E1 Voice over IP
The IP Tube GE1-Ecan encapsulates full and fractional E1 circuits into IP packets. E1 Over IP connections provide for the interconnection of Channel Banks, PBXs and Telecom Switches via LANs, WANs, MANs, Satellite and Wireless Ethernet.
The IP Tube GE1-Ecan ships with four E1 interfaces with Echo Cancellation and two 10/100 BaseT Ethernet Interfaces.
The IP Tube GE1-Ecan has four independent integrated E1 Echo Cancellers that cancel up to 64 milliseconds of Far End echo. The Echo Canceller DSP detects and cancels echo at the far end so that the interconnecting packet's network delay and jitter has no impact on echo. The echo canceller meets ITU-T G.164, G.165 and ITU-T G.168 requirements for echo cancellation.
Echo is one of the most important factors that affects voice quality. The primary source of echo is the impedance mismatch at the hybrid that links a 2-wire analog loop to a 4-wire digital trunk. Echo Cancellation is essential for E1 circuit emulation that involves voice connections to the PSTN and delay in excess of 20 milliseconds. Packet networks that traverse an intranet or Internet backbone can easily exceed 20 milliseconds. The IP Tube's Echo Cancellation provides the elasticity to support high quality voice connections across networks with significant delay and packet jitter.
The primary purpose to employ E1 Circuit Over Packet technology is to reduce or ideally eliminate the E1 leased circuit charges. For an enterprise utilizing their existing intranet is very compelling. Typically these intranets are already handling a very demanding load with significant packet jitter. The IP Tube Echo Cancellation has jitter buffering greater than 100 milliseconds which is more than enough for the majority intranets and beyond the signaling delay tolerance of Voice PBX or Switch.
Choosing Wireless Ethernet for the transport of E1 Circuit Emulation is very popular since the circuit lease charges are eliminated. Commercial Off the Shelf Wireless Ethernet radios do not perform well with full duplex E1 circuit emulation packet traffic that is configured to keep the round trip less than 20 milliseconds. The IP Tubes Echo Cancellation has the elasticity (Jitter Buffering and reduced Packet Frequency) to support the use of Wireless Ethernet for E1 Circuit Emulation.
The IP Tube GE1-Ecan's transparent operation maintains the proprietary signaling required to support PBX features such as call conferences, call forwarding, caller ID and SS7.
Robbed Bit, PRI ISDN, SS7, and Proprietary out of band are supported. Echo cancellation is automatically disabled during FAX and Modem communications. Transparent support for Modem or Fax. Voice quality is not compromised.
Note: Legacy phone equipment investment is preserved.
