L7583A/B/C/D Line Card Access Switch

Table 9. Ring Return Switch, 7

* This parameter is not tested in production. Choice of secondary protector should ensure this rating is not exceeded.

† Applied voltage is 100 Vp-p square wave at 100 Hz.

Table 10. Ringing Access Switch, 8

* At the time of publication of this data sheet, the current device design will be a nominal 4 mA. Devices are being redesigned to reduce this

current to less than 2 mA nominally. Consult your Lucent Technologies Microelectronics Group account executive for additional details.

† Choice of secondary protector and series current-limit resistor should ensure these ratings are not exceeded.

‡ Applied voltage is 100 Vp-p square wave at 100 Hz.
