VoIP phone calls are usually delivered over a carefully-managed network often running Quality of Service (QoS) and the Session Initiation Protocol (SIP).

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 over Internet Protocol (IP), or VoIP, is a managed voice and Internet solution for businesses that falls into the industry niche referred to as IP Centrex (a feature-rich hosted analog voice solution), or Hosted Private Branch Exchange (PBX) that provides many features and capabilities that transform business communications beyond what traditional voice and data networks can offer.

Our clients include Fortune 500 Companies, Small-to-Medium Businesses (SMBs) Governmental Agencies, Defense Contractors, Hospitals, Law Offices, Internet Service Providers, Wireless ISPs, State Universities, Web Hosting Companies, etc.

Ethernet can be used to connect twisted copper pair networks and to connect fiber optic cable networks.

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.

A major feature of Internet over Ethernet is the ease in which you can upgrade from 1 Mbps to 1 Gbps. Simply call your Internet Service Provider (ISP) and ask for an upgrade and it can be provisioned almost in real time. This service is the future of Internet access for the foreseable future.

Digital Subscriber Line Service (DSL) has become a very popular Internet access service. This is because DSL uses the existing copper pairs that already exist between most customer premise offices and the local phone company central office (CO). A DSL connection is set up between a DSL modem at the customer premise and a DSL access multiplexer, or DSLAM, at the phone company central office. Both voice and data can be run across the same DSL connection by using a filter to separate voice traffic from Internet traffic.
