Each Transmit Signaling Register (TS1 to TS16) con-
tains the CAS bits for two timeslots that will be inserted
into the outgoing stream if enabled to do so via TCR1.5.
On multiframe boundaries, the DS2154 will load the val-
ues present in the Transmit Signaling Register into an
outgoing signaling shift register that is internal to the
device. The user can utilize the Transmit Multiframe bit
in Status Register 2 (SR2.5) to know when to update the
signaling bits. The bit will be set every 2 ms and the user
has 2 ms to update the TSR’s before the old data will be
retransmitted. ITU specifications recommend that the
ABCD signaling not be set to all zeros because they will
emulate a CAS multiframe alignment word.
The TS1 register is special because it contains the CAS
multiframe alignment word in its upper nibble. The
upper nibble must always be set to 0000 or else the ter-
minal at the far end will lose multiframe synchronization.
If the user wishes to transmit a multiframe alarm to the
far end, then the TS1.2 bit should be set to a one. If no
alarm is to be transmitted, then the TS1.2 bit should be
cleared. The three remaining bits in TS1 are the spare
bits. If they are not used, they should be set to one. In
CCS signaling mode, TS1 to TS16 can also be used to
insert signaling information. Via the SR2.5 bit, the user
will be informed when the signaling registers need to be
loaded with data. The user has 2 ms to load the data
before the old data will be retransmitted.
Via the CCR3.6 bit, the user has the option to use the
Transmit Channel Blocking Registers (TCBRs) to deter-
mine on a channel by channel basis, which signaling
bits are to be inserted via the TSRs (the corresponding
bit in the TCBRs=1) and which are to be sourced from
the TSER or TSIG pin (the corresponding bit in the
