“…Therefore, VoIP systems implement tone relay protocols to ensure that in-band signaling functions properly. 17,18 The following protocol standards exist for VoIP signaling: the H.323 framework 19,20 The routing of requests is mostly determined by the request uniform resource identifier (URI) contained in the request. SIP request URIs look similar to e-mail addresses, consisting of a user name part and a hostname part, plus a number of parameters.…”

The recent interest in IP as the vehicle for transporting TDM and narrowband services stems from the possibility of using a common transport network for voice, video, and data, and the flexibility with which new services can be introduced. A key step in the evolution of networks towards a 'broadband' IP-based environment is the 'graceful' interworking of the IP networks with the existing networks and services, particularly with the circuit switched telephone network. A 'graceful' interworking approach is one whose complexity is minimal and preserves the user's perceived quality of service (QoS). To interwork with a circuit switched network whose services are pre-dominantly time-sensitive, the IP network must essentially behave as a transparent 'link' in the end-to-end connection. This paper presents an overview of the main technical problems to be addressed when trunking TDM and narrowband services over IP networks.

“…Other nodes in the IM subsystem include the breakout gateway control function (BGCF), media gateway control function (MGCF), IM-media gateway function (IM-MGW), and transport signaling gateway function (T-SGW). These nodes are typically used in a voice over IP (VoIP) network [12,13], and will be elaborated on in subsequent sections. Most interfaces among these nodes (i.e., Mc, Mg, Mh, Mm, Mr, and Ms) are IPbased gateway control protocols.…”

“…The media gateway control function (MGCF) is the same as the MGC in a VoIP network [12], which controls the connection for media channels in an MGW. The MGCF communicates with CSCF through SIP over the Mg interface.…”

The objective of this article is to present a promising voice over digital subscriber line (VoDSL) solution: an alternative method that uses physical layer transportation to provide channelized VoDSL (CVoDSL). This article also presents the advantages that the CVoDSL provides to the customers in terms of high-quality services and lower cost, and service providers in terms of market growth and success. It also offers a set of requirements, architectural design, and implementation scenarios that provide end-to-end solutions for CVoDSL.
