RAILWAY EN50155 SIP-VOIP TO UIC568 GATEWAY

The Ermetris UIC 568 to SIP VoIP Gateway has been developed for the installations where a cab radio EIRENE, compliant with the UIC568 standard, has to be connected to an audio system realized with VoIP technology. The following scenarios are managed:

• Public Announcement (PA – UIC 568 std., Service PA)
• Train conductor recall (TC – UIC568 std., Service IC)
• Loco-Loco (TL – UIC568 std., IC Service)
• Environmental listening (AA – std. SES)

AA and TC/TL communications is mutually exclusive. When the AA is not used, the GW ensures compliance with the UIC 568 standard according to the priority rules recommended by EIRENE (chapter 4 Doc. 7) applied to vehicles where a VoIP network is implemented for the train sonorization.

The GW works in a system where a VoCM is installed.The GW make available two channels: one for the public announcement (PA) and another for full duplex communication in the event of a IC service (std. UIC 568). The following parameters has to be set by the user:

1. SIP User # 1 (for PA communications)
2. SIP User # 2 (for IC or AA communications)
3. SIP User # 3 (to produce a GONG sound that informs the conductor is requested to perform a TC call).

A Configuration Flag, to be set in the commissioning phase,  make the GW management of  the Intercom line in AA mode or in UIC568  Standard mode.
