Call to Non-Local Extension: Warble Tone (Error Tone)
Check to make sure the calling restriction of the default COR is set to
unrestricted. The factory setting is outward restricted, which blocks calls
across the private network.
Check that the routes voice/data capability is correct for the type of call
being made. The factory setting is Both, which will support both voice
and data calls.
In each intervening system, compare the FRLs assigned to routes
for the call with the default COR FRL. The route FRL must be
equal to or lower than the default COR value or the call is
blocked. The factory setting is 3.
If FRL settings are not the cause, go to Possible Cause 9.
Possible Cause 9: If the call is a 64-kbps data call, all routing facilities may not
support this data speed.
What to Do: Unless you are directly connected to the destination system, the
coordinating system manager must check the routes for the call. To check the
local routes, see "Reviewing the Non-Local Dial Plan and Routing" in Chapter 6
of Network Reference . To change the routing in order to specify facilities that
can handle the call, see "Uniform Dial Plan Routing" in Chapter 5 of Network
Reference , or "UDP Routing" in Chapter 3 of System Programming.
If the call is routed over any analog facilities (tie or loop-start, for example),
T1-emulated voice or data facilities, it cannot go through. If the call is routed
over PRI and/or BRI facilities, a speed of 64 kbps may be possible. If this is not
the cause of the problem, call the Lucent Technologies Helpline at 1 800
628-2888; consultation charges may apply.
Call to Non-Local Extension:
Warble Tone (Error Tone)
There are several reasons why a call to a non-local extension receives warble
tone. The first two possibilities are easy to check, because they all derive from
