E1 FRMR Interrupt Indication 1 (053H, 153H, 253H, 353H, 453H, 553H, 653H, 753H)
ISMFPI:
ICSMFPI:
SMFERI:
When one or more bits do not match, a single CAS Signaling Multi-Frame alignment pattern error event is generated. During out of CAS Signaling
Multi-Frame synchronization state, the CAS Signaling Multi-Frame Alignment Pattern Error detection is suspended.
ICMFPI:
CMFERI:
or more bits do not match, a single CRC Multi-Frame alignment pattern error event is generated. During out of CRC Multi-Frame synchronization
state, the CRC Multi-Frame Alignment Pattern Error detection is suspended.
CRCEI:
received CRC-4 of the next received CRC Sub Multi-Frame, a single CRC-4 error event is generated. During out of CRC Multi-Frame synchronization
state, the CRC-4 Error detection is suspended.
Programming Information

Bit Name
= 0: The received bit is not the first bit of each CAS Signaling Multi-Frame.
= 1: The first bit of each CAS Signaling Multi-Frame is received.
This bit will be cleared if a ’1’ is written to it. It can not be updated during out of CAS Signaling Multi-Frame synchronization state
= 0: The received bit is not the first bit of each CRC Sub Multi-Frame.
= 1: The first bit of each CRC Sub Multi-Frame is received.
This bit will be cleared if a ’1’ is written to it. It can not be updated during out of CRC Multi-Frame synchronization state.
When Signaling Multi-Frame is synchronized, the received Signaling Multi-Frame alignment signals are compared with the expected one (‘0000’).
= 0: No CAS Signaling Multi-Frame Alignment Pattern Error event is detected.
= 1: The CAS Signaling Multi-Frame Alignment Pattern Error event is detected.
This bit will be cleared if a ’1’ is written to it.
= 0: The received bit is not the first bit of each CRC Multi-Frame.
= 1: The first bit of each CRC Multi-Frame is received.
This bit will be cleared if a ’1’ is written to it. It can not be updated during out of CRC Multi-Frame synchronization state.
When CRC Multi-Frame is synchronized, the received CRC Multi-Frame alignment signals are compared with the expected one (‘001011’). If one
= 0: No CRC Multi-Frame Alignment Pattern Error event is detected.
= 1: The CRC Multi-Frame Alignment Pattern Error event is detected.
This bit will be cleared if a ’1’ is written to it.
When CRC Multi-Frame is synchronized and the local calculated CRC-4 of the current received CRC Sub Multi-Frame does not match the
= 0: No CRC-4 Error event is detected.
= 1: The CRC-4 Error event is detected.
This bit will be cleared if a ’1’ is written to it.
Default
Bit No.
