\ \(em\ The User Service Information parameter carries the customer's bearer service request unchanged through the network, and is mapped at the terminating exchange. Transmission Medium Requirements maps from the service request to a network connection type. It is not mapped at the terminating exchange in an
ISDN call. For calls between networks (e.g. international gateways), the
contents of the Bearer Capability information element carried within the User Service Information parameter may be changed, e.g. where A\(hylaw to mu\(hylaw
conversion applies.

\ \(em\ The calling party number is recommended to be carried in the IAM,
however it may optionally be delayed until a subsequent end\(hyto\(hyend request in the network. Number and subaddress should be carried in the same message.

\ \(em\ The Keypad Facility information element may be used to carry called party number information in the user\(hyto\(hynetwork direction (described in \(sc\ 5.1 of Recommendation Q.921) rather than the Called Party Number information
element. This is then mapped to the Called Party Number parameter within the
network.
