Note: Bits that are underlined are read-only; all other bits are read-write.
Bits 0 to 6: T2/E2/G.747 Transmit Loss Of Frame Generation (LOFGn where n = 1 to 7). A zero to one
transition on this bit will cause the T2/E2/G.747 transmit formatter to generate enough framing bit errors to cause
the far end to lose frame synchronization. This bit must be cleared and set again for a subsequent set of errors to be
generated
.
MODE
FRAMING ERRORS GENERATED
T3 Mode
Four consecutive F bit errors
E3 Mode
Four consecutive FAS words of 0000101111 generated instead of the normal FAS word,
which is 1111010000 (i.e., all FAS bits are inverted)
G.747 Mode
Four consecutive FAS words of 000101111 generated instead of the normal FAS word,
which is 111010000 (i.e., all FAS bits are inverted)
Bits 8 to 11: E2 Transmit National Bit Setting (E2Snn where n = 1 to 4). These bits are ignored in the T3 and
G.747 modes. The received Sn can be read from the T2E2 Status Register 2.
0 = force the Sn bit to zero
1 = force the Sn bit to one
