csp Signalling Transport Mode

1.3.6.1.4.1.9.9.126.1.7.1.1.3

This object represents the mode used to transport DS0 Signalling information for T1 byteSynchronous mapping (GR253). In signallingTransferMode(2), the robbed-bit signalling is transferred to the VT header. In clearMode(3), only the framing bit is transferred to the VT header. The initial value is signallingTransferMode(2) if csTributaryMappingType is byteSynchronous. For asynchronous mapping, it is notApplicable(1). The value notApplicable(1) can not be set. ::= { cspConfigEntry 3 } SYNTAX INTEGER { notApplicable(1), au3Grouping(2), au4Grouping(3) } MAX-ACCESS read-write STATUS current DESCRIPTION This object represents the method used to group VCs into an STM-1 signal. Applicable only to SDH. au3Grouping: STM1<-AU-3<-TUG-2<-TU-12<-VC12 or STM1<-AU-3<-TUG-2<-TU-11<-VC11. au4Grouping: STM1<-AU-4<-TUG-3<-TUG-2<-TU-12<-VC12 or STM1<-AU-4<-TUG-3<-TUG-2<-TU-11<-VC11. The initial value is au3Grouping(2) for SDH and notApplicable(1) for SONET.
