E3 Voice, Video and Data Over IP 
The IP•Tube E3 encapsulates E3 circuits into IP Ethernet packets. The conversion of E3 circuits into packets enables organizations to dramatically reduce leased line costs by exploiting the efficiency of Ethernet networks. E3 Toll charges assessed by long distance and local carriers are eliminated or dramatically reduced for:

Transparent Protocol and Signaling
The IP•Tube E3's transparent operation maintains the proprietary signaling required to support call conferencing, call forwarding, caller ID and SS7. Transparent support for Modem, Fax, or Data circuits. Preserves toll-quality voice across the network.

The IIP•Tube E3's low latency E3 Over IP connection provides for the transparent interconnection of Private Branch Exchanges, Mobile Switching Centers, Telecom Switches and E3 based communication systems via:

Service Quality Packet Prioritizing 

The IP•Tube E3 uses the Type of Service byte in the IP packets to prioritize the encapsulated E3 frames. The setting of the TOS byte can be used to ensure that the real time TDM data from the IP•Tube E3 is ensured high priority. Additionally 802.1p/q VLAN tagging provides layer 2 prioritization.

Management Interface
Management of the IP•Tube E3 is accomplished with a Command Line Interface that is accessed through a Console or Telnet connection. Templates of the most common configuration provide for an Edit and Paste configuration. SNMP MIB I and II support, with traps, is a standard feature.

Protector Option
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated E3 Circuit. The extension of the E3 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.

The IP•Tube E3 provides organizations with the ability to interconnect their existing E3 Communication 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 or dramatically reduced by transporting voice traffic across LANs and WANs.

Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit based TDM leased lines.

Companies, that are able to provide IP Ethernet access networks generate new revenue by offering traditional E3 leased line and private line services, such as:

 

Cable Operators

Cable operators connect traditional E3 leased line and private line services over their hybrid fiber coax (HFC) cable networks. HFC Cable network latency typically requires echo cancellation.

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 E3 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 IP•Tube E3 provides CLECs with a way to back haul E3 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. Local Exchange Carriers are able to offer an economical alternative to the local Phone Company.

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 E3 based communication equipment is made possible with the IP•Tube E3 Over Ethernet capability.
