Make Busy versions of Modular Nest 9 and Modular Nest 21 backplanes (which
install in a Modular Nest enclosure with card modems) come equipped with the
Busy Out feature. This feature causes a Busy Out modem to “appear busy” to the
central office when:
• Power is disconnected from the Modular Nest enclosure
• The modem card is not present in its slot
• Busy Out=ON (the option is set through the front panel menu, the AT ACU, or
a network manager)
Busy Out is intended for use with Model 3262 and 3267 dial modems. In some
countries, it is also used in dial-restoral mode on Model 3263 and 3268 leased
modems.
