La Jacks (Dedicated Lines And Power Failures); Optional Equipment - Lucent Technologies SPIRIT 2448 Administration Manual

If your system requires a PBX/Centrex line access code, you should customize that code through
the system customization process (see page 17). If the line access code is customized, the
system will automatically enter a pause to wait for a dial tone after the code is dialed as part of
a SpeedCall number. If the code is not customized, the system may consider the code part of
the telephone number and not be able to check the digits for toll call restrictions.
A SPIRIT system behind a PBX or Centrex may not act as expected in some cases. For
example, If you were previously using such a system, you could distinguish between "inside"
and "outside" calls by the ringing pattern. Now if you are using a SPIRIT system behind
PBX/Centrex, "inside" calls include only SPIRIT Intercom calls, and all other calls will ring as
"outside" calls.
If you are using both SPIRIT and PBX/Centrex features, be sure you remember to access
each feature as required. To access SPIRIT features, you must be using INTERCOM; to access
PBX/Centrex features you must be using a PBX/Centrex line. You may have some unexpected
and confusing results if you attempt to access a PBX feature on INTERCOM, or a SPIRIT
feature on a PBX/Centrex line.
If there are some PBX/Centrex features that you use often, you can program them as personal
SpeedCall numbers for easy access. First, make sure you have the code for the PBX/Centrex
feature you wish to access. Then, following the procedure outlined in the User Manual, program
the following as a SpeedCall number: RECALL, PAUSE, Feature Code. You can then use SpeedCall
to access the PBX/Centrex feature.

LA Jacks (Dedicated Lines and Power Failures)

Dedicated Lines
One jack for each four line jacks is labeled LA on the controller. LA means Line Auxiliary.
These jacks provide standard telephone service unaffected by system features and are useful as
dedicated lines for computer modems, answer/record machines, and in power failure situations.
The controller and expansion unit have a "line card" for every four incoming lines in the
system. There is one LA jack for every line card installed in your controller or expansion unit.
Each LA jack uses the same incoming line as the lowest numbered line on the card. When
the LA jack on a line card is being used (that is, the device plugged into that jack is "offhook" and
is actually being used), the lowest numbered line on that line card will be unavailable for use
by the system. Devices may be left plugged in the LA jacks, and as long as they are not in
use they will not interfere with the lines.
Power Failures
The LA jacks may be used with a standard telephone during a power failure when the rest of
the system cannot be used. Simply plug one end of a telephone line cord into one of the
LA jacks and the other end into a standard telephone.
During power failures less than 2½ days, the customization memory will be maintained;
however, the system clock will not continue to run during the power outage. If you are using
Call Reporting you should reset the time and possibly the day depending upon the length of
the power failure. During power failures of more than 2½ days, the memory will be lost and all
customized features will reset to the installed setting. Be sure to keep a record of current
customization.

Optional Equipment

The controller has jacks for a music on hold source, and an external alerter. A volume control
for the music on hold is located next to the music on hold jack on the controller. The controller
also has an SMDR (Station Message Detail Recording) jack for a serial printer or personal
computer. Several models of serial printers and personal computers are available for use with
the system, but a 355A or 355AF RS232 adapter MUST be used with ANY of this equipment.
There are also loudspeaker paging systems available for use with the SPIRIT system. See your
AT&T representative for more information.
