Here is the text portion of the presentation.
 
IAD-Integrated Access Devices provide the service known as integrated access also known as converged access (“flex” services) a digital communications service which provides voice telephony connections as well as high speed data communications over the same T-1 circuit. While integrated access service has been around for more than five years, new dynamic bandwidth and other capabilities are now available. While the difference between integrated and converged access is often more marketing than actual, integrated access usually refers to as fixed allocation of bandwidth. For example, the carrier would provide up to 50% of the bandwidth or 12 channels for telephone connections and the remainder or 768 kilobits per second for internet or wide area data networking. 
 
With integrated/converged access, as shown here, bandwidth is not fixed but allocated based on need. Voice is prioritized for high quality of service or QoS. One carrier provides up to 10 high quality and up to 40 low quality voice calls with the remainder of the bandwidth available for data. This means if no one is the phone, the entire T-1 bandwidth is available for data communications. In addition, VoIP-Voice over Internet Protocol, SIP and other features are available depending on specific carrier offerings. 
 
One of the many types of SIP Trunking will be using current IAS-Integrated Access Service also known as CAS-Converged Access Service to support SIP signaling. That is, the provider SBC-Session Border Controller would act as a SIP Proxy server to support SIP UAC-User Agent Client devices, Microsoft OCS-Office Communications Server, softphone clients, analog and other signaling protocols such as FAX and T.38 FAX. QoS is also supported in the LAN via 802.1p/q and on the WAN DSCP-Differentiated Services Code Points or separate MPLS-Multi-Protocol Label Switching. In addition, SIP trunking will be offered via metro/gigabit ethernet. Among the many providers of this technology is Nortel with the CS2100.
