13.2 Internal/External Protocol Stacks and Text Messaging

WCDMA networks support concurrent internal/external protocol stack services and
text messaging.
When data is transmitted using the external protocol stack, text messages can be
sent through only the ports on which no data is being transmitted.
When the internal protocol stack is in use, text messages can be sent through all
ports in non-transparent transmission mode and through only the USB in transparent
transmission mode.
Table 13-1 describes the details.
