(Monitor Receive) bit are used for handshaking functions for Channel A  
and B. Both MX and MR bits are active low .  
In compressed operation, two GCI time slots are required to access  
the four channels of IDT821064. The GCI time slot assignment is  
determined by S1 and S0 as shown in Table 1.  
Other four GCI time slots are used for linear voice data (a 16-bit 2’s  
complement number, b15 and b14 are the same as b13, which is the  
sign bit, b13 to b0 are effective bits). Each GCI time slot consists of two  
16-bit linear voice data bytes: one byte contains the linear voice data for  
Channel A, the other byte contains the linear voice data for Channel B.  
The GCI time slot assignment is determined by S1 and S0 pin. When  
S0 and S1 are both low, the linear GCI Frame Structure is shown in  
Figure 2.  
LINEAR GCI MODE  
In GCI linear mode, one GCI frame consists of 8 GCI time slots, each  
GCI time slot consists of four 8-bits bytes. Four of the 8 GCI time slots  
are used as Monitor Channel and C/I octet, they have a common data  
structure:  
- Two don’t_care bytes.  
In linear operation, because one chip of the four-channel IDT821064  
occupies four GCI time slots ( two for voice data and two for C/I and  
monitor), the rest four GCI time slots can be used by other device. There  
are four locations in the 8-time-slots GCI bus for one IDT821064 to select,  
see Table 2.  
- One Monitor Channel byte, which is used for reading/writing control  
data/coefficients from/to the device for Channel A and B.  
- One C/I byte, which contains a 6 bit width C/I channel sub-byte together  
with an MX bit and an MR bit. All real time signaling information is carried  
on the C/I channel sub-byte. The MX (Monitor Transmit) bit and MR
