1+1 Protection on the Fiber Interface mode

The fiber transport is a 1+1 protection switched transport. It provides very fast (<50 mSec) switch-to-protect timing by transmitting the same information on both fibers at the same time. The fiber receiver then chooses the fiber to receive based on the validity of the line. Once the selection is made, the receiver will stay on that fiber line until it enters a fiber defect state at which time another fiber selection process is started (non-revertive switching). Once a switch-to-protect has occurred, a hold off time (1 second minimum) is used to prevent another switch-to-protect from occurring too soon after a protection switch.

If protection is not enabled, SFP port A will be used by default and no alarm or defect information will be provided for SFP port B. The LEDs associated with the backup fiber line will only be active if protection is enabled.

When protection is enabled, error reporting for the backup fiber line is limited to the Signal LOS condition. Signal LOS will generate an SFP Down trap.

A Remote Alarm Indication (RAI-F) signal is sent back to the fiber if the received fiber is in BER or LOS defect condition. In this way the far end unit is alerted of a fault condition on the local fiber line.

Console

The IE-iMcV-T1-Mux/4 + Ethernet includes a console serial port. To establish a link between a module's console port and a local PC, connect the Mini Jack to DB9 adapter (optional accessory available through IMC Networks, part number

825-39950). This RS-232 serial connection provides access to the IE-iMcV-T1-Mux/4

+Ethernet module CLI configuration screens. Set the computer/terminal for VT-100 emulation, 38.4K baud, 8 data bits, 1 stop bit, no parity and no flow control. Under the VT-100 emulation, set the backspace key to send delete.
