forms to ISO 13869 for QSIG Call Transfer By Join. This m eans that the transfer
occurs through the system where the transferring user resides and if the transfer
involves two trunks, neither is released after the transferring party i s dropped
from the call.
When you use this feature, you see no difference between QSIG Call Transfer
and the standard DEFINITY ECS Transfer or Trunk-to-Trunk Transfer features .
QSIG Call Transfer differs from the standard DEFINITY ECS Transfer feature in
that additional call information is available for the conn ected parties after the
transfer completes. However, the information is only sent for QSIG trunks. If one
call is local to the transferring switch, that user rece ives the name of the party at
the far end.
QSIG Manufacturers SpecificInformation (MSI)
QSIG handles non-standardized information that is specific to a particular PB X or
network. This information is known as Manufacturer Specific Info rmation (MSI). A
manufacturer can define manufacturer-specific supplementa ry services opera-
tions after it has:
■Applied to a sponsoring and issuing organization (ECMA in this case)
ECMA: European Computer Manufacturers Association
■Been assigned an organization identifier. This organizatio n identifier is
used as the root of the manufacturer-specific service-oper ation value.
All MSI operation values should be unique to that manufa cturer.
In R6, a new information-transport interface allows applicat ions to hand-off
information for transport across QSIG networks via Manu facturer Specific
Information. It is highly likely that more than two applicat ions will need to send
information at the same time. Therefore, the limit has been increa sed to 4 for R6.
Manufacturer-specific supplementary services can be created using spe cific
operations encoded with the manufacturer’s identifier. For R6, support ha s been
added for non-QSIG applications to transport information across QSIG networks
in MSI. Applications now have the same functionality over QSIG networks that
they have over non-QSIG networks. An interface provide s application-specific
processing of the operations received. The default platform treatment i s to store
the information.
QSIG Name and Number Identification
Allows a switch to send and receive the calling number, calling na me, connected
number, and connected name. Additional parameters that control the displ ay of
the connected name and number are administered on the Feature-Re lated Sys-
