E1 Services over IP
The IPTube•QE1 provides enterprises with the ability to interconnect their existing phone systems over flexible bandwidth lines that are used to carry data, voice, and video. The Voice Only Leased Line Toll charges assessed by long distance and local carriers are eliminated by transporting voice and fax traffic across the enterprise intranet, LAN, Metropolitan-Area Network, WAN, or Wireless.

LANs
The most compelling option for the interconnection of E1 based systems over Ethernet is when it can be accomplished over a Local Area Network. The deployment of Fiber based LANS such as FDDI and Gigabit Ethernet, provides organizations with high performance and high quality bandwidth that is especially well suited for the interconnection of PBXs and Telecom Switches.

WANs
Wide Area Networks that have sufficient bandwidth and Quality of Service provisioning result in very significant cost savings especially for Multinational Corporations. The IPTube•QE1•C, a model with lossless data compression, detects idle and redundant data within each voice circuit resulting in a 40to 1 bandwidth savings. WAN bandwidth is not consumed by silence or redundant samples.

Wireless Ethernet
Connecting phone systems across a wireless Ethernet connection has a return on investment that is measured in weeks. Eliminating the wired connection for the E1 based communication equipment is made possible with the IPTube's E1 Over Ethernet capability.

Competitive IP Ethernet Service Providers
Companies, that are able to provide IP Ethernet access networks generate new revenue by offering traditional E1 leased line and private line services, such as:

Cable Operators
Cable operators connect traditional E1 leased line and private line services over their hybrid fiber coax (HFC) cable networks.

Metropolitan Area Networks
Metropolitan carriers with IP or Ethernet access networks deliver traditional leased line and private line services.

Utilities
Utilities generate new revenue by offering traditional E1 leased line and private line services over their fiber or power line networks.

Incumbent Carriers
Telcos reduce costs by delivering profitable leased and private line services over their flexible Ethernet infrastructures.

CLEC PBX Back Haul
The IPTube-E1 provides CLECs with a way to back haul a E1 DS0s from a customer's phone systems over their Internet connection. The back hauled DS0s are connected to the CLECs phone switch for connection to the Public Switched Telephone Networks. Competitive Local Exchange Carriers are able to provide customers with a very economical alternative to the local Phone Company since the Local Loop charges of around $40/line per month for each phone line are consolidated.

International Toll Bypass
The IPTube-QE1's most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment. The IPTube-E1 is interoperable with the American TDM standard T1.

HDLC over IP
IPTubes with HDLCoIP connect to the E1 leased line interface of an Enterprise's WAN Router and encapsulate the HDLC frames into an IP Packet that is sent to the remote site IPTube where it is presented to the remote WAN router as the original HDLC frame. Enterprises are able to connect to broadband IP services through their existing proven WAN infrastructure. Internal Ethernet networks remain isolated and security services such as Firewalling are maintained.
