IP•Tube GT1 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 GT1 SS7 SIG 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 GT1 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 

Service Quality Packet Prioritizing 
The IP•Tube GT1 uses the Type of Service byte in the IP packets and 802.1p/q mac level prioritization to prioritize the encapsulated SS7 Messages.

VPN Network Management    
Interconnecting the IP•Tube GT1 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 GT1'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.

IP•Tube GT1 Optional Features

T1 Drop and Insert OPTION -D&I
The 2nd T1 Interface can be activated to provide a Drop and Insert interface for direct inline connection to the SS7 DS0 without requiring a DACs. 

T1 Mutiplexor OPTION -MUX
The IP•Tube GT1 SS7 SIG with the MUX option has the ability to support remote SS7 messaging taps from 24 SS7 timelsots.

Protector OPTION -PRO
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated T1 Circuit. The extension of the T1 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 IP•Tube 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 GT1 SS7 SIG has configurations with 1 to 4 integrated T1 interfaces each of which supports 1 to 31 SS7 Communication links. The IP•Tube GT1 SS7 SIG is designed for Pay-As-You-Grow expansion.  Customers can elect to economize initial installation by purchasing a single active T1 port, and then enabling an additional SS7 DS0s or T1 ports via an option license key.

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 procedures.
