[nsp] Cisco ONS 15454 CTC 3.4 provisioning problem with T1s

Hi Tom,
    Ask your provider if they are doing VT/STS muxing or M13 muxing.  Most
providers do M13 muxing, which just appears as a DS-3 to the 15454.  You
need VT/STS muxing to do what you want to do.  For them to do VT muxing,
they will need to come off their DACS with an STS payload, not a DS-3.  If
they are handing you a DS-3, you need to get them to change to a VT muxed
STS or you will need a second shelf with a transmux card (XM), which is
where your DS1-14 cards will go.  You will need a straight DS-3 card in your
high speed (top) shelf.  If you have enough slots, you can actually do the
tributary function in one shelf, but you have to come out of the back of the
electrical interface panel with your DS-3  and back in to the DS-3 transmux.
