Nortel Networks NN43001-106 Multi-Party Operations - Three-Party Service, Night Restriction Classes of Service

Feature interactions 301
If an analog (500/2500 type) telephone user attempts to set up a
Consultation connection by dialing a busy DN and if the Call Waiting
conditions are satisfied, the controlling party will hear ringback tone and
the active party will hear Call Waiting tone. If the controlling party goes
on-hook before the active party has answered, the held call is disconnected
regardless of the MPO options and Call Waiting tone is removed from the
active party.
Multi-Party Operations - Three-Party Service
An analog (500/2500 type) telephone cannot have Call Waiting during the
patience tone.
An analog (500/2500 type) telephone may be assigned both CWA and TSA
Classes of Service. The user can establish a Consultation connection by
answering Call Waiting during an active established call. If this is done,
Control Digit features (CNFD, TGLD, and DISD) are available. Note that
Programmable Control Digit TGLD, rather than a switchhook flash, is used
to toggle the calls. Operation with XFA Class of Service is unchanged.
The Three-party Service feature changes the operation of Call Waiting for
all analog (500/2500 type) telephones as follows (regardless of whether the
sets have TSA Class of Service. If an analog (500/2500 type) telephone
user activates Waiting during an active call so as to establish a Consultation
connection, and if the user goes on-hook during the Consultation
connection, the operation is treated as an AOCS misoperation. This
recovery of misoperation will take place even if the MPO package is not
equipped. In this case, the controlling party is re-rung by the held party
regardless of the CCDO and the recovery of misoperation options.
If an analog (500/2500 type) telephone user attempts to set up a
Consultation connection by dialing a busy DN and if the Call Waiting
conditions are satisfied, the controlling party will hear ringback tone and
the active party will hear Call Waiting tone. If the controlling party goes
on-hook before the active party has answered, the held call is disconnected
regardless of the MPO options and Call Waiting tone is removed from the
active party.
Night Restriction Classes of Service
If Call Waiting and Night Restriction for Call Waiting Class of Service
(NRWA) are assigned, Call Waiting is operational for the set only when
Night Service is in effect.
