New DS1-14 Cross connects

[drmmcisco]

I have 2 nodes 56 miles apart in my far node I have a MRC with a OC12 input  in my other node I have DS312E  and DS1 14 cards

For my cross connects do i need specific DS3 cards in my node that has my DS1 14 cards in them  or do I make the circuit from my other node which lets me specify the DS3 pos and the VT 1-1 pos and then I can tell it to go to my 1-1 pos in my DS1 14 card  This is my first one in my 15454 system so I want to make sure I do it right?

Can you provide a high level diagram for your network, showing what you are trying to interconnect with at the far ends (qty, speed of interfaces, equipment).  

Far End Node (FEN):

MRC12 e/w OC12

Interfaces req'd??

Near End Node (NEN):

OC12?

DS1-14

DS3-12E

The DS1-12 card maps 12 DS-1s into a channelized STS1, which would be transported across the OC12 line. 

The DS3-12E card is typically used for a non-channelized DS3, which is transported over an unchannelized STS1.

If you need to drop a channelized DS3, say to an M1/3 multiplexer, then you can use a DS3XM-6 card (or a larger capacity card).  

More info would be helpful.

Thanx!

If the DS-1s at the Minot node are mapped into VTs (which you seem to indicate) and muxed into the OC12, then, at the Stanley node, you will be able to cross-connect them to the two DS1 cards (assuming the installed 15454 cross-connect cards have VT grooming support).

The description contained in the left-most MRC card in Minot node is confusing me.  Not clear on the statement "From Pos 6 DS3 of this card". 

Sorry for the confusion.

thanks for getting back  it is hard to understand someone else's setup  the minot MRC OC12 I get all my DS3's

from the company that this node is in this is my new DS3 for all of these 28 T-1's so they mapped it to the 6th POS of

that OC12 they feed me  which leaves me 6 more in the future.

I would assume that the DS3s (arriving on Minot MRC card) are M13 mapped to an STS-1.  If that is the case, then you would need a DS3XM-12 (transmux) card in the Stanley node to allow you to get the DS1s on the two DS1 cards. 

The DS3XM-12 card has port-less transmuxing capabilities, meaning it can accept an STS1/M13 DS3 (from the backplane side) and demux the DS1s to DS1s and map them into VT1.5s and then map the VTs into an STS1 for handoff back to the cross connect (XC) card; so that the VTs can be cross connected to the DS1 cards. 

This is the traffic flow.

Minot Node (MRC)DS3/STS1/OC12 -----> XC ----> (MRC)OC12 ----> fiber ----> Stanley Node (MRC)OC12 ----> XC ----> DS3XM-12 (accepts DS3/STS, converts to DS1/VT1.5s, maps to STS) ---> XC (grooms VTs) ----> DS1 cards (DS1 copper handoffs)

Clear as mud right?

Anyone from Cisco TAC on that could clarify/confirm my description? 

[drmmcisco]

thanks for helping me out with this   this makes sense  I will get one of those cards coming for my stanley node   the   

the diagram of traffic flow makes perfect sense

I had put into cisco a question report on this but have not heard form them  and the 3 new circuits I have waiting on me are getting impatient for there circuits

thanks again
