCI & PCI Express cards that support T1/E1 PRI, PPP, HDLC, and Frame Relay available in 1, 2, and 4 port versions.
Sangoma: PCI & PCI Express 1, 2, and 4 port T1/E1/J1 cards & BRI cards supporting PRI, ATM, Frame Relay, X.25, HDLC, and PPP (among other voice-only protocols).
Both of these vendors run about $500/port at densities up to 4 ports/card - a lot better than the FarSite you support which is only available with integrated CSU/DSU in a one port card for over $1000. Their multi-port cards all require external DSU’s.
I have been wondering lately if the want to be at the core?? / edge (upstreem side)…
They seem to be leaning down stream… IE: small isp ===> CPE…
They dont seem to want the larger ISP core or at the edge between the IPS and the WISP…
They REALY dont seem to want the corporate environment in the US… We ALL use Ts or some form ot it IT T1, bound T1s ot T3s to our data centers from out ISPs…
I cant speak for them…
Just what it looks like from here…
I have been told of T1 to 100T converters for YEARS but have never been given a link to one let alone where I can get one !! I still think it is vaporware..
My 2c, Over this side of the planet no one uses T1/E1 for ISP connectivity, they are considered legacy. All the Telco’s I know of have moved to ethernet/mpls backbones and offer ethernet connectivity to their wholesale customers such as ISP’s. Mikrotik’s products fit our ethernet based networks extremely well.
Well I guess we are still in the stone age here in Tempe AZ (Poenix)..
I have over 36 fiber pairs here and 100 copper pairs from the local telcos here in my data center from three different telco “mains”.. in the Phoenix,Chandler,Tempe area…
(We are in an old Verizon building)… the Fiber is terminated into a Fujutsu rack and drops a T3.. (one pair)
THe rest of the data com and voice is from copper T1s.. That is what the telco would drop.. (and they were a PAIN got get stable (3 MONTHS !!!) Thanks QWEST)
I cant get them to light the fiber lines that are there !! If they can light them, they want to drop it back to Ts…
It is the same all over the valley !!
From what I see… it is the same in the states !! you can get ethernet handoffs in some places, but bend over !!
In some places IE Chicago… ( was working with a telco on a solution) multiple T1s are MUCH cheaper than a fract T3.. The loop charges kill you !! we were working on a 12 T1 bundle solution..
Our cable infrastructure is older here… and the Telcos think like Telcos not ISPs..
We colod our phone switch and some of my equipment for about a year in one of the local telco’s cages recently they ran Ts into the cage, not Ethernet, Ts…
