Functional Description
No.
10 The condition in Item No. 9 has lasted for 100 ms.
11 Logic 1 is received in the A bit for a certain period. The criteria are defined in the
12 Logic 0 is received in any of the CRC error indication (E1 and E2) bits.
13 A logic 1 is received in the A bit and a logic 0 is received in any of the E1 and E2
14 A logic 0 is received in any of the E1 and E2 bits on ≥ 990 occasions per second
15 Logic 1 is received in the Y bit for 3 consecutive Signaling Multi-Frames.
16 The device is operating in the CRC to non-CRC inter working mode.
17 The position of the Basic Frame alignment pattern is changed.
18 The device is in the procedure of the offline Basic Frame searching.
19 The first bit of each Basic Frame is received.
20 The first bit of each CRC Sub Multi-Frame is received.
21 The first bit of each CRC Multi-Frame is received.
22 The first bit of each Signaling Multi-Frame is received.
23 2 out of 3 Sa7 bits are received as logic 0.
24 There is change in the corresponding SaX[1:4] (b3~0, E1-03DH).
7 The out of Basic Frame synchronization condition has lasted for 100 ms. (e.g., the
8 The calculated CRC remainder is not equal to the received C[1:4] bits.
9 It is out of Basic Frame synchronization and less than 3 zeros are detected in a
condition in Item No. 4 has lasted for 100 ms.)
512-bit stream, or it is out of Basic Frame synchronization and less than 3 zeros
are detected in each of 2 consecutive 512-bit stream. These two criteria are deter-
mined by the AISC (b1, E1-031H).
