3.8.2 Explanation of DCA Service Displays

Data is always displayed in hexadecimal numbers. The Base Station number relates to the physical connection in the RE. Refer to Section 2, "System Description", Chapter 5, Paragraph 5.4, "Numbering Conventions" in this manual to find this relation.

Note:

A Portable Telephone is always blind for the two adjacent time slots. For example, a Portable Telephone is locked on a Base Station on time slot 5. If it approaches a Base Station that has only one active channel (traffic or beacon) on time slot 4 or time slot 6, the Portable Telephone will not see that Base Station. The display remains unchanged until the current channel or the channel of the second Base Station changes. Consider this when using the menus below.
