DS3 encapsulated in OC3c?
All, I'm about to bring up a transatlantic 622M circuit, and am stuck with an annoying SDH/SONET problem. We use the Cisco 15454 SONET mux on our network, and although we'd ordered a SONET OC12 circuit, we've since been told that it'll actually be an SDH STM-4 circuit. This shouldn't be a problem, as the carrier can convert from SDH to SONET at their handoff, or we can convert from SDH to SONET on the way into the 15454. However, unfortunately both solutions leave us in the situation where the smallest SONET unit we can use is an STS-3c - and we need at least one DS3 circuit running over this. So, I'm stuck trying to carry a DS3 in an STS-3c carrier (or, another similar solution). Does anyone have any suggestions for a "cheap" box that will do this - without getting into buying a full SDH mux?
