5. Select 4) Advanced Options.
6. Configure the options as described in Table 42 on page 98.
Table 42: CTP Bundle Advanced Port Option Settings in the CTP Menu
Your ActionFunctionField
Select y or n.Do not change this value without
consulting JTAC.
Specifies whether or not the CTP device
drives received data (RD) onto data set
ready (DSR) and real-time (RT) data
onto test mode (TM).
Single ended data/clock outputs
Select y or n.Do not change this value without
consulting JTAC.
Specifies whether or not to reclock RD
with the RT clock to align the data and
the clock.
Reclock RD to align RD/RT
Select y or n.Specifies that the CTP device disqualifies
transmit timing (TT) only when it is higher
than the port speed.
When enabled, this setting keeps the port
from going to the TtFail state when the
incoming user clock fluctuates between
0 and the configured port rate. If the TT
rate goes above the configured port rate,
the CTP device sends the port to the
TtFail state to protect the system from
an overspeed TT, which would cause
problems for the port, CTP device, or
network.
Only high TT checking
Select y or n.When request to send (RTS) is inactive,
specifies whether or not the CTP device
feeds TT with the internally created
clock.
TT Clock Gated by RTS
Select y or n.When clock gating is enabled, specifies
whether or not to use the inverted RTS
signal.
RTS Clock Gate Invert
Select y or n.Specifies whether or not to invert data
bound for the interface with data bound
for the IP network.
Input/Output Data Invert
Select y or n.Helps maintain the low-speed port on a
TDM/TDC CTP serial circuit at up when
the high-speed circuit goes down.
Substitute DDS when TT gone
