Insert Multiframe Alignment—The frame formatter outputs a 6-bit SF alignment pattern in T1
mode or a 6-bit MFAS alignment pattern in E1 mode. INS_MF should be set while TFRAME
(addr: 070) selects Fs (T1) or MFAS (E1) alignment.
Insert FEBE— During E1 mode, the alarm formatter automatically outputs TS0 bit 1 of
Frame 13 (FEBE13) and Frame 15 (FEBE15) in response to received CRC4 errors. FEBE13 is
active-low for each received CRC4 error detected in SMF I. FEBE15 is active-low for each
received CRC4 error detected in SMF II. INS_FE should be set while TFRAME (addr: 070)
selects FEBE (E1) alignment.
Insert Cyclic Redundancy Check—The frame formatter outputs the calculated CRC6 bits in
T1 mode or CRC4 bits in E1 mode.
Insert Terminal Framing—The frame formatter outputs a 2-bit Ft alignment pattern in
F-bits of odd frames (SF framing) or FPS framing pattern (ESF framing) during T1 modes—or
8-bit FAS/NFAS alignment pattern during E1 modes. INS_FBIT should be set while TFRAME
(addr: 070) selects Ft (T1, SF), FPS (T1, ESF), or FAS (E1) alignment.
