Configuring ISUP for the Japan-NTT variant

Follow these guidelines when configuring the ISUP layer for Japan-NTT network operation:

  PC_FORMAT       JNTT

This statement tells the ISUP configuration utility to treat all subsequent point codes as mcode.scode.ucode format and generate 16-bit internal point codes with the U-code in the most significant seven bits, the S-code in the next four bits, and the M-code in the least significant five bits.

Note: The Japanese TTC variant is supported with the JNTT setting and the Global Messaging Toolkit.
