One of the advantages of VoIP is that voice and Internet services are delivered over the same local loop access circuit using the Internet Protocol (IP).

An Internet T1 (or T-1 line) is a digital, dedicated local access connection supporting data rates of 1.544 Megabits Per Second (Mbps) that can be channelized into 24 individual channels that each provide 64 Kilobits Per Second (Kbps).

VoIP can provide big company telephone features on a small company budget. You are not merely trading one system for another: VoIP represents the next generation of telephony and messaging: Control calls anytime from anywhere, view incoming calls, view missed calls, view calls you have placed, view your voice messages like emails (find the voice message you want to listen to first – listen to it through your phone, remotely, or on any sound-enabled computer, forward it to another user or an email box), click to call people in your contact directory, enjoy four-digit dialing to all of your locations, etc.

MPLS VPNs use Multiprotocol Label Switching (MPLS) to set up Virtual Private Networks (VPNs) that can isolate data traffic to provide Class of Service (CoS), Quality of Service (QoS), and ease network administration with minimal network overhead. Layer 3 MPLS VPNs (L3VPNs) use BGP, traffic isolation and Virtual Routing / Forwarding (VRF) for network routing and security. MPLS VPNs are more efficient and robust than IPSec VPN, ATM, MPLS L3VPNs.

Ethernet provides a great local access medum to connect LANs to the Internet and is quickly becoming the access method of choice were it is available.

DSL has become a widely-accepted and increasingly reliable method of delivering phone service and providing Internet access that saves end users money because both voice and data are delivered across the same plain old telephone serivce (POTS) line. However, the distance to the local phone company central office where the copper POTS line is connected from the customer premise to the DSLAM will determine the potential speed of the DSL connection.
