This value must match the value set in the
other terminal. Note that this value must be
the same as the value programmed for the
packet size (G4 Parameter Switch 7, bits 0 to
3). Also, the transport block size is limited by
the amount of memory in the remote terminal.
Normally, do not change the default setting.
Do not change these settings.
When doing a back-to-back test or doing a
demonstration without a line simulator, use
these bits to set up one of the machines in TE
mode, and the other in NT mode
Please note that this machine can only be set
to TE mode.
After the test, return both bits to 0.
See "Back-to-back Testing" in the
Troubleshooting section for full details.
Do not change these settings.
