E1 Over IP Interconnect for Voice and Data

The IPTube•QE1 encapsulates full and fractional E1 and TDM circuits, along with their framing and signaling bits, into IP packets. The IPTube•QE1's E1 Over IP, E1 Over Ethernet connection provides for the transparent interconnection of PBXs, Telecom Switches and E1 based communication systems via LANs, WANs, MANs, Satellite and Wireless Ethernet.

The IPTube•QE1 is available with one to four E1 interfaces and a 10/100 BaseT Full/Half Duplex Ethernet Interface. The E1 interfaces have configurations that for provide independent protocol, compression, packet sizing, buffering, clocking, framing, coding and channel settings. The protocols supported are IPTube, CESoIP, and HDLCoIP.

Transparent Interconnect
The IPTube•QE1's transparent operation maintains the proprietary signaling required to support PBX features such as call conferencing, call forwarding, caller ID and SS7. Legacy phone equipment investment is preserved. Transparent support for Modem, Fax, or Data circuits. Voice quality is not compromised.

IP Cellullar Back Haul
IPTube•QE1s are used to provide transparent interconnection of the base stations (BTSs), base station controllers (BSCs) and mobile switching centers (MSCs) over IP Ethernet packet-switched networks. Supported access media include fiber, coax and fixed wireless. Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit TDM lease lines. The IPTube•QE1 has the Duplicate packets transmission and reception feature that provides for resilient performance through a lossy interconnect.

Lossless Data Compression
The IPTube•QE1C detects idle/redundant data within each E1 Voice circuit resulting in a as much as a 40 to 1 bandwidth savings. The IPTube•QE1C compression works from the lowest latency setting of 8 E1 frames to the highest setting of 40 E1 frames per packet. TDM Over IP WAN bandwidth is not consumed by silent or redundant circuits and voice quality is not effected.  Note: Compression only supported with IPTube•QE1C model.
