NOTES:

1. The pANI is used as the Called party number. In BellSouth the MSC MUST use dedicated

trunks to the Emergency Services Network Entity (ESNE) to route the Emergency Services
Call (ESC).

2. The Generic Digits Parameter IS NOT ALLOWED TO BE SENT IN THE IAM WHEN

USING WRLS_CLD!

3. The Calling Party Number MUST be included in the IAM message. The Charge Number may

also be included in the IAM, but if so it MUST be the SAME as the Calling Party Number.
Although Charge Number Parameter is allowed as an optional parameter, it is ignored by the
NDET when using either of the WRLS_xxx signaling options.
