Transmit Multiframe Alignment
Bits One to Four. These bits are
transmitted on the PCM 30 2048
kbit/sec. link in bit positions one to
four of time slot 16 of frame zero of
every signalling multiframe. These
bits are used by the far end to
identify
signalling multiframe. TMA1-4 =
0000 for normal operation.
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit position
five of time slot 16 of frame zero of
every multiframe. X1 is normally
set to one.
This bit is transmitted on the PCM
30 2048 kbit/sec. link in bit position
six of time slot 16 of frame zero of
every multiframe. It is used to
indicate the loss of multiframe
alignment to the remote end of the
link. If one - loss of multiframe
alignment; if zero - multiframe
alignment acquired. This bit is
ignored when AUTY is zero (page
01H, address 11H).
These bits are transmitted on the
PCM 30 2048 kbit/sec. link in bit
positions
respectively, of time slot 16 of
frame zero of every multiframe. X2
and X3 are normally set to one.

Table 17 - HDLC Selection Word
(Page 01H, Address 14H)
HDLC0 Select. If one, then HDLC0
is connected to the data link on
selected S
16 or 20 kbits/sec. If zero, HDLC0 is
deselected and all HDLC0 interrupts
are masked.
HDLC1 Select. If one, then HDLC1
is connected to time slot 16 in CCS
mode. If zero, HDLC1 is deselected
and
masked.
Receive Transparent Mode. When
this bit is set to one, the framing
function is disabled on the receive
side. Data coming from the receive
line passes through the slip buffer
and drives DSTo with an arbitrary
alignment. When zero, the receive
framing function operates normally.
Unused.
