Description
Overview
T3 Voice, Video and Data Over IP
The IP•Tube T3 encapsulates DS3 circuits into IP Ethernet packets. The conversion of T3 circuits into packets enables organizations to dramatically reduce leased line costs by exploiting the efficiency of Ethernet networks. T3 Toll charges assessed by long distance and local carriers are eliminated or dramatically reduced for:
- Competitive Local Exchanges
- Internet Service Providers
- Education: K-12 and Universities
- Multi-Site Enterprises
- Cellular Service Operators
- Governments and Municipalities
Transparent Protocol and Signaling
The IP•Tube T3’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 IP•Tube T3’s low latency T3 Over IP connection provides for the transparent interconnection of Private Branch Exchanges, Mobile Switching Centers, Telecom Switches and T3 based communication systems via: LANs, WANs, MANs, IP Satellite and Wireless Ethernet

IP•Tube T3 Standard Features
Service Quality Packet Prioritizing
The IP•Tube T3 uses the Type of Service byte in the IP packets to prioritize the encapsulated T3 frames. The setting of the TOS byte can be used to ensure that the real time TDM data from the IP•Tube T3 is ensured high priority. Additionally 802.1p/q VLAN tagging provides layer 2 prioritization.
Management Interface
Management of the IP•Tube T3’s 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.
IP•Tube T3 Optional Features
Protector Option -PRO
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated T3 Circuit. The extension of the T3 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.
Alternator Load Balancing Option -ALT
The IP•Tube T3-Alt Alternator option alternatively sends the IP packetized T3 frames on LAN 1 and LAN 2. The Alternator option enables the bandwidth required to transport T3 circuits to be split over two WAN connections.

Rack Mount Kit
The IP•Tube family is ready for your most demanding central office or data center environments. With the Rack Mount Kit, IP•Tube products are easily installed in 19″ and 23″ racks. Easy access to both front and rear sides facilitates technician maintenance procedures.
Applications
T3 Private Line Services over IP
Multi-Site Enterprises, Cellular Service Providers, Education Districts, Universities, National, State and Local Government, and Municipalities incur significant recurring monthly costs for rigid-bandwidth leased lines used only for the interconnection of PBXs and Telecom switches.
The IP•Tube T3 provides organizations with the ability to interconnect their existing T3 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.
LANs
The most compelling option for the interconnection of T3 based systems is when it can be accomplished over a Local Area Network. The deployment of Fiber based LANS such as 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.
Cellular Base Station Backhaul
IP•Tube T3s are used to provide transparent interconnection of the Base Stations, Base Station Controllers and Mobile Switching Centers over IP Ethernet packet-switched networks.
Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit based TDM leased lines.
Broadband Service Providers
Companies, that are able to provide IP Ethernet access networks generate new revenue by offering traditional T3 leased line and private line services, such as:
Cable Operators
Cable operators connect traditional T3 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 T3 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 T3 provides CLECs with a way to back haul T3 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 T3 based communication equipment is made possible with the IP•Tube T3s Over Ethernet capability.

International Toll Bypass
The IP•Tube T3’s most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment.
