One Connection Set comprises one Retransmission Username (RTS ID) per subscribed OMD datafeed product (excluding complimentary feeds). As long as the bandwidth of the testing line is sufficient enough to support subscribed OMD datafeed products, a pair of testing lines can support multiple Connection Set.
For example, with one Connection Set for Securities market data, the ISV can get a maximum of three RTS IDs by subscribing for SS, SP and SF in OMD-C . On the other hand, with one Connection Set for Derivatives market data, a maximum of four RTS IDs could be obtained by subscribing for D-Lite, DS, DP and DF in OMD-D.
