A.9.1

Call Scenario 1: ESRK Delivery

Call Scenario 1 describes the mode where an MSC uses ISDN User Part (ISUP) protocol to send an
ESRK to an E911 selective router. Call Scenario 1 supports the Wireline Compatibility Mode

1

described

in J-STD-036-A, Annex D, Section D.1.1. Wireless carriers can use Call Scenario 1 to support Phase I
and/or Phase II wireless E911 calls. The table below shows the possible alternatives for populating the
parameters in the Initial Address Message (IAM).

NOTES:

1. This ISUP parameter option is widely supported in the U.S. It is estimated that 95% of the

E911 selective routers deployed in the U.S. support this option when the selective router has
been equipped with wireless E911 features.

2. "Blank"-- this parameter MUST NOT be populated.

A.9.2

8.2 Call Scenario 2: CBN and ESRD Delivery

Call Scenario 2 describes the mode where a MSC uses ISUP protocol to send the caller’s CBN and
ESRD to an E911 selective router. Call Scenario 2 supports the Phase 2 NCAS

2

mode described in

J-STD-036-A, Annex D, Section D.1.2. Wireless carriers can use Call Scenario 2 to support Phase I
and/or Phase II wireless E911 calls. The table below shows the possible alternatives for populating the
parameters in the Initial Address Message (IAM).

1

J-STD-036 uses the term "Wireline Compatibility Mode" to describe scenarios where MSCs use the ISUP parameter mappings

normally used by landline switches to signal E911 calls to E911 selective routers.

2

J-STD-036 uses the term NCAS to describe scenarios where an MSC uses ISUP protocol to send CBN and ESRD to an

E911 selective router.
