17.48. NORR - No rerouting with LCR 
Feature:
LCR rerouting
Function:
COT parameter NORR can also be used to influence the LCR rerouting administered by
the AMOs
RICHT and LDAT during an outgoing trunk seizure.
If the NORR parameter is set in the COT of a trunk, then LCR rerouting is generally
deactivated for outgoing seizures of a trunk and the functions of the TGRE COT parameter
-
control LCR rerouting on the basis of cause values - are ignored.
If, on the other hand, the NORR is not set in the COT of a trunk, LCR rerouting is
always
carried out for outgoing seizures of a trunk and the functions of the COT parameter
TGRE -
control LCR rerouting on the basis of cause values - are taken into account.
IMPORTANT:
An outgoing seized analog tie trunk circuit or trunk which does not
receive an analyzed dialing party from the partner system is through-connected if
the NORR
parameter is set. For this reason, the NORR parameter should always be set for these
trunk
types if LCR rerouting is administered.
AMO Interrelationships:
COT Class of Trunk
TGRE - Control LCR rerouting the basis of cause values
Device types:
Analog and digital CO trunk circuits, interface circuits and tie trunk circuits
For example, SOCOD, S2COD, SOCONN, S2CONN - MOSIG Main station code, DP Dial pulse
code
