Introduction and Requirements for Integration
In addition to the hardware and software listed in Table 1-3, you must provide the
following administration on the NEAX 2400.
■
Program the PA-16LCQ analog ports to provide an adequate loop current
disconnect, or
wink . The PA-16LCQ card provides a default value of
approximately 128ms wink. The wink can be increased to approximately
448ms with a firmware upgrade from NEC. Without the upgrade and the
increase, two items occur:
— Call holding times increase substantially because the default
disconnect time is lower than the minimum time required by the
INTUITY System.
— Call answer messages end with a reorder tone of approximately
one second.
■
Set the recall timer on the NEAX switch to an amount of time longer than
the ring-no-answer time. If you do not, calls blind transferred to
subscribers administered for
forward on ring-no-answer recall back to the
INTUITY System channel.
■
Administer the INTUITY System to transfer calls to a station other than an
actual attendant console, for example a digital telephone capable of
displaying calling party information. The NEAX 2400 switch does not allow
stations to transfer calls to an attendant console.
