17.73. TCC - Signal incoming calls on analog tie trunk circuits
as trunk calls 
Feature:
Different terminal call signals
Function:
The TCC COT parameter can be used to control different call signals on analog tie
trunk
circuits of the type DB_CP_DEVTYP_TMA_CONN.
TCC set:
Terminals are called with the call type " co/extended call ring EXTCO" administered
with
the AMO ZAND.
TCC not set
Terminals are called with the call type "Standard ring NORM" administered with the
AMO
ZAND.
AMO Interrelationships:
ZAND: TYPE=RNGTYPE COEXT (co/extended call ring), NORM (standard ring)
TYPE=ALLDATA EXTCO (co/extended call ring also for switched calls and consultations
from
trunk calls)
FEASU: TYPE=FREE, LM=RNG Ring discrimination
Device types:
Analog tie trunk circuits type DB_CP_DEVTYP_TMA_CONN
For example, TSILP Tie trunk circuit, DC loop with idle signal loop
Protocol variants:
Analog
