TMUX03155 STS-3/STM-1 (AU-4) Multiplexer/Demultiplexer
Transmit Direction Overview
The following major functions are performed in the transmit direction: STS-1/AU-3 bus mode retiming, input select
control, STS-1/AU-3 inputs, out-of-frame (OOF) and loss-of frame (LOF) monitoring, descramble enable/disable,
monitor B1 and B2 errors, H4 multiframe and pointer monitor (AU-4 mode only), STS-3 generate, STM-1 (AU-4)
frame generation (AU-4 mode), transport overhead access channel (TOAC) insert, STS-3/STM-1 (AU-4) scramble
enable, STS-3/STM-1 (AU-4) loopback control, and STS-3/STM-1 (AU-4) output interface.
STS-1/AU-3 Bus Mode Input Retiming
The bus mode provides a single byte-wide bus and parity bit that is shared with up to three devices at
19.44 Mbits/s. The device will source a clock (19.44 MHz), synchronous payload envelope (SPE) indicator, J0J1V1
indicator, and V1 time indicator signals toward the downstream devices. These signals guarantee frame alignment
between all three STS-1/AU-3 inputs and H4 byte multiframe values (AU-4 mode). The V1 time signal can be dis-
abled under software control (
TLSV1DISABLE, 0x35
).
The clock can be inverted leaving the device (
TLSCLKINV, 0x35
). An odd/even parity bit (
TLSVOEPAR, 0x35
) is
verified per byte transfer (
TLSPARE[3—1],
TLSPARM[3—1], 0x07, 0x10
).
Input Select Control
This function determines which signals are multiplexed to form the STS-3 signal. These control bits (
TSEL[3—
1][2:0], 0x3A, 0x38, 0x36
) allow loopback (STS-1/AU-3-R to STS-1/AU-3-T), input shuffle, and multicast opera-
tions to be possible. The selected STS-1/AU-3 inputs are labeled S#1T, S#2T, and S#3T in Figure 1.
STS-1/AU-3 Inputs
The SONET/SDH STS-1/AU-3 frame is comprised of 9 rows x 90 columns that repeat at an 8 kHz rate. Each col-
umn is 1-byte wide. The frame contains three columns of transport overhead, one column of path overhead, and
86 columns of payload. For column byte definitions, see Table 6 on page 18.
