SS7 Protocol Analyzer T1 Probe: 

The IP Tube GT1 SS7 MON encapsulates the SS7 Message Signal Units (MSUs), Link Status Signal Units (LSSUs), and optionally Fill-In Signal Units (FISUs) from the T1 monitor interfaces of Telecom Switches into IP packets.

These SS7 Over IP packets are sent to a Central Support Site, with the SS7 Protocol Expertise, where an IP Tube GT1 SS7 MON receives the SS7 Over IP packets and sends the SS7 Signaling units out four separate T1 interfaces or multiplexed onto a single T1 interface to an SS7 Protocol Analyzer.

The IP Tube GT1 SS7 MON has from 1 to 4 T1 interfaces that have the sensitivity, -36dB, to be connected to high impedance T1 Monitor jacks. The 4 T1 interface configuration provides for the simultaneous monitoring of the SS7 Signaling Units from Tandem Telco Switches.

  • Telco Switches
  • Signal Transfer Points
  • Mobile Switching Centers

Home Location RegistersThe IP Tube GT1 SS7 MON transparently transports SS7 messages over IP networks. SS7 signaling network elements such as local and tandem switches, Mobile Switching Centers, Signal Transfer Points and Home Location Registers that are interconnected to remote network elements by IP Tube GT1 SS7 MONs are able to transmit their signaling messages over cost effective and flexible IP networks.

IP Tube GT1 SS7 MON Standard Features: 

Industry Standard SS7 Framer
The IP Tube GT1 SS7 MON uses an industry standard SS7 Framer to receive and transmit SS7 messages. Minimal IP bandwidth is required to deliver SS7 since only Message Signal Units (MSUs), Link Status Signal Units (LSSUs) SS7 frames are encapsulated into IP packets.

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 MON 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 SS7 MON Optional Features: 

T1 Mutiplexor OPTION -MUX
The IP Tube GT1 SS7 MON with the MUX option has the ability to support remote SS7 messaging taps from 24 remote SS7 timelsots. A single SS7 Analyzer with 24 DS0s is able to simultaneously analyze 12 links.

SS7 Packets are enveloped in a SIGTRAN header so that an Ethernet Protocol Analyzer with an SS7 protocol decoder can be utilized to capture and analyze the IPTubes' SS7 Over IP traffic.

Protector OPTION -PRO
The protector option utilizes the second LAN interface as a redundant path for the interconnection of the IP encapsulated SS7 Circuit. The extension of the SS7 circuit has a fault tolerant link that is configured to always on, or with switch over criteria.

Pay-As-You-Grow Field Upgrades
The IP Tube GT1 SS7 MON has configurations with 1 to 4 integrated T1 interfaces each of which supports 1 to 31 SS7 Communication links. Designed for Pay-As-You-Grow expansion. Customers can elect to economize initial installation by purchasing a single active T1 port, and then enabling 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.
