10.24.4.2. AMO TDCSU (Digital), AMO TACSU (Analog ) Trunk Configuration 
With AMo's TDCSU and TACSU it is possible to define whether the
incoming trunk information is routed via a DIDCR table , a GDTR table
or no table selection, based on trunk and trunk group configuration parameters.
When configuring a digital trunk with AMO-TDCSU for ISDN-PRI or Cornet-NQ
trunks the new parameter TRTBL is used to select DIDCR or GDTR digit
conversion tables.
SIDANI= YES forces SID/ANI additional signalling to obtain the Called
Party (ANI) or Billing Party Information (SID/BN) if not presented in
original Call Setup message. If SID/ANI is required and not send by incoming
side the call will be released.
TGRP field is indirectly related for this feature to determine GDTR
Table rule index in the later stages of DNIS processing.
Digital Trunk configuration using AMO-TDCSU:
ADD-TDCSU:OPT=NEW,PEN=1-2-85- 0,COTNO=20,COPNO=20,DPLN=0,ITR=0,COS=1,LCOSV=1,LCOSD=1,CCT="NQ TEST",PROTVAR=ECMAV2,SEGMENT=8,TRTBL=GDTR,SIDANI=N,ATNTYP=TIE,DE V=S2CONN,BCHAN=1&&30,BCGR=1,TGRP=96;
This configuration forces GDTR conversion with no SID/ANI
requirement with using TGRP=96 for a Cornet-NQ trunk.
Analog trunk configuration using AMO-TACSU with TRTBL,RULEIDX, TGRP
(Example only)
ADD-TACSU:PEN=1- 1-121- 0,COTNO=240,COPNO=240,DPLN=0,ITR=0,COS=220,LCOSV=1,LCOSD=1,TGRP= 240,TRTBL=DID,RULEIDX=6,DEVTYPE=TT,DEV=TSEMCON;
This configuration uses DIDCR conversion table 6. AMO-BUEND
GDTRRULE has no effect.
