Configuring Advanced Port Options for CTP Bundles (CTP Menu)

Before you begin:

  • Disable the bundle before you modify the bundle options.

To configure advanced port options for CTP bundles using the CTP Menu:

  1. From the CTP Main Menu, select 1) Bundle Operations.
  2. Select 1) CTP.
  3. Select a bundle from the list.

    If you select an active bundle, you are prompted to disable the bundle before configuring it.

  4. Select 3) Port Config.
  5. Select 4) Advanced Options.
  6. Configure the options as described in Table 42.

Table 42: CTP Bundle Advanced Port Option Settings in the CTP Menu

FieldFunctionYour Action

Single ended data/clock outputs

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).

Select y or n.

Reclock RD to align RD/RT

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.

Select y or n.

Only high TT checking

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.

Select y or n.

TT Clock Gated by RTS

When request to send (RTS) is inactive, specifies whether or not the CTP device feeds TT with the internally created clock.

Select y or n.

RTS Clock Gate Invert

When clock gating is enabled, specifies whether or not to use the inverted RTS signal.

Select y or n.

Input/Output Data Invert

Specifies whether or not to invert data bound for the interface with data bound for the IP network.

Select y or n.

Substitute DDS when TT gone

Helps maintain the low-speed port on a TDM/TDC CTP serial circuit at up when the high-speed circuit goes down.

Select y or n.
