Once released, BNP binds to and activates the atrial natriuretic factor receptor NPRA, and to a lesser extent NPRB, in a fashion similar to atrial natriuretic peptide (ANP) but with 10-fold lower affinity.
The GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.The GTP-C enables several procedures to be performed through the GPRS backbone network, including path management, tunnel management, location management, and mobility management.he GTP layer for the control plane (GTP-C) tunnels signaling messages between GSNs in the GPRS backbone network.
In a VoIP network, call signaling is one of three major categories of communications traffic, the other two being call control and media communications. Call signaling is used in voice over IP (VoIP) systems to establish connections between H.323 endpoints, or between an endpoint and a gatekeeper.all signaling is used in voice over IP (VoIP) systems to establish connections between H.323 endpoints, or between an endpoint and a gatekeeper.
