What happens when you call 9-1-1 on a cell phone

12

• Your call is routed to a cell

tower

• That tower will have multiple

antenna from a variety of

carriers

• Each antenna is assigned an

ESN (Emergency Service

Number)

• An ESN is a 3 digit number, that determines which PSAP

will handle your call. For example ESN #123 might be the

CHP. Whereas ESN #456 might be for Santa Barbara

PD.

SantaBarbaraCA.gov

• When a new

antenna is installed

a coverage map

shows that

anticipated

coverage of that

antenna

13

• A decision is made and the wireless service

providers are then instructed which ESN is

assigned to that tower

Transfers versus Optimal Routing

• The 9-1-1 wireless infrastructure in

California needs to be continually audited to

ensure the correct routing of 9-1-1 calls
