AT&T 2400 manual

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 hol ding 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-answerrecall 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.
