DS3 cards

RouterOS General
1

I was looking around and saw that beginning 2.5, there was a driver problem with LMC DS3 cards. I am looking at the wanPCI-1T3, but I am open to any DS3 card. Have the driver problems been resolved?

2

I have one of the DS3 cards and V2.8xx sees it. and will “Start the card”
The card shows the correct LEDs when on “loopback” and in “open” mode .(IE a coax loop cable installed and clock set to internal)

I do not have a DS3 cir. to test data transfer at this time.
I asked for the driver to be reinstalled (had been removed) Jhon and the crew updated their drivers (SBE had not done it yet…) but the client that wanted DS-3 has not installed the service yet.

So I can say that the card is “SEEN” and seems to work but I can not swear to data transfer (Yet) (I may just buy another card and set them up in a "Null Cir. Config). I have a relationship and source for SBE / LMC product, so if the need is great enough I will do the nessisary testing and make the cards avail. at a low cost.

Can you provide any additional information regarding the DS3 cards? I thought LMC was out of business? Is there a new company that makes a DS3 card? Is there an OC3 card available?

Will MikroTik confirm they support a DS3 card?

Thanks,

Brad

I think the cards are continued by SBE, here the link to the DS3 PCI card:

Hope that helps…

Yah, I found that page as well, but thank you for posting it.

Hey Craig,

Will you check with your SBE/LMC source and see what price they can come up with for these cards?

Thanks,

Will Do..

I have spoken with SBE today.
I am waiting on pricing arangements.
I am also working on getting Eng. samples for Mikrotik to verify opperarions.

Having a rough number of people who want them would help me drive the cost down.

If you are interested in T3 cards please post a reply and provide a guess of how many you may use.

Thanks !!

I know of one or two ISPs aside from myself that are interested in these cards if they can be bought for a reasonable price. I know reasonable is a relative term, but let’s see what SBE can do before we indicate what we see as reasonable.

I know I could use four pretty much immediately.

Thanks,

Brad

I am very interested in picking up two so I can use some inexpensive 38GHz DMR units that have DS3 interface (and 45mbps full-duplex throughput!). Price would have to be down around the 1k USD range to make it worth using the cards instead of external Ethernet to DS3 converters.

Last week I tested one of these cards at the CO. Worked fine w/2.9beta7. Waiting for the fibre run to be finished to put in in production.

Paid $1900 for the card.

$1900.00 … ouch! Yes, the RAD DS3 to 10/100 convertors are half that.

Where did you buy the DS3 PCI cards? Were they the SBE brand?

Best,

Got the card at one of the SBE listed suppliers. Don’t remeber which one, but looked around and all the prices seemed to be about the same.

$1900 aint cheap. But with a new P4 + MT license + 4 port ethernet card and the total is about $3500 for a DS3 Router + Firewall + Bandwidth manager.

Would have paid every bit of $3500 for a used CISCO that would have done nothing for us except provided the DS3 interface.

Our DS3 is scheduled to go in this week. Once it’s in, I’ll order a second card for a backup machine.

No question what you have built is a better value and far more powerful than even the 7200 series Cisco. I know first hand after removing a 7204VXR and installing a MikroTik P4 3.2GHz and DS3 card.

Tests showed that while under typical midday traffic load with similar firewall rules the MikroTik router produced 10mb more throughput than the Cisco with a NPE-400 engine. The MikroTik was also configured with a couple hundred Simple Queues, so it’s fair to say the MikroTik was doing far more work than the Cisco and still outperformed the Cisco.

We have just installed a MikroTik with Intel GB fiber interfaces for another facility we just turned up. The box fly’s with PCI-X GB fiber cards and two Intel quad 1000MB PCI-X cards.

BTW, I still think $1900 is too much for the SBE DS3 card. I’m pretty sure I was quoted right at or just below $1500. Hit me offlist if you are interested in comparing reseller notes.

Best,

Brad
