mscSigChanGwGatewayCapTable 1.3.6.1.4.1.562.36.2.1.115.15.302

This attribute indicates the SigChan component's capability to convert from one access signalling type to another. Access signalling protocols (protocols between a Passport and external switching equipment, for example a PBX) are grouped into protocol groups. Protocols within the same protocol group are considered completely compatible. This means that no extra processing is needed when a call originates from an ingress link using protocol A and terminates on an egress link using protocol B if protocols A and B belong to the same protocol group. The following protocol groups are defined: etsiQsigPG - ETSI QSIG protocol group containing ETSI QSIG protocol, mcdnFamilyPG - MCDN Family protocol group containing NIS, Meridian Customer Defined Network (MCDN) peer to peer, and MCDN User to Network (UNI) protocols, analogAndCasPG - Analog and CAS protocol group containing most of the analog and channel associated signalling protocols with steady state line signalling and DTMF register signalling, euroIsdnPG - EURO ISDN protocol group containing most of the European national ISDN protocols based on ETSI ISDN (ETSI-T) standard. For every of the protocols group this attribute indicates what is the level of protocol conversion support available on the SigChan component: noGw - no protocol conversion available for the protocol group, singleEndedGw - only full protocol conversion available for the protocol group (that is the SigChan component on the other side of the subnet does not have to get involved in the gateway processing), doubleEndedGw - only partial protocol conversion available for the protocol group (that is both SigChan components, ingress and egress, have to get involved in signalling conversion), singleOrDoubleEndedGw - both, full and partial protocol conversions available for the protocol group, nativePG - the protocol group is the native protocol group for the SigChan component.
