One to Four E1 interfaces for E1 over IP Voice and Data
The IP•Tube QE1 is available with one to four E1 interfaces
and dual 10/100 BaseT Full/ Half Duplex Ethernet Interfaces. The
E1 interfaces have configurations that for provide independent
protocol, compression, packet sizing, buffering, clocking, framing,
coding and channel settings. Enable additional E1 Ports as needs
expand using a software-based license key. The protocols supported
are IPTube, CESoIP, and HDLCoIP.
IP•Tube 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.
Data Compression Option
IP•Tube-E1C detects idle/redundant data within each DS0
resulting in as much as 56 to 1 bandwidth savings. E1 over IP
bandwidth is not consumed by silent or redundant circuits. Management
of the IP•Tube E1 is accomplished with a Command Line
Interface that is accessed through a Console or Telnet connection.
Common templates provide for cut and Paste configuration.
Quality Packet Prioritizing
The IP•Tube QE1 uses the Type of Service byte in the IP packets
to prioritize the encapsulated E1 frames. The setting of the TOS
byte can be used to ensure that the real time TDM data from the
IP•Tube QE1 is ensured high priority.
Load Balancing Option
The IP•Tube QE1A Alternator option alternatively sends the
IP packetized E1 frames on LAN 1 and LAN 2. The Alternator option
enables fractional and full E1 circuits to be split over two IP
WAN connections such as xDSL. The Lossless Data Compression option
can be combined with the Alternator option to minimize the bandwidth
required from the alternative paths. The cost of interconnecting
E1 communication systems across packetized xDSL is a fraction of
long distance leased E1 circuit costs.
The IP-Tube QE1/ QT1 are designed for Pay-As-You-Go growth from
1 E1 thru 4 E1s per IP•Tube QE1. Customers can elect to economize
initial network installations, by purchasing their IP-Tube QE1 with
a single active E1 port. As the network grows enable additional
E1 Ports via a software-based license key. Field upgrade benefits
are extended to our Industry-Best Lossless Data Compression. Just
as E1 ports are field upgradeable, so is Lossless Data Compression.
At any time, each E1 port on the IP-Tube QE1 can be upgraded to
Lossless Data Compression with a simple software-based license key
installation. If upon installation, you determine that your IP•Tube
QE1s are best deployed with Lossless Data Compression, you're still
in business with the per port field upgrade!
Interconnecting the IP•Tube QE1 through a Virtual Private
Network with a sufficient real time committed information rate ensures
that the required quality of service is provisioned. The IP•Tube
QE1's second Ethernet interface provides a management port when
the first Ethernet interface is connected to a VPN. Each Ethernet
LAN interface features independent IP network configurations.
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
