The following hardware is required to run the vmsamp_ip324m_bicc application:
CG 6565 board for bearer processing: RTP packetization, NbUP framing protocol, H223 Multiplexer. The CG Ethernet interface is used to send and receive User Plane traffic.
TX 4000 board for BICC over SIGTRAN signaling. The TX Ethernet interface is used to send and receive control plane traffic.
Host for management and application control logic.
The vmsamp_ip324m_bicc application runs on the host, and accesses the board functionality through NaturalAccess and Video Access services:
From a software perspective, the 3G-324M over IP feature uses a Clear Channel gateway in front of Video Access 3G-324M gateway interface to tunnel H.223 data streams between TDM and RTP.
In the context of 3G-324M over IP, the clear channel gateway is also referred as H223 GW.
ITU BICC over SIGTRAN is used for call control and for establishing the RTP bearer channel settings and characteristics.
The vmsamp_ip324m_bicc application implements two configurable Bearer Control variants:
Forward bearer establishment with fast forward tunneling.
Forward bearer establishment with delayed forward tunneling.
vmsamp_ip324m_bicc does not support IPv6 or RTCP. Although RTCP is supported by NaturalAccess endpoints, an application limitation prevents it from being supported.
