12.3 Metering Pulse Detection
Some Central Office switches (mostly outside of the USA) send 12- or 16-KHz metering pulses to indicate
to the system that a unit of connection time has been used. These pulses can be counted by the Phone Line
Manager 16 x 4 and appear as part of the Call History record output. If your unit is equipped with the
metering pulse-detection hardware, this command will enable the detection of the metering pulses.
To Enable metering:
1. In the programming mode, enter 7816. Pause for confirmation tone. Hang up or continue with
programming.
To Disable metering:
1. In the programming mode, enter 7817. Pause for confirmation tone. Hang up or continue with
programming.
12.4 Metering Pulse Frequency
If metering is enabled, you must select either 12- or 16-KHz as the frequency to be detected.
To select 16-KHz as the metering frequency:
1. In the programming mode, enter 7818. Pause for confirmation tone. Hang up or continue with
programming.
To select 12 KHz as the metering frequency:
1. In the programming mode, enter 7819. Pause for confirmation tone. Hang up or continue with
programming.
12.5 Caller ID
If your Phone Line Manager 16 x 4 is equipped with the optional Caller ID feature, this parameter should be
enabled to allow the Phone Line Manager 16 x 4 to capture the Caller ID data sent by the Central Office
switch between the first and second ring of an incoming call. This information will be output on the RS-
232C port of the system to a computer equipped with appropriate translation and display software. The RS-
232 port must be in the “Features Mode” to allow the information to be output normally or in the “System
Mode” to allow the information to be transmitted via the CAT interface, if your Phone Line Manager 16 x 4
is equipped with the CAT version of the software.
To enable Caller ID detection:
1. In the programming mode, enter 7828. Pause for confirmation tone. Hang up or continue with
programming.
To disable Caller ID detection:
1. In the programming mode, enter 7829. Pause for confirmation tone. Hang up or continue with
programming.
It is also possible to display the Caller ID information on the LCD screen of the Key Phones. The BK-416
EX series of key phones can display the incoming call number while the AVT-16 series of key phones can
display both name and number.
