C-18ADMINISTRATIVE PROCEDURE SUMMARY

In addition, a thousands digit can be assigned in field 4. This digit must be assigned in 3-digit switches for the calling party number and connected number to make sense. If assigned in a 4 or 5- digit switch, it is used for the thousands digit in the address digit stream regardless of what the thousands digit is for the extension or LDN.

Calling-party number IE Opcode: 6C (assuming no codeset mapping in Generic 2) Numbering plan identification: telephony numbering plan (The exception to this is in Generic 2 on a BRI-to-BRI call within the switch where Private Numbering Plan is used)

Type of address: national number (The exception to this is in Generic 2 on a BRI-to-BRI call within the switch where Unknown is used.) The 10 address-digit octets follow the above information.

PROCEDURE 420 (System 85 R2V4 & Generic 2)

Type-2 data can be useful in determining which regular tasks are using an abnormally high amount of processor time. The data in field 3 of this procedure multiplied by 100 is the number of times this task has been interrupted by the 10-ms interrupt. An unusally high number in field 3 (compared to the other regular tasks) shows that the task number in field 2 is currently a processor-occupancy hog. This condition is normally an error condition and can point to problems with the feature controlled by the regular task.
