extension FRL. Similarly, if a caller is using ARS to call over another networked
system's PSTN facilities, the extension FRL is compared only with the local ARS
route and its value must be equal to or greater than the route FRL value. Once a
call arrives at a non-local system, the extension FRL has no effect. The remote
system compares the FRL for its default COR for tie or non-tie trunks with that of
the FRL of the next chosen route, as described in
Class-of-Restriction Settings" on page
Additional information about ARS is included in

many routing examples.
Barge-In
Barge-In does not work for calls on a non-local system in a private network.

Callback

Callback queuing works for lines/trunks connected to the caller's local system,
including private network tandem trunks. When a call is sent across the network
and a non-local system's trunks are busy, the caller cannot queue the call using
Callback.
When an extension has Automatic Callback turned on and originates a call to a
non-local extension, the call is queued at the local system for Route 1 only. If all
routes are busy, the caller hears callback tone. If the caller is using ARS or the
non-local dial plan to call out over trunks connected to a remote system and the
outside facilities at the remote system are busy, the caller hears the fast busy
tone. The caller hears the busy tone if he or she is calling a busy non-local dial
plan extension. Neither call activates callback queueing because the caller is not
connected to the system from which the busy condition originates.

Caller ID

If a call is routed on PRI tandem trunks from the receiving system to a non-local
extension, Caller ID information is also conveyed. If a Caller ID call is transferred
from the receiving system to the remote system, no Caller ID information is
conveyed.
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). The user at the extension that first receives the Caller
ID call from the PSTN turns Remote Call Forwarding on and specifies forwarding
across the network, over PRI tandem trunks only, to a non-local extension with an
2–6. In addition, Chapter 2, "Call-Handling Scenarios," includes
