Signaling Support
PRI ISDN, SS7, ESF, D4, SLC-96, Proprietary out of band, and robbed bit signaling is supported. Transparent support for Data, Modem or Fax. Voice quality is not compromised.

The IP•Tube UNO E1 ships with one E1 interface and one 10/100 BaseT Ethernet Interface. Optional integrated 4 port QOS/VLAN/Rate Limiting Layer-2 Ethernet switch is available. 

An Ethernet Switch Option provides transparent LAN bridging, user data bandwidth and access control through rate limiting and port-based VLAN filtering and tagging.

IP•Tube UNO E1 Standard Features

IP•Tube UNO E1 OPTIONS

Ethernet Switch OPTION - SWITCHThe IP•Tube UNO E1 is available with a four port 10/100 Ethernet QoS switch integrating a high-performance switching fabric with four priority queues. Advanced features include 802.1p/IPv4/IPv6 traffic classification, full IEEE 802.1Q VLAN, RMON, SNMP, Port Monitoring and Layer 2 firewall. QoS determined by destination MAC address, port ID, IEEE 802.1p and multimedia traffic tags, IPv4 Type of Service (TOS), and Differentiated Services (DiffServ).

Rate Limiter
The Ethernet switch Ingress and/or Egress Rate Limiter option enables the reservation of the bandwidth for time-sensitive E1 Over IP real time connections. Required for applications where the LAN traffic can exceed the WAN bandwidth required by the E1 over IP/Ethernet application. The data rate limit range is 128 kilobits to 64 Megabits in binary increments.The 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.

Virtual Private Network Support 
Interconnecting the IP•Tube UNO E1 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.

Protector OPTION -PRO
The protector option utilizes the Ethernet Switch port ETH1 as a redundant path for the interconnection of the IP encapsulated E1 data. The PRO Option is configured to Always-On, or with Switch-Over criteria.

Alternator Load Balancing OPTION -ALT 
The Alternator option alternatively sends the IP packetized E1 frames on two Ethernet interfaces, balancing the load. The Alternator option enables fractional and full E1 circuits to be split over two IP WAN connections such as ADSL.

Full E1 Connection Across Two ADSL Lines
The IP•Tube UNO E1’s two Ethernet interfaces are able utilize two ADSL Ethernet Modems, that have opposite high speed direction, to transport a E1’s symmetrical bandwidth.

DS0 Timeslot Multiplexor OPTION -MUX
The IP•Tube UNO E1-MUX maps DSOs from a central site to as many as 24 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.

Lossless Data Compression OPTION- C 

The IP•Tube UNO E1-C continuously detects idle and redundant data within each E1 Voice circuit resulting in as much as a 40 to 1 bandwidth savings.

E1 Over IP Ethernet Benefits

E1 Private Line Services over IP

The IP•Tube UNO E1 provides organizations 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 eliminated or dramatically reduced by transporting voice traffic across LANs and WANs.

E1 Over Wireless Ethernet

Interconnection of E1 based data communication systems over wireless as a primary or back up connection is a major application of the IPTube.

For over eight years the IPTube has proven itself around the world as an effective method for using Commercial Off the Shelf Wireless Ethernet Bridges to interconnect E1 circuits.

The IPTube’s Assured Delivery Protocol has the sophistication required for solid performance across a wide range of wireless connections.

The use of parallel Wireless Ethernet links minimizes the latency and Radio’s packet processing requirement. 
Note: Parallel Application requires Ethernet Switch Option.

Connecting phone systems across a wireless Ethernet connection has a return on investment that is measured in weeks. Eliminating the wired connection for the E1 based communication equipment is made possible with the IPTube’s E1 Over Ethernet capability.

Cellular Base Station Backhaul

IP•Tube UNO E1s provide transparent interconnection of Base Stations, Base Station Controllers and Mobile Switching Centers over IP Ethernet packet-switched networks.

Cellular service providers save substantially by converting to a packet switch network. The Lossless Data compression option, which is especially well suited to Cellular communication links, minimizes the bandwidth required to interconnect.

Cellular phone service providers are able to save substantially by converting to a packet switch network from circuit based TDM leased lines. The Loss Less Data compression option provides a 56 to 1 compression, which minimizes the bandwidth required to interconnect, is especially well suited to Cellular communication links. 

Engage's first deployment of the IPTubeE1, in the Spring of 2000, was for an international interconnection of a Cellular Base Station to a Base Station Controller.

Note: The Ethernet Switch Option has the sophistication to support Ethernet Native Base Station applications with QOS and rate limiting.

Broadband Service Providers

Utilities
Utilities generate new revenue by offering traditional E1 leased line and private line services over their fiber or power line networks.

Incumbent Carriers
Telcos reduce costs by delivering profitable leased and private line services over their flexible Ethernet infrastructures.

CLEC PBX Back Haul
The IP•Tube DLE1-Ecan provides CLECs with a way to back haul E1 DS0s from a customer’s phone systems over their Internet connection. The back hauled DS0s are connected to the CLECs phone switch for connection to the Public Switched Telephone Networks. Local Exchange Carriers are able to offer an economical alternative to the local Phone Company.

International Toll Bypass
The IP•Tube E1’s most dramatic cost savings is when it is used for the international interconnections of TDM based telecommunication equipment. The IP•Tube E1 is interoperable with the European TDM standard E1.
