Default
Bit 7: Receive AIS-CI Event (RAIS-CI) (T1 Only). Set when the receiver detects the AIS-CI pattern as defined in
ANSI T1.403.
Bit 6: Receive Signaling All-Ones Event (RSAO) (E1 Only). Set when the contents of time slot 16 contains fewer
than three 0s over 16 consecutive frames. This alarm is not disabled in the CCS signaling mode.
Bit 5: Receive Signaling All-Zeros Event (RSAZ) (E1 Only). Set when over a full MF, time slot 16 contains
all 0s.
Bit 4: Transmit Multiframe Event (TMF)
Bit 3: Transmit Align Frame Event (TAF) (E1 Only). Set every 250μs at the beginning of align frames. Used to
alert the host that the TR.TAF and TR.TNAF registers need to be updated.
Bit 2: Receive Multiframe Event (RMF)
Bit 1: Receive CRC4 Multiframe Event (RCMF) (E1 Only). Set on CRC4 multiframe boundaries; continues to set
every 2ms on an arbitrary boundary if CRC4 is disabled.
Bit 0: Receive Align Frame Event (RAF) (E1 Only). Set every 250μs at the beginning of align frames. Used to
alert the host that Si and Sa bits are available in the TR.RAF and TR.RNAF registers.
E1 Mode: Set every 2ms (regardless if CRC4 is enabled) on transmit multiframe boundaries. Used to alert
the host that signaling data needs to be updated.
T1 Mode: Set every 1.5ms on D4 MF boundaries or every 3ms on ESF MF boundaries.
E1 Mode: Set every 2ms (regardless if CAS signaling is enabled or not) on receive multiframe boundaries.
Used to alert the host that signaling data is available.
T1 Mode: Set every 1.5ms on D4 MF boundaries or every 3ms on ESF MF boundaries.
