General Description
This feature provides the Attendant with visual indications of either busy, idle or LINE LOCKOUT [L-3]
conditions for a particular hundred's group of stations via a designated lamp field on the Attendant
Console.
Operating Procedure
To operate:
1. Press an idle loop key.
2. Key in thousands (where applicable) and hundreds digit(s) of the desired group.
For example:
a.) To monitor the stations 200 to 299, dial “2”.
b.) To monitor the stations 2200 to 2299, dial “22”.
3. Lamp status indicates a busy (light steady), idle (no lamp), or LINE LOCKOUT [L-3] (lamp
flashing) condition.
For example: If ANPD and ASPA are blinking:
a.) ANPD 3 = NND 2
b.) ASPA 30 = STN
To monitor STN 3000 to STN 3099, key in 300.
Service Conditions
1. For 3-digit station numbers, the digital display will show the first digit of the group being
monitored (100's, 200's, etc.). Lamps 00-99 will provide visual indication of the status of each
station in the selected group.
2. For 4-digit station numbers, the digital display will show the first two digits of the group being
monitored (1100's, 1200's, etc.). Lamps 00-99 will provide visual indication of the status of each
station in the selected group.
3. The Busy Lamp Field (BLF) display is applicable for 3, 4, and 5-digit station numbering plans.
4. Operation of the BLF supersedes the display of the CALL WAITING LAMP [C-13] feature.
5. The lamp indication for LINE LOCKOUT [L-3] is an LED flashing at 60 pulses per minute.
6. LINE LOCKOUT [L-3] lamp indication can be provided by system data base programming.
7. This service feature is not available with the NEAX2400 ICS system.
8. The BLF does not indicate busy/idle status for stations located in CCIS satellite offices.
Interactions
1. CENTRALIZED ATTENDANT SERVICE (CAS) [C-20]: At the CAS main location, when the
ATTENDANT CONSOLE [A-3] is handling a call from a CAS branch over a Release Line Trunk
(RLT), the BLF will give no indication of busy/idle status of branch location stations.
2. The BLF indicates the station status after the hundreds digit is keyed in by the Attendant.
3. A 2-digit digital display indicator is used to display the thousands and hundreds digit of the
displayed stations.
