Programming Information
IDT82P2281
Bit Name
Default
Bit No.
Type
This bit is valid when the CRC Multi-frame or the Modified CRC Multi-frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert all 4 calculated CRC bits in one Sub-Multi-Frame.
This bit is cleared when the inversion is completed.
This bit is valid when the CRC Multi-frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert one 6-bit CRC Multi-Frame alignment pattern (‘001011’).
This bit is cleared when the inversion is completed.
This bit is valid when the CAS Multi-frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert one 4-bit Signaling Multi-Frame alignment pattern (‘0000’).
This bit is cleared when the inversion is completed.
This bit is valid when the Basic frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert one NFAS bit (the Bit 2 of TS0 of each odd frame).
This bit is cleared when the inversion is completed.
This bit is valid when the Basic frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert one 7-bit FAS pattern (the Bit 2 ~ Bit 8 of TS0 of each even frame).
This bit is cleared when the inversion is completed.
This bit is valid when the Basic frame is generated.
A transition from ‘0’ to ‘1’ on this bit will invert one FAS bit (the Bit 2 ~ Bit 8 of TS0 of each even frame).
This bit is cleared when the inversion is completed.
