PBX Over IP Solutions with IP•Tube T1/E1

The IPTube T1/E1 encapsulates the T1/E1 bit stream (both channelized and unchannelized) for
transport over IP. The IPTube T1/E1 ensures that the PBX-to-PBX signaling used on the point-to-point lines will get reproduced exactly on the other side of the IP pipe as originally transmitted. Just connect the PBX’s T1/E1 cable into the IPTube T1/E1 and you’re done. It's a GREAT deal!

The EngageIPTube T1/E1 provides a proven, economical solution for PBX communication over IP connections. There is no need to forklift upgrades to VoIP or IP Telephony.

The IP•Tube T1/E1 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 dramatically reduced or eliminated by transporting voice traffic across IP and Ethernet LANs and MANs that are becoming more and more ubiquitous:


The most compelling option for the interconnection of T1/E1 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.

Wireless Ethernet

Connecting phone systems across a wireless Ethernet connection has a return on investment that is measured in weeks.


Wide Area Networks with sufficient bandwidth and Quality of Service provisioning offer a compelling alternative to T1/E1-based terrestrial networks. Let' s explore some WAN options:

Competitive IP / Ethernet Service Providers

The list of Service Providers offering IP/Ethernet access networks are growing. The types of technologies that support reliable broadband IP/Ethernet is diverse:

Cable Operators

Cable operators deliver traditional Ethernet private line services over their hybrid fiber coax (HFC) cable modem termination systems (CMTS).

Metropolitan Area Networks

Metropolitan carriers have built fiber-optic based Gigabit Ethernet networks to support a menu of flexible Ethernet services.


Utilities continue to build state-of-the-art IP/Ethernet networks over their vast power system Rights-of-Way to offer broadband services over fiber optics or power line carrier (PLC) networks.

TheIPTube T1/E1transparent operation maintains the proprietary signaling required to support PBX voice communications. Voice quality is not compromised. The IPTube T1/E1 is available with one to four T1/E1 interfaces and with one to two 10/100 BaseT Ethernet interface(s). The T1/E1 interfaces have configurations that provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The protocols supported are IPTube and CESoIP.

TheIPTube T1/E1•C adds the power of lossless data compression. This optional functionality continuously detects idle/redundant data within each DS0 resulting in as much as a 56 to 1 bandwidth savings. TDM over IP bandwidth is not consumed by silent or redundant circuits. The IPTube T1/E1•C lossless data compression option is ideal for environments where network bandwidth is limited such as point-to-point and point-to-multipoint wireless, HFC cable modems, xDSL, Power Line Ethernet or the Internet.
