NCTD North County Transit District - Sprinter Light Rail

VoIP, EmVista Central

For Sprinter, Emcom Systems has provided the Authority’s newly built Light Rail System with a redundant, expandable, VoIP, EmVista Central, head-end system including 7 Emvista Agent Stations with audio interfaces and one EmVista Maintenance Station, all implemented by B&C Transit Consultants.

The EmVista Central System provides endpoint connections to analog Emergency Call Boxes through VoIP telephony gateways on the network. These Emergency Call Boxes are configured and tested through the EmVista Maintenance Station.

The system also provides endpoint connections to the Sprinter Radio System. Radio connections appear at authorized Agent Stations including radio voter results. At the Agent Station, automatic transmitter selection can be overridden by the Agent. The Agent can also create groups of unselected channels for background monitoring.

The EmVista Central System also includes an integrated interface to a B&C Transit Public.

SEPTA South Eastern Pennsylvania Transportation Authority

VoIP EmVista Central

The SEPTA (South Eastern Pennsylvania Transit Authority) configuration consists of hundreds of analog phone ECBs (Emergency Call Boxes) located at patron stations throughout Philadelphia that are connected to a Command Center via a Centrex phone system. At the Command Center, the calls are received by IP gateways and presented to robust VoIP EmVista Central servers. The servers connect incoming calls to Transit Police Agent Stations on the VoIP network. The Agent Stations have been personalized with response/disposition screens for ease of tracking calls.

An EmVista Maintenance Station is also a part of the Command Center, Server/Agent Station network. The Maintenance Station has special testing modules for the unique ECBs and provides scheduled testing capability with resultant reports.

Recently, SEPTA has upgraded the system to eliminate the Centrex connection link and extend the VoIP network out to each station. The ECBs remain the same but are connected directly to the network using IP gateways.

End-to-end VoIP communications

Emcom Systems has provided its EmVista Central System to implement the specified ICC (Integrated Communication Controller) and has supplied its IP6000 and IP6030 IP phones as the emergency communications endpoints. The system utilizes end-to-end VoIP communications and Emcom Systems has provided endpoint connections to the radio system, to the PSTN and to Cisco Call Manager as well as an Agent Station screen interface to the GEisys PA/VMS system.

All of the disparate voice streams are presented at Agent Stations for call monitoring and/or management. Calls to these endpoint devices are made either by clicking on an Agent Station screen object or by dragging and dropping the screen object onto an active call screen area.

Incoming calls are immediately presented at all Agent Stations and may be answered by one agent or shared between agents. Connections can be made between radio, phones and PA either by Agent Station management or by access codes from specified endpoints.

The system is extremely resilient with 3 robust servers available to handle communications. There is no performance loss if one server fails and only non-critical services are reduced should a second server fail. In addition, at extremely critical communication areas along the rail link, small EmVista Local servers are used to provide yet another level of redundancy.

The IP6000 IP phones provide patron emergency communication while the IP6030 IP phones provide emergency and maintainer communication along the rail link. Each IP6030 units is colocated with an A400 Speaker/Beacon. The beacon flashes when a call is made to or from a unit and calls to a unit are loudly annunciated by the speaker. In addition, announcements can be made to groups of speakers either directly from any IP6030 unit or from any Agent Workstation.

The setup interface point for the EmVista Central System is an EmVista Maintenance Station. From this station, all of the endpoint devices are managed and entered into the system database. Periodic testing of endpoints and endpoint connections is also performed by the Maintenance Station.
