Trunk Optimization (Before Answer)
EuroISDN Trunk - Network Side
Trunk Optimization is not supported across a EuroISDN Trunk - Network
Side interface. Trunk Optimization Before Answer is not supported within an
MCDN network, if the call originated from a EuroISDN Trunk - Network
Side connectivity interface.
Network Call Forward by Call Type (NCFCT)
For calls containing CLID in the setup message, the RCLS prompt is
superseded by the numbering plan type identified within the setup message.
Incoming trunk calls answered at node A, prior to entering the TIE trunk link
using call modification, contain a CLID as a result of the call modification
and may result in Internal call treatment at the terminating node.
Refer to the Network Call Redirection discussion in this document. Be sure
to consider this feature when configuring your network.
Network Call Redirection (NCFAC, NCFNA, NHNT)
TRO-BA depends on Network Call Redirection (NCRD) messages over the
D-channel. Be sure to allow NCRD for all routes targeted for TRO-BA calls.
When a call is redirected using TRO-BA, the redirection information is
passed to the originating node, the redirection is suspended, and a direct
connection is established. If a route is not available when the call is placed,
the call may be blocked.
Network Call Transfer
Trunk Optimization does not operate for Network Call Transferred calls.
Station and attendant extended calls do not utilize TRO-BA.
Network Message Service
TRO-BA occurs when Meridian Mail Call Sender is activated. No
optimization takes place when through dialing or operator revert features are
used, because the calling DN is not provided to Meridian Mail with these
features. When a call is optimized, the original called party information is
included in the setup message of the call. This is the way Meridian Mail
determines the intended receiver.
TRO-BA is packaged as an ISDN feature in Advanced Network Services
(NTWK) package 148.
