Selects Data Conditioning
These bits determines the type of data condition applying to input
PCM data.
2
1
0
0x0 = The input PCM data is unchanged.
0x1 = All 8 bits of the PCM channel data are inverted.
0x2 = The even bits of input data are inverted.
0x3 = The odd bits of input data are inverted.
0x4 = Data in User Code Register shown in Table 3-27 replaces the
input
data.
0x5 = BUSY FF code (0xFF)) replaces the input data.
0x6 = BUSY 0Vcode (0xD5) replaces the input data.
0x7 = BUSY TS (111#_####) replaces the input data; ##### is
Timeslot
number.
0x8 = BUSY 00 (0x00) replaces the input data.
0x9 = The A-law digital milliwatt pattern replaces the input data.
0xA = The m-law digital milliwatt pattern replaces the input data.
0xB = The MSB (bit 1) of input data is inverted.
0xC = All input data except MSB is inverted.
15

0xD = PRBS, QRTS/X + X +1.
0xE = The input PCM data bit are unchanged.
0xF = This is a D/E time slots. See receive Signaling data link select
register 12. (RS&DLSR)

Selects Type of Zero Suppression
These bits select the zero code suppression used.
00 = No zero code suppression is used.
01 = AT&T bit 7 stuffing is used.
10 = GTE zero code suppression is used. Bit 8 is stuffed in non-sig-
naling
frame. Otherwise, bit 7 is stuffed in signaling frame if the signal-
ing bit is
zero.
11 = DDS zero code suppression is applied.
