Description: The Quantum Bridge VT connection table contains a list of VT1.5 connections that are provisioned at OAS SONET(STS-3) and SDH(STM-1) interfaces between IOT(DS1/E1) ports and VTs/VCs, ATM PVCs and VTs/VCs, VTs/VCs and VTs/VCs ports. The STS-3 interfaces are listed in the sonetMediumTable(RFC2558) as interfaces with the 'sonetMediumType' object set to sonet(1) value. The STM-1 interfaces are listed in the sonetMediumTable(RFC2558) as interfaces with the 'sonetMediumType' object set to sdh(1). The table has 2 indexes of the first end-point: Sonet interface index, vt/vc identifier. Note: All connections between ATM ports and VTs/VCs are listed in the atmVclTable.
