For Release 6.0 systems, Remote Call Forwarding can be used in combination
with Caller ID on a loop-start PSTN line connected to a networked system’s 800
LS-ID line/trunk module (loop-start ID delay must be on). To pass Caller ID
information across the network when a call is transferred, set the Remote Call
Forwarding Delay to one ring. Transfer of the call must be completed before the

CAUTION:
!
Unless networked systems are co-located, each system should have at
least one loop-start line connected to the PSTN. The line is required to allow
connection of a power-failure telephone to the Power-Failure Transfer (PFT)
jack on a module as a power outage backup and for correct routing of
emergency and other N11 calls. To ensure that the correct services are
reached, if the loop-start line is used for emergency or other N11 calls, it
