Bits 0 to 6 / T2/E2/G747 Transmit Remote Alarm Indication (TRAIn where n = 1 to 7). When this
bit is set high in the T3 Mode, the X Bit will be set to zero. When this bit is set high in the E3 Mode, the
RAI bit (bit number 11 of each E2 frame) will be set to a one. In the E3 mode, TRAI5 to TRAI7 (bits 4
to 6) are disabled and should be set low by the Host. When this bit is set high in the G747 Mode, the RAI
bit (bit number 1 of Set 2 in each G747 frame) will be set to a one. When this bit it set low in the T3
Mode, the X Bit will be set to a one. When this bit is set low in the E3 and G747 Modes, the RAI bit will
be set to zero.
0 = do not transmit RAI
1 = transmit RAI
Bits 8 to 14 / T2/E2/G747 Transmit Alarm Indication Signal (TAISn where n = 1 to 7). When this
bit is set high, the transmit formatter will generate an unframed all ones pattern. When this bit it set low,
normal data is transmitted. In the E3 mode, TAIS5 to TAIS7 (bits 4 to 6) are disabled and should be set
low by the Host.
0 = do not transmit AIS
1 = transmit AIS

Note: Bits that are underlined are read only; all other bits are read-write.
Bits 0 to 6 / T2/E2/G747 Transmit Loss Of Frame Generation (LOFGn where n = 1 to 7). A 0 to 1
transition on this bit will cause the T2/E2/G747 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.
Framing Errors Generated
T3 Mode
4 consecutive F Bit errors
E3 Mode
4 consecutive FAS words of 0000101111 generated instead of the
normal FAS word which is 1111010000 (i.e. all FAS bits are inverted)
G747 Mode
4 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 G747 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
