Alternatively, the internal time-slot assignment
counters and comparators can be used to access
anytime-slotinaframe,usingtheframesyncinputs
as markerpulses for the beginningof transmit and
receivetime-slot0. In this mode, a framemaycon-
sist ofup to64 time-slotsof 8bitseach.A time-slot
is assignedbya2-byteinstructionasshownintable
1 and6. The last6 bits of the secondbyte indicate
the selected time-slot from 0-63 using straight bi-
nary notation. A new assignment becomes active
on the second frame following the end of the Chip

TRANSMIT GAIN INSTRUCTION BYTE2
The transmit gain can be programmed in 0.1 dB
steps by writing to the Transmit Gain Register as
defined in tables 1 and 7. This corresponds to a
range of 0 dBm0 levels at VF
X
I between 1.619
Vrms and 0.087 Vrms (equivalent to + 6.4 dBm to
– 19.0 dBm in 600
).
To calculate the binary code for byte 2 of this in-
struction for any desired input 0 dBm0 level in
Vrms, take the nearest integer to the decimal
number given by :
and convert to the binary equivalent.Some exam-
ples are given in table 7.
