MAPS ED-137 Telephone - Air Traffic Network

MAPS™ ED-137 Telephone Software Ver 8.3.19 (64-bit Only) | Download Now!

Overview

Recent advances in Air Traffic Management over IP network has opened up both opportunities for providing better services, and challenges to ensure reliability, and performance. Among many other solutions for testing Air Traffic Control network, GL offers MAPS™ ED137 Telephone (PKS119) which can simulate Ground-Ground (as per EUROCAE ED137_2B: Telephone) calls.

MAPS™ ED137 Telephone simulates the functions of Controller Working Position (CWP) in Ground-to-Ground telephone calls. The product supports transmission and detection of various RTP audio traffic such as real-time audio, voice file, digits, single tone and dual tones. The MAPS™ profile editor feature allows users to easily configure multiple CWPs profiles, allowing to simulate multiple CWP entities.

GL tools for signalling emulation and voice quality testing offer an end-to-end test solution for testing connections from the radio interfaces to the Controller Working Position (CWP) and recording voice communications in the ATM network. GL’s Air Traffic Management Solution also includes MAPS™ ED-137 Recorder Emulators and MAPS™ ED-137 Radio Emulators.

GL also provides a GUI based PacketScan - All IP Traffic Analyzer for online capture and decode of the signaling in real time both during tests and as a stand-alone tracer for live systems.

Main Features

Signalling and Traffic Simulation

  • Emulates ED-137/2B Telephone interface at CWP endpoints.
  • Enhanced to support multiple CWP endpoints simulation
  • Portable, easy to configure and use during in-the-field installation, system configuration/ test and commissioning
  • Supported call types include Instantaneous Access, Priority Direct/Indirect Access, Routine Tactical Direct/Indirect Access, Routine Strategic Direct/Indirect Access, Routine General Purpose Direct/Indirect Access, and Position Monitoring (Combined A/G and G/G, A/G only, and G/G only) Call
  • Supports SIP Headers defined in ED-137/2B.
  • Depicts easy to understand Call Flow Graphs of SIP message exchanges and Displays Message contents (SIP headers and SDP attributes).
  • Allows call rejection through use of SIP response codes (4xx, 5xx, 6xx)
  • Supports multiple Profiles (Users/End points) from single node.
  • Supports hundreds of simultaneous calls and load generation can be automated completely along with traffic.
  • Allows to define DSCP (Differentiated Service Code Point) values for signaling and voice traffic.
  • Supports complete customization of SDP and SIP headers, call flow, and messages.
  • Supports both UDP and TCP (IPv4 and IPv6).
  • Handles Re-transmissions of messages with specific interval.
  • Supports User authentication with Proxy, Registrar servers
  • Supports IP address spoofing for each endpoint to generate call using different IP address from a single system.
  • Supports OPTIONS PING feature used to check the connection status

Traffic

  • Supports various traffic actions on the call such as Playback to Speaker, Send & Record audio file, Generate and detect inband digits, single tone and dual tone.
  • Supports ED137 defined codecs - G.711 (mu-Law and A-Law) and G.729
  • Supports User-defined and automated traffic actions on the call.
  • Applies impairments to the traffic such as Packet Loss, Latency, Duplicate and Out of sequence.
  • Provides aggregated voice quality statistics such as MOS/R-Factor, Packet Loss, Duplicate and out of sequence packets.

GUI Features

  • Call Generation and Call Reception Window includes button options to apply Events on an ongoing call.
  • Provides call statistics such as Active, Completed, Passed, Failed and Calls per second
  • Provides Event logs, Captured errors and Error events.
  • Automation, Remote access, and Schedulers to run tests 24/7
  • Supported on Windows® 7, 8 or higher version operating systems.
  • Supports 64-bit version to enhance signaling performance.

CLI

  • Supports Client-Server functionality requires additional license; clients supported are TCL, Python, VBScript, Java, and .Net.

Applications

  • Fully integrated, complete test environment for Air Traffic Management.
  • Supports testing CWP, VCS, GRS (or RMG), and VRS.
  • Handles strict routing & loose routing, when requests are routed through proxies.

MAPS™ ED137 Telephone Simulation

Typical SIP Procedure

A typical ED137 Telephone call between CWP entities in the Ground-to-Ground call using MAPS™ ED137 at one of the peer-end is as shown.

Ground-Ground Call Simulation (as per ED137_2B: Telephone)

MAPS™ ED137 Telephone can be configured as CWP for placing and receiving calls, thus generating telephone calls.

Once call is established between the two terminals, transmission and detection of various RTP audio traffic such as real-time audio, voice file, digits, single tone and dual tones are also supported with additional licenses.

User-friendly GUI features allows users to manually start/stop traffic, impair the traffic (latency, packetloss, and packeteffect), transfer call, put active call on hold, and playback the call using Speaker On option.

Supported call types includes the following -

  • Instantaneous Access
  • Priority Direct/Indirect Access
  • Routine Tactical Direct/Indirect Access
  • Routine Strategic Direct/Indirect Access
  • Routine General Purpose Direct/Indirect Access
  • Position Monitoring (Combined A/G and G/G, A/G only, and G/G only) Call
