I have a BLN2 part# 71000 in stock refurb with 90 day warranty. We also have all the necessary cards for testing and booting the chassis. Call me at 727-527-0227, or on my cell phone at 727-415-1371. We also have a large quantity of the AC Power supplies for these chassis’.

Hi Violeta,

You could probably look for a BLN (smaller chassis than a full sized BCN) since I believe they had inter-changeable power supplies.

Unfortunately, I salvaged my last BCN/BLN about 16 months ago now. Sorry!

Cheers!

I was reading your blog on the backbone concentration nodes you have/had and I was wondering if you could help me out. I’ve been trying to find one to buy for a while now, and I can’t seem to find a used one anywhere. I work in a repair center for electronics equipment and I get a lot of the power supplies in for repair. We can repair the power supplies here but I don’t have a way of testing them to make sure they work properly.
Do you know of a place that I could get one at a decent price at? Would you be interested in selling one of yours :)

Thank You,

Hi Tommy,

I don’t exactly remember myself right now… is the cover off the front of the chassis? If so you might try placing the cover on the chassis.

Good Luck!

After i power up the 73000 with SRML i notice that the led infront of the chassis show power lighted green Run light green Boot lighted Green Diag lighted Orange. Do you know what are the normal operation LED status?

Cheers
Tommy

Thanks for your advise. :)

Hi Tommy,

It’s just a standard serial cable, 9pin to 25pin. I can’t remember right now if it’s a straight-thru (modem cable) or if there is a null modem (cross the Tx and Rx pairs). I would probably try a modem cable first, probably something most of us have lying around somewhere.

Good Luck!

Recently i was trying work with 73000 but notice that the console was 25pin. Do you know what is the console cable 25pinout?

Cheers
Tommy

Hi Don,

There was a custom image/software builder that allowed you to strip various components out of the software build. If the software is straight from Nortel then it should support the FRE2 processor. It was the ARE and FRE4 processors that you might need a specific version of software.

Good Luck!

Hi Bruce,

I believe the only port you need open is SNMP (UDP/161). If you check your firewall logs you should be able to see which ports the client is trying to connect to.

Good Luck!

Thanks for the comment Bruno!

We’re migrating the remaining T1 circuits to an Internet VPN solution based on Juniper’s SRX product. Thankfully there’s broadband Internet available from the local cable TV provider at all our locations.

Cheers!

Yeah man, I do manage a lot of those old gear in a DCN Network of a Telecom in LATAM (They form an E1 network with a huge span over three countries):

06 x BCNs
04 x BLN
80 x ARNs

They’re really plain network gear. No real tricks, except for the site manager, which of course is realy bad when you’re used to CLIs. Since we run both IP and OSI protocols (for old SDH management) and it’s support for OSI configuration via CLI is NONE, this makes the CLI fanbase (which includes me) cry out loud when site manager is a mandatory tool.
About hardware stability, they run pretty cool here. Once in a year or less we have some kind of issues in a E1 card (mainly in the ARNs, the FE1 – fractional E1 – cards) but we had an BCN running for 3 years in a roll without problems (We had to move it to another datacenter, but I guess that it would take more 5 years of punishiment!).

By the way, we’re trying to get rid of it because spares can be a hell in LATAM… Replacing those huge BCNs for smooth, quiet and short Cisco’s 2821/2811 will be hard, but besides missing it, we’ll get over it! hehehehe! :)

Hi Chris,

We’ll keep you in mind if we decide to sell any gear. With respect to testing the cards, it’s pretty easy. Just put the cards in any working chassis and the card will run through a POST sequence where it performs all sorts of tests. If the card boots up and passes the POST test sequence you should be good to go. I’ve never seen a specific port die but I’m sure it’s possible.

Good Luck!

Hi John,

You’ve brought back some really ugly memories of DSQMS. I don’t think I’m going to be able to sleep all night now after recalling all the nightmares trying to get Bay’s support folks to provide adequate documentation on DSQMS. That was the very very early days of IP telephony with the purple barney i2004 phones.

Thanks for the comment!

Yes, those were the days… we probably had about about 7 BCNs with HSSI DS-3 interfaces and around 30 AN/ARN/ASN routers with a lot of T1 PtP and Fractional (512Kbps) T1 Frame Relay.

We had access to the corporate software suite so we never had to worry about the feature sets. Although we originally ran ATM on the BCNs which were connected to our ATM LAN of Centillion 100 switches.

Look how fast technology has progressed in only 10 years.

I also at one time had several ASN routers. Oh, those were the days – IPX, BOT (Bisync over TCP), DLSw, SDLC – protocols I used to use with these routers (and I had to buy the full routing license to get BOT originally – remember the three Nortel routing license levels), but along with 208 BSC modems, no longer used – YEA!

one thing typical NT has failed big time to convert something’s good (yea, call me crazy) to a bigger opportunity.
how i miss those MIB browsers!
