Lucent Technologies Release 8.2 Tandem switch information, Isdn numbering formats, Diversion

QSIG	B Private Networking
	Tandem switch information
	However, in the case of tandemed calls (calls involving two ISDN trunks that are not
	both administered for Supplementary Service Protocol B), trunk group administration
	may override both incoming name and number information, as long as doing so does
	not lower the restriction on the information. For example, a tandemed call that comes
	in with restricted name information is sent out with restricted name information even
	if the outgoing trunk is administered for presentation unrestricted. However,
	non-restricted data is sent restricted if the trunk group administration is set for
	“presentation restricted.”
	ISDN numbering formats
	Numbering is specified on the ISDN Public-Unknown-Numbering and/or ISDN
	Private-Numbering forms. The numbering form you use depends on how you
	administer the ISDN trunk group Numbering Format field.
	However, if you format the Called Party Number with public numbering, the
	Calling/Connected Party Number is created in the public format even if you specify
	“private” on the ISDN trunk group form. This provides the caller or called party a
	number that can be used to reach the other party. Since the call routes through the
	public network, the public Calling/Connected Party Number is a more accurate
	address.
Call Forwarding	Call Forwarding works over a QSIG network.
(Diversion)	When a call has already been forwarded 3 times over a QSIG trunk, it is not
	forwarded again but instead terminates at the final forwarded-to terminal. Remote
	activation and deactivation of this feature are not supported.
Call Transfer	QSIG Call Transfer is based on the current DEFINITY ECS Transfer and
	Trunk-to-Trunk Transfer features. QSIG Transfer signaling occurs as long as one of
	the calls involves a QSIG trunk between the two switches.
	Once a call is transferred, the transferring switch is unnecessary. Additional Network
	Feature-Path Replacement (ANF-PR) is invoked automatically to connect the
	transferred call more efficiently in the private network. QSIG Call Transfer attempts
	to connect the two parties more efficiently and drops the unnecessary switches.
	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 DCS Call Transfer in that additional call information
	is available for the connected parties after the transfer completes.
	Depending upon QSIG Identification Services administration, the connected parties’
	displays show each other’s name and/or number. If the name and number are not
	available, the display of a connected party updates with the name of the involved
	trunk group.
