List of terms

XNTP

A Nortel Multiservice Switch system feature that controls the setting of network time.

xPD

A generic term for any of a number of packet discard algorithms (for example, EPD, PPD, WRED).

Y-Protection

A Y-protection configuration enables two matched fiber optical FPs to have hitless equipment protection (EP) and hitless software migration (HSM) while the far-end interface does not support automatic protection switching (APS) or multiplex section protection (MSP). The capability is achieved through software control of hardware lasers firing through custom-made cable assemblies that split the transmit and receive signals to and from the pair of FPs to a single interface.

Y-splitter cable

A Y-splitter cable is a fiber optical cable with each transmit and receive fiber physically split into two. A pair of duplex single-mode (SM) Y-splitter cables is required for each pair of ports on a pair of Nortel Multiservice Switch 15000 or Multiservice Switch 20000 node function processors (dual FPs) that are configured in software to use Y-protection.
