Register Name:
GFISR
Register Description:
Global Framer Interrupt Status Register
Register Address:
0F9h
Bit # 7 6 5 4 3 2 1 0
Name — — — — — — — FIS1
Default 0 0 0 0 0 0 0 0
The GFISR register reports the framer interrupt status for the T1/E1 framer. A logic one indicates the framer has
set its interrupt signal.
Bit 0: Framer Interrupt Status 1 (FIS1).
0 = Framer 1 has not issued an interrupt.
1 = Framer 1 has issued an interrupt.
Register Name:
GBISR
Register Description:
Global BERT Interrupt Status Register
Register Address:
0FAh
Bit # 7 6 5 4 3 2 1 0
Name — — — — — — — BIS1
Default 0 0 0 0 0 0 0 0
The GBISR register reports the interrupt status for the T1/E1 bit error-rate testers (BERTs). A logic one indicates
the BERT has set its interrupt signal.
Bit 0: BERT Interrupt Status 1 (BIS1).
0 = BERT 1 has not issued an interrupt.
1 = BERT 1 has issued an interrupt.
Register Name:
GLISR
Register Description:
Global LIU Interrupt Status Register
Register Address:
0FBh
Bit # 7 6 5 4 3 2 1 0
Name — — — — — — — LIS1
Default 0 0 0 0 0 0 0 0
The GLISR register reports the LIU interrupt status for the T1/E1 LIUs. A logic one indicates the LIU has set its
interrupt signal.
Bit 0: LIU Interrupt Status 1 (LIS1).
0 = LIU 1 has not issued an interrupt.
1 = LIU 1 has issued an interrupt.
