How cer works

How CER Works

  • Retrieves phone information from Communications Manager

  • Retrieves phone location/port info from switches

  • Maps port/phone to ERL

  • Maps ERL to gateway to route outbound 911 calls

  • Routes PSAP call back to calling party

  • Notifies UCAR security via web, email, phone for all 911 calls.

Ncar s 911 call routing

NCAR’s 911 Call Routing

  • 9911 – Call routed directly to PSAP, NCAR security also notified

  • 1911 – Call routed to NCAR security, PSAP not automatically notified

  • 911 – Call routed to NCAR security, PSAP not automatically notified


What nets needs to remember

What NETS needs to remember

  • Port labels in switches need to be correct. This information is used by emergency services personnel to locate the caller.

  • IPT team adds new switches to CER. This allows CER to track phones.
