TheIPTube G4 E1provides 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 longdistance and local carriers are eliminated or dramatically reduced by transporting voice traffic across packet-switchedinfrastructure. The following organizations incur significant recurring monthly costs for rigid-bandwidth leased lines used onlyfor the interconnection of PBXs and Telecom switches.

Transparent leased and private line servicesover less expensive IP and Ethernet networks

Operating expenses are minimized by leveraging the

efciencies and ubiquity of IP, Ethernet and MPLS

Protects investment in traditional telephony andTDM equipment.

Ethernet, IP and MPLS infrastructures areinexpensive, fast to provision and scalable.

Cellular service providers save substantiallyby converting to a packet switch network.The Lossless Data compression option,which is especially well suited to Cellularcommunication links, minimizes the

bandwidth required to interconnect.

Note: The Ethernet Switch Option has thesophistication to support Ethernet NativeBase Station applications with QOS and ratelimiting.

Wireless EthernetThe IPTube has proven itself around the world as an effectivemethod for using Commercial Off the Shelf Wireless EthernetBridges to interconnect E1 circuits.

Interconnection of E1 based data communication systemsover wireless as a primary or back up connection is a majorapplication.

The IPTubes Assured Delivery Protocol has the sophisticationrequired for solid performance across a wide range of wirelesconnections.

The use of parallel Wireless Ethernet links minimizes thelatency and Radios packet processing requirment.Note: Parallel Application requires Ethernet Switch Option.

E1 PRIVATE LINE SERVICES OVER IP

LANsThe most compelling option for the interconnection ofE1 based systems is when it can be accomplished over aLocal Area Network. The deployment of Fiber based LANSsuch as Gigabit Ethernet, provides organizations with highperformance and high quality bandwidth that is especiallywell suited for the interconnection of PBXs and Switches.

WANsWide Area Networks that have sufficient bandwidth andQuality of Service provisioning result in very significant costsavings especially for Multi-Site Corporations. TheIPTubeG4 E1-Cwith lossless data compression, detects idle andredundant data within each voice circuit resulting in asmuch as 56 to 1 bandwidth savings.

The SuperTube option multiplexes four E1 circuits onto one IP packet stream. The SuperTube Sized IPTube reduces theencapsulation overhead bandwidth and the packet frequency by 75%. The substantial reduction of packet frequency enablesnetwork packet processors, such as wireless Ethernet radios and WAN routers/bridges, that can be overstressed with the lowlatency packet processing to reliably support the extension of real time circuits over their packet networks.

Assured Delivery ProtocolIn order to assure high quality communications over linkswith intermittent or noisy performance, such as Wireless orBroadband over Power Line, the IPTube G4 E1employsEngages robust Assured Delivery Protocol with the followingbenefits:

Packet out of sequence detection and re-sequencing

Duplicate skipping Lost packet retransmission with congured delay.

Dynamic Host Configuration Protocol - DHCPThe IPTube G4 E1can be configured to obtain its InternetProtocol network parameters: IP Address, Subnet Mask, De-fault Gateway, DNS; from a local DHCP server.

Domain Name AddressingIPTube G4 E1can be configured to use a Domain Name forthe remote IPTube in place of a xed IP address. Supportsmobile multi service provider installations with ease.

Dynamic DNSIPTubes can be congured to register their IP address withDynamic Domain Name Servers for discovery by the IPTube atthe other end of the E1 circuit. DDNS support combined withDHCP make installations Name-based which is very easy tosetup and maintain when compared to Static IP addressing.

Secure Socket Shell - SSHEngages Secure Socket Shell, which is based upon industryproven Open SSH and FIPS 140 approved Open SSL version2.0, provides secure encrypted communications betweenSSH clients such as OpenSSH, SecureCRT, and PuTTY and theIPTubes Command Line Interface.

SNMPThe IPTube G4 E1 is able to be fully managed with SNMPvia standard and private MIBs. Large scale deployments ofIPTubes with centralized management have made SNMP sup-port a priority. SNMP Traps for error events enable proactiveservice fault isolation.

Protector OPTION -PROThe protector option utilizesthe Ethernet Switch portETH1 as a redundant path forthe interconnection of the IPencapsulated E1 data.

The PRO Option is configured toAlways-On, or with Switch-Overcriteria.

IPTube G4 E1 Standard Features

Alternator OPTION -ALTThe Alternator option alternatively

sends the IP packetized E1frames on two Ethernet

interfaces, balanacing the load

The Alternator option enablesfractional and full E1 circuits to besplit over two IP WAN connections

such as ADSL

IPTube G4 E1 Optional Features

The IPTube G4 E1is available with a four port 10/100 Eth-ernet QoS switch integrating a high-performance switchingfabric with four priority queues. Advanced features include802.1p/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, IEEE802.1p and multimedia traffic tags, IPv4 Type of Service

(TOS), and Differentiated Services (DiffServ).

Rate LimiterThe Ethernet switch Ingress and/or Egress Rate Limiter optionenables the reservation of the bandwidth for time-sensitiveE1 Over IP real time connections.

Required for applications where the LAN traffic can exceedthe WAN bandwidth required by the E1 over IP/Ethernetapplication. The data rate limit range is 128 kilobits to 64

Megabits in binary increments.
