For example, the code numbers 01, 02, ..., were prepended to the dialed string in 
the originating switch. For each line number, the code number is entered in the 
Search Digits field (as in the display above) as a unique digit string associated 
with the line number. Since the code number is not intended to be routed to the 
DEFINITY to complete...

Procedures for Extension Dialing Between Sites
These procedures outline two different extension dialing configurations that may be 
used from a particular site to other IP Trunk sites. The first configuration is non-DCS, 
where one trunk group exists in DEFINITY and is routed through the IP Trunk server 
to many different IP...

In Switch A above, the IP Trunk servers originating entries will be as follows, in 
order for calls through that IP Trunk server to be routed to Switch B and Switch C 
appropriately.
These entries allow any line/port on the IP Trunk server to carry calls to the other two 
locations. It also allows each unique string (extension...

DCS over IP Trunk
IP Trunk supports most of the DCS features. DCS signaling with IP Trunk can be 
either X.25 or TCP/IP. For X.25 DCS signaling, the signaling data path is over a tie 
trunk connection between the switches. For TCP/IP DCS signaling, the signaling data 
is handled by the C-LAN circuit pack and can be either point-to-point (ppp) across a...

TCP/IP signaling
For TCP/IP signaling, you administer the connection on the Data Module screen and 
the Processor Channel Assignment screen. The data module type is 
ppp for a 
point-to-point signaling connection or 
ethernet for signaling over an IP network.
In addition, TCP/IP signaling requires administration of the Node Names screen and, 
in some...

These entries allow a specific line/port on the IP Trunk server to carry calls to a 
specific other location. No digits are searched for, as we already know that the 
DEFINITY has done the appropriate digit analysis. A unique string is applied in front 
of each dialed string by adding a replace string; each replace...

When a call terminates on a line, we search for the unique string associated with that 
line, but we do not replace it. This reforms the digit string back to the way it left the 
originating DEFINITY, and passes the appropriate digits to the DEFINITY at the 
terminating end.Line Search

Rerouting calls when IP transmission quality is poor
When transmission quality over the IP network is unacceptable, use AAR or ARS 
with Configuration Manager to reroute calls over private and public telephone 
networks. This is called PSTN Fallback.
Before you startBefore you perform this procedure, complete the following tasks:
•Plan call routing...

More informationThe Packet Loss Threshold and Round Trip Delay Threshold fields work like this:
If the value in either High field is exceeded, access to the IP trunk group is 
blocked.
Access to the IP trunk group is only allowed again when the average for both 
measurements drops below the values in the Low field.
