Re: [c-nsp] Channelized DS3 over SM fiber handoff
If they are truely handing you a channelized OC3, then you'll need a channelized OC3 port adaptor - not the same thing as a normal OC3 adapter, at least for router interfaces. My guess is that the DS3 was extended with media converters, but the carrier didn't supply the near end media converter box as they should have. Whenever I've gotten an extended demark for DS3, either the carrier provided both media converters, or I had to extend the DS3 myself and I had to provide both media converters. There is no normal answer for this one - you really need to get the carrier to tell you what equipment is on the other end, and if you ordered a DS3 you need to insist that they hand you a pair of BNC connectors unless you've made some other special arrangement. -The Mickster On 5/1/09, Seth Mattinen se...@rollernet.us wrote: Troy Beisigl wrote: Maybe they delivered a channelized OC3?

Re: [c-nsp] Channelized DS3 over SM fiber handoff
I had a DS3 line from ISP that handed over by a fiber, but ISP provide a box convert fiber to 75ohm standard BNC cable to my router. (my router interface is clear DS3, not channelized) The converter came from Transition, don't remember the actual model, but something similar to http://www.transition.com/TransitionNetworks/Products2/Family.aspx?Name=SCSCF30xx-10x -- Michel~ On Sat, May 2, 2009 at 1:07 AM, Gert Doering g...@greenie.muc.de wrote: Hi, On Fri, May 01, 2009 at 11:12:35PM -0400, Ryan Werber wrote: Allstream at 151 front street in Toronto does this.

Re: [c-nsp] Channelized DS3 over SM fiber handoff
Guys! Thanks to everybody who replied on and off-list. Now I believe that telco will deliver channelized OC3, but I'll definitely have to reverify it with them. I'm sure I'll have more questions, but at this point I guess I have to get more info from telco. At least now I guess I have an idea what this is about.

Always a pair of 75-ohm coaxial cables on BNC connectors. Typically it comes in to the customer premise as a SONET fiber connection and a carrier-owned MUX and NID is installed with the customer handoff as co-ax. You would need to know the exact make and model of the hardware at the other end of the link to procure a compatible media converter if they are really terminating a DS-3 this way. And good luck when you have a case of trouble, the blame game on this one will not be fun. Are you sure they're finished with the provisioning and that there isn't another group scheduled to install equipment? -- Jay Hennigan - CCIE #7880 - Network Engineering - j...@impulse.net Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/

Re: [c-nsp] Channelized DS3 over SM fiber handoff
Allstream at 151 front street in Toronto does this. They run a single strand SMF and they terminate it into a form of a media converter, which passes off 2x BNC as expected for a DS3. They do this for both clear channel and channelized DS3. Interestingly enough, our channelized OC12s come in on a pair of SMF from them. I would imagine you would need a similar media converter - I'm sorry I don't have the model number of the equipment Allstream uses. All I know it is some sort of WDM equipment (obviously) on the fiber side.
