This object specifies the backward signal requesting information about the nature of the circuit used so far in the call path, specifically whether it includes a satellite link. This matters because satellite links introduce significant propagation delay that affects echo-suppression and signaling-timer requirements, so the answer to this request, sent via ccasFwdRSSatelLinkIncluded or ccasFwdRSSatelLinkNotIncluded, determines which timer profile the call should use going forward. On a long-haul international call routed partly via satellite, the far end would respond to this request with the satellite-link-included forward signal, prompting the gateway to apply longer echo-suppression timers for that call.
