Invert Transmit and Receive Data (9128)
Possible Settings: Enable, Disable
Default Setting: Disable
Specifies whether transmitted and received data for the synchronous data port is logically
inverted before being transmitted or after being received from the network. Use this
configuration option for applications where data is being transported using HDLC protocol,
whereby inverting the data ensures that the ones density requirements for the network are
met.
Display Conditions – This option only appears for Port-2 on a FrameSaver SLV 9128,
when Port Use is set to Synchronous Data.
Enable – Inverts the transmitted and received data for the port.
Disable – Does not invert the transmitted and received data for the port.
Action on Network Yellow Alarm (9128)
Possible Settings: None, Halt
Default Setting: Halt
Specifies the action to take on the synchronous data port when a yellow alarm is received
on the network interface. A yellow alarm indicates a problem with the signal being
transmitted to the network.
Display Conditions – This option only appears for Port-2 on a FrameSaver SLV 9128,
when Port Use is set to Synchronous Data.
None – No action taken when a yellow alarm is received.
Halt – Halts the transmission of data received on the synchronous data port and all ones
are sent on circuit BB (ITU 104) – Receive Data (RD) and circuit CB (ITU 106) –
Clear-to-Send (CTS) is deasserted to the port when a yellow alarm is received.
