Appendix F – Embedded Control Characters - 17
Appendix E – Extended ID Processing
The WaveWare TAP interface and both COMP2 interfaces support ID field lengths from 1 to 10 digits. The ID
field can be formatted as follows:
Standard Method - ID field lengths from 1 to 4 digits will cause a pager database lookup. ID fields of
this format must contain numeric digits only. The numeric ID value will be compared to the ID values
stored in the
WaveWare Paging System ’s onboard pager database.
Extended ID Method - ID field lengths from 5 to 10 digits will cause Extended ID processing.
Extended ID processing assumes that the last 3 digits of the ID field define paging message encoding
attributes, while the preceding digits define the pager capcode. Extended ID processing allows you to
avoid the process of configuring a pager database in the
WaveWare Paging System
Extended ID fields should be of the form:
CCCCCCCERF , where C represents the capcode, E represents Message Encoding Type, R represents RF data
rate, and F represents Function Code.
The Extended ID field can be represented in either numeric or alphanumeric format. All Extended ID fields must be
between 5 and 10 digits in length to cause the paging system to perform Extended ID processing. Incorrect
formatting of extended ID fields causes a <NAK> response combined with an explanation message.
CCCCCCC is a 2 to 7 digit numeric value representing a pager capcode. Leading zeroes are optional except in the
case of capcodes 8 and 9, which should be represented with at least one leading zero, e.g. 08 or 09.
E is the message encoding type, where “ 0 ” (zero), “ n ”, or “ N ” represent “numeric encoding”, and “ 1 ”, “ a ”, or “ A ”
represent “alphanumeric encoding”. The numeric values for E are provided to support numeric-only ID fields in
paging control software.
R
is the RF data rate, where “ 5 ” represents 512 bps, “ 1 ” represents 1200 bps, and “ 2 ” represents 2400 bps.
F defines the function code to be delivered, where “ 1 ” is function code 1, “ 2 ” is function code 2, “ 3 ” is function
code 3, and “ 4 ” is function code 4. A function code of “ 0 ” is also valid. A function code of “ 0 ” causes the default
function code for a particular Message Encoding Type (“ E ”) to be substituted. The default value for F is “ 4 ” when
the E value is “alphanumeric encoding”, and “ 1 ” when the E value is “numeric encoding”.
Following are valid example Extended ID fields causing Extended ID processing:
08A20 – Causes delivery of a standard (function code 4) alphanumeric message to capcode 0000008 at 2400 bps
08A24
– Same result as above
0008124
– Same result as above
0000008124
– Same result as above
11A53
– Causes delivery of an alphanumeric message with function code 3 to capcode 0000011 at 512 bps
0000011A53
– Same result as above
11N53
– Same result as above, but with numeric encoding
038N52
– Causes delivery of a numeric message with function code 2 to capcode 0000038 at 512 bps
