In T1 modes, only Pack6 is applicable. In E1, unformatted mode cannot be used if

FAS_MFAS_CAS receive framing is configured. The only data processing performed during

unformatted mode is the alignment of transmitted data bits with respect to the receive and

transmit multiframe. Please see the valid modes for Pack8 and Pack6 in the table shown below.

00 = HDLC with FCS

01 = HDLC without FCS

10 = Unformatted Pack8

11 = Unformatted Pack6

The following initializations are required when Pack8 or Pack6 is selected:

If (Dlink mode == Pack8 or PACK6)

{

DL_TEST[1]

= 0x03

** The value DL_TEST[1] = 0x2 is for DLINK#1,

and 0x3 is for DLINK#2.

TEST

= 0x02

DL_TEST[5]

= 0x60

** DL_TEST[4] is for DLINK #1

DL_TEST[5]

= 0x10

** DL_TEST[5] is for DLINK #2

TDL2

= 0x0

TDL2_EOM

= 0x0

TEST

= 0x0

}
