Re: [asterisk-users] ILEC Interconnect: Basic MUX: M13 vs DCS: VT1.5 vs DS3
If they will do atm over oc-n, perhaps that would work better. Ie, a perm virt circ for SS7 and as-needed vc's for ulaw. Atm oc-n cards with linux sw support are widely available, according to goog. libss7 and and ast *might* need a bit of patching to work with it, but it shoudn't take too much. Sip/rtp over private ptp ethernet is an option with at least some of the ILECs. They may call it virtual-pri or some such. Of course, if they are installing an actual sonet ring, and not just a spur, that can have built-in redundancy, depedning on physical routing. -JimC -- James Cloos cl...@jhcloos.com OpenPGP: 1024D/ED7DAEA6 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Hello Brian, Thank you so much On 6/12/13, Brian LaVallee b.laval...@globaltank.jp wrote: Hi Nick, Going from DS1 to OC-n is a multi-step process. Typically requiring a hardware device to handle each MUX step. But you can find hardware that handles multiple MUX steps together. The connection is coming into our premise on the OC-n transport. The question now is should we have it multiplexed as DS1 or VT1.5s to the DS3s. What is common today, I think DS1 VT1.5s mappings are more flexible? VT1.5 is just a raw OC-n channel containing a single DS1. An M13 device converts between DS3 and DS1. Understood!!! A DACS (DCS or DXC) provides M13 conversion, sometimes even capable of extracting the raw VT1.5 signal directly to DS1. The ILEC transport option you choose really depends on the terminating interface. Do you want to connect with a DS3 or OC-n? The transport is coming in as OC-n. What I am trying to figure out are the advantages of mapping the STS-1 using DS1s or VT1.5s. No matter what hardware you choose, you will need to convert to single copper pairs (DS1/T1) to connect to your Asterisk boxes. So an M13 or DCS will be necessary to reach the DS1 level. The device you choose depends on budget and growth expectations. Typically a DCS is an expensive investment, handling hundreds of DS3's. An M13 device is typically a small unit that handles one or two DS3's. This is almost understood. Is an M13 device basically a MUX (In our case STS-1-DS1)? From there we would plug the signaling into the Quad Digiums as you mentioned (this is where I get more comfortable). Could you kindly post a link to an entry level DCS with OC-n interfacing and M13s being used today. That way I can see what functionality each provides and determine which better suits our need. I am guessing, but hate to presume: M13: Adtran MX2800 DCS: Mediant 3000, Metaswitch 0610 etc.. The advantage comes when you add the 29th DS1. With VT1.5 it's just adding a single channel, DS3 will require another whole DS3 to get an additional DS1. This is why we are going SONET. It's a new transport layer for me compared to DS3s, and want to make sure I can put everything together at the network level. Sincerely, Brian LaVallee Thank you kindly, Nick from Montreal. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
