This is a fairly complex procedure requiring knowledge of routing commands. If you are not familiar with these, it's best to contact Altura for assistance. If you are, then use the "ass arsr" command to create route tables for long distance, local area code calls, and local calls. Then use the "ass arsc" command to include all known area codes that you expect to access. When assigning the area codes, if you have a range of area codes that share the first 2 digits, then you don't need to assign all three digits for the area code, i.e. hypothetical codes - 900,901,902...909; if each of these represented area codes that you would dial from your site, then you would assign the digits 90 in the area-code filed of the emml command to include all area codes starting with 90.
After the area codes are assigned, then use the "ass npco" command to tell the PBX how many digits are being sent to the Central Office. Typically, you send 10 digits for a directory number including the area, and office codes, so the number ten is put into the "EDL" field of the command.
You will need to know which route table number to use for long distance, local area code, and local dialing, as well as special numbers such as 911. You will also need to know how to use digit mainipulation commands to add or subtract trunk group access numbers such as 9 or 8 that are added or subtracted between networked PBX's. The feature implementation and command handbooks are invaluable in helping you to navigate this tricky part of F9600 programming.
All of this information is placed into the appropriate fields when using the EMML feature, rather than the command-line string. EMML makes this command a little easier to understand.
This information is by no means comprehensive. Much thought needs to be put into your dialing scheme to create properly operating ARSR and ARSC tables, not to mention digit manipulation tables. So be careful; and document everything before you start programming, and afterwords to enable you to troubleshoot any programming errors that may occur. Again, it's best to contact the experts rather than do this yourself, unless you are experienced with route table programming.
