Function
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.
When request to send (RTS) is inactive, specifies whether or not the
CTP device feeds TT with the internally created clock.
When clock gating is enabled, specifies whether or not to use the
inverted RTS signal.
Specifies whether or not to invert data bound for the interface with
data bound for the IP network.
Helps maintain the low-speed port on a TDM/TDC CTP serial circuit
at up when the high-speed circuit goes down.
Specifies whether you want to enable or disable loss of signal (LOS)
detection for CTP bundles in a T1/E1 both-ended Y cable configuration
(hardware-based redundancy or software-based Y cable link
protocol).
Before you begin:
Disable the bundle before you modify the bundle options.
To configure advanced port options for CTP bundles using the CTP Menu:
From the CTP Main Menu, select 1) Bundle Operations.
1.
Select 1) CTP.
2.
Select a bundle from the list.
3.
If you select an active bundle, you are prompted to disable the bundle before
configuring it.
Select 3) Port Config.
