PRS-CSRK Remote Call
Station Kit
21. 1
Introduction
The PRS-CSRK Remote Call Station Kit contains a
printed circuit board (PCB) that can be used to make
custom-made remote call stations (e.g. a remote
emergency call station). See figure 21.1 for a block
diagram of the remote call station kit.
The PRS-CSRK Remote Call Station kit replaces the
LBB4439/00 Remote Call Station kit. You can only use
the PRS-CSRK in combination with the PRS-CSI Call
Station Interface. You cannot use the PRS-CSRK in
combination with the (old) LBB4437/00 Call Station
Interface. You can only use the LBB4437/00 to connect
LBB4438/00 and LBB4439/00 remote call stations to
the system.
