Page 2 Use loopbacks and hairpin circuits to test newly created SDH circuits before running live traffic or to logically locate the source of a network failure. All ONS 15454 SDH electrical cards, STM-N cards, G-Series Ethernet cards, MXP, TXP cards, and FC_MR-4 cards allow loopbacks and hairpin test circuits.

Page 4 1.1.1 Facility Loopbacks 1.1.1.2 ONS 15454 SDH Card Behavior ONS 15454 SDH port loopbacks either terminate or bridge the loopback signal. All ONS 15454 SDH optical, electrical, Ethernet, MXP, TXP, and FC_MR facility loopbacks are terminated as shown in Table 1-1.
Page 5 1.1.2 Terminal Loopbacks The following sections give general information about terminal loopback operations and specific information about ONS 15454 SDH card loopback activity. 1.1.2.1 General Behavior A terminal loopback tests a circuit path as it passes through the XC-VXL cross-connect card loops back from the card with the loopback.
Page 6 1.1.2 Terminal Loopbacks 1.1.2.2 ONS 15454 SDH Card Behavior ONS 15454 SDH port loopbacks can either terminate or bridge the loopback signal. In the ONS 15454 SDH system, all optical, electrical, Ethernet, MXP, TXP, and FC_MR facility loopbacks are terminated as shown in Table 1-2.
