T1 Services over IP
The IPTube-T1 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.

HDLC over IP
IPTubes with HDLCoIP connect to the T1 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.

CLEC PBX Back Haul
The IPTube-T1 provides CLECs with a way to back haul a T1 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-T1's most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment. The IPTube-T1 is interoperable with the European TDM standard E1.
