At Kolkata ATC Center (India), SITTI has successfully performed installation testing and commissioning of its top-edge Multifono M800IP Voice Communication System (VCS).
For the first time in India, a “Fully VoIP” VCS has been installed and commissioned.
Kolkata is one of the four ACC centers in India; it covers the Eastern Region (Kolkata FIR).
The VCS is connected to the IP radios through MPLS network and E1 connection for media redundancy.
- As for MPLS connectivity, the VCS is connected directly to the radio using latest ED137B protocol.
- As for E1 connectivity, SITTI is using Remote Management Units (RMU) installed in remote stations, connected to the VCS through E1 and to the radios through 4W-EM connection.
In order to save bandwidth, fractional E1 is used to connect RMUs to the VCS.
Kolkata VCS figures are impressive:
- 100 CWP
- 106 IP radio channels
- 58 analogue radio channels (connected through E1 and 4W connections)
- 90 IP telephone lines
- 44 analogue telephone lines
- 10 RMU (Remote management Unit)
- 750 VoIP recording channels
SITTI is proud of this outstanding success and will continue to support the Airport Authority of India (AAI) during shadow-mode operation and transition period.
