Data Sheet
2.3.3
According to ITU recommendation I.430 a multi-frame provides extra layer-1 capacity in
the TE-to-NT direction through the use of an extra channel between the TE and NT (Q-
channel). The Q bits are defined to be the bits in the F
In the NT-to-TE direction the S-channel bits are used for information transmission. One
S-channel (S1) out of five possible S-channels can be accessed by the SCOUT.
The S- and Q-channels are accessed via the µC interface or the IOM-2 MONITOR
channel respectively by reading/writing the SQR or SQX bits in the S/Q channel registers
(SQRR, SQXR).
Table 9 shows the S and Q bit positions within the multi-frame.
