Define if DSx service is structured or unstructured. A structured(3) interface is some nx64Kbps. (n x DS0 = n Time Slots) An unstructured (2) interface is full DSx, x >0. (1.544Mbps, 2.048Mbps, 6.312Mbps, 44.736 Mbps, or 34.368 Mbps.) This objects selects the connection type also for AAL1 Stream for Data port. The available selections depend on the data rate selected. For the 64 kbps rate: STRUCTURED WITH POINTER = structure(4) Use of the structured service as defined in ATMF AF-VTOA-0078.000. STRUCTURED WITHOUT POINTER : same as above, but without using a pointer (the resulting cell structure is similar to that of the unstructured service cells). Default: STRUCTURED WITH POINTER structuredControlSignalsTransport -Pointer is used to transfer Data Control Signals through ATM network. For other rates: STRUCTURED : Use of structured service as defined in ATMF AF-VTOA-0078.000. UNSTRUCTURED : Use of unstructured service as defined in ATMF document AF-VTOA-0078.000.
