- E1 Voice and Data over IP
The IP•Tube DLE1 encapsulates full and fractional E1 circuits into IP
packets. E1 Over IP connections provide for the interconnection of PBXs
and Telecom Switches via LANs, WANs, MANs, Satellite and Wireless
Ethernet.
The IP•Tube DLE1 ships with two E1 interfaces with either 1 or 2 active
and two 10/100 BaseT Ethernet Interfaces. The E1 interfaces have
configurations that for provide independent protocol, compression,
packet sizing, buffering, clocking, framing, coding and channel
settings. The inactive E1 Port can be activated via a software-based
license key for a pay as you grow option.
Transparent Interconnect
The IP•Tube DLE1's transparent operation maintains the proprietary
signaling required to support PBX features such as call conferences,
call forwarding, caller ID and SS7. Legacy phone equipment investment
is preserved. Signaling Support
PRI ISDN, SS7, and Proprietary out of band are supported. Transparent
support for Data, Modem or Fax. Voice quality is not compromised.
IP•Tube DLE1 Standard Features
- Assured Delivery Protocol
In order to assure high quality communications over links with
intermittent or noisy performance, such as Wireless or Broadband over
Power Line, the IP•Tube DLE1 employs Engage’s robust Assured Delivery
Protocol with the following benefits:
• Packet out of sequence detection and re-sequencing
• Duplicate skipping,
• Lost packet retransmission with configured delay.
Dual LAN Interfaces
All IP•Tube•DLE1 models ship with dual 10/100BaseT Ethernet LAN ports. The dual Ethernet interfaces provide for:
• Management interface on LAN port 2 when LAN port 1 is connected to a VPN tunnel
• The LAN ports can be configured to support connections over 2 opposite ADSL links
• Alternator Option for load balanced SDSL interconnects
• Protector Option for Redundant Packet Path connections with Constant or Switch Over Criteria
Full E1 Connection Across Two ADSL Lines
The IP•Tube DLE1’s two Ethernet interfaces are able utilize two ADSL
Ethernet Modems, that have opposite high speed direction, to transport
an E1’s symmetrical bandwidth.
Virtual Private Network Support -
Interconnecting
the IP•Tube DLE1 through a Virtual Private Network with sufficient real
time committed information rate ensures that the required quality of
service is provisioned. The second Ethernet interface provides a
management port. Each LAN interface features independent IP network
configurations.

DLE1 Options
DS0 Timeslot Multiplexor OPTION -MUX
The IP•Tube DLE1-MUX maps DSOs from a central site to as many as 31
remote locations via an IP/Ethernet connection. Get maximum use of
expensive DS1 interfaces on PBX, Channel equipment and datacom gear.
Also provides Virtual DACS Over IP capability. Mesh DS0s one-to-many or
many-to-many.
E1 Switch OPTION -SWT
The E1 switch option enables the E1 Port 1 interface to be manually
switched between a E1 circuit connected to E1 Port 2 or to E1 Over IP
packets connected with the remote IPTube.
• Remote Control of E1 Connection to Telco or E1overIP
• Installation performed by a single Technician
• Quick reversion to Telco during debug of E1overIP

E1 Link Protector OPTION -LPT
The E1 Link Protector provides an automatic back up for E1 circuits
with E1 Over IP connecting via Wireless Ethernet, Gigabit Ethernet, IP
Satellite Services, xDSL,....
• Automatic Protection Switch for E1 Circuit
• Deliver on Stringent Service Level Agreements
• Back Up for Mission Critical Connectivity
• Disaster Recovery for Public Safety Network

Lossless
Data Compression OPTION -C
The IP•Tube DLE1-C continuously detects idle and redundant
data within each E1 Voice circuit resulting in as much as a 56
to 1 bandwidth savings. TDM over IP WAN bandwidth is not consumed
by silent or redundant circuits. Note: Compression only supported
with IPTube•DLE1-C models.
Alternator
Load Balancing OPTION -ALT
The IP•Tube DLE1-ALT 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.
Rate Limiter OPTION -RLM
The
IP•Tube DLE1-RLM
Rate Limiter option limits the WAN bandwidth utilized by the LAN1 to
LAN2 bridge. Rate Limiting the traffic enables the reservation of the
WAN bandwidth for time the sensitive E1 Over IP real time connections.
Great for Wireless WAN E1 applications. Rate Governing is only applied
in the direction to the WAN to minimize latency. The data rate governor
utilizes Time Division Multiplexing based clocking to provide for Nx64,
NxE1 and NxFT3 bandwidth regulation that is configured from 64 kilobits
up to 45Mbits.

Protector OPTION -PRO
The
protector option utilizes the second LAN interface as a redundant path
for the interconnection of the IP encapsulated E1 Circuit. The
extension of the E1 circuit has a fault tolerant link that is
configured to always on, or with switch over criteria.
Protector OPTION -EnPRO
The
Enhanced version has configuration parameters that enable a secondary
packet path with high relative delay to primary path be synchronized.
The packet sequence delay synchronization ensures concurrent redundancy
with a high degree of error tolerance. Error free operation is
accomplished when a primary or secondary Packet is not received and a
redundant duplicate packet is available. The IPTube also supports the
transmission of multiple duplicate packets to support Mission Critical
Circuit extension with redundancy that is only limited by the bandwidth
provisioned.

Pay-As-You-Grow
Field Upgrades
The IP•Tube DLE1s are designed for Pay-As-You-Go growth from
1 E1 to 2 E1s. Customers can elect to economize initial installations,
buy purchasing a single active E1 port and enable the additional
E1 Port via a software-based license key.
Field Upgrade benefits are extended to our Industry-Best Loss less
Data Compression. Just as E1 ports are field upgrade able, so is
Loss less Data Compression. At any time, each E1 port on the IP-Tube
DLE1 can be upgraded to Loss less Data Compression
with a simple software-based license key installation. If you determine
that your IP•Tube DLE1 is best deployed with Loss less Data
Compression, you're still in business with the per port field upgrade!
Rack
Mount Kit
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
