Procedure 4-16: Install LNW80 switch pack

- Overview

Use this procedure to install LNW80 Switch circuit packs in Main slots M1 and M2.

The LNW80 Switch circuit pack has no optics and is used in headless main applications to allow full use of the VT1.5 switch fabric for VT1.5-type hairpin cross-connections. The LNW80 circuit pack supports equipment-related alarms.

The LNW80 Switch circuit pack requires no provisioning and does not support loopbacks, test access, performance monitoring, DCC functionality, incoming signal alarms, line timing, DS1 synchronization outputs, and upgrades. The LNW80 Switch circuit pack cannot be a cross-connection source or destination.
