Lead Descriptions
Add Telecom Bus Timing Mode: Selects Master or Slave
timing mode on the Add Telecom Bus.
If CBADT is high, Slave timing is selected: CBADCLK, CBAD-
SPE and CBADJ0J1 are inputs.
If CBADT is low, Master timing is selected: CBADCLK,
CBADSPE and CBADJ0J1 are outputs.
Add Telecom Bus Data: Byte wide SDH/SONET data
received from the Add Telecom Bus.
Add Telecom Bus SPE Indicator: This signal is high during
each byte of the High Order Path Overhead and payload
bytes and low during the Transport Overhead byte times.
Add Telecom Bus J0J1 Indicator: This signal represents
the frame sync and optionally the position of each payload
container (VC-n/STS-N SPE). This signal works in conjunc-
tion with the CBADSPE signal. The J0 pulse identifies the
position of the first J0 byte when the CBADSPE signal is low.
The J1 pulses identify the position of the J1 byte of each pay-
load container (VC-n/STS-N SPE) when the CBADSPE signal
is high. A V1 pulse can optionally be available on this lead.
Add Telecom Bus Parity Bit: Parity bit input signal that rep-
resents the parity calculated over CBADD[7:0], and optionally
CBADSPE and CBADJ0J1. Even or odd parity can be
selected.
Add Telecom Bus Clock: This 77.76 MHz clock is used to
clock in Add Telecom Bus data.
In addition CBADSPE and CBADJ0J1 are clocked in in Slave
timing mode. CBADSPE and CBADJ0J1 are clocked out in
Master timing mode.
The active clock edges can be selected.
