Each software meter can store up to 32,766 pulse counts before automatically
resetting to 0. When a meter is reset, a message is printed on the system
maintenance terminal, the BGD, or both, indicating that a reset occurred.
Overflow messages display information on meter contents for any DN or
trunk access code requested:
— Station or trunk TN
— Station DN or the trunk-access code
— Trunk TN (outgoing CO trunk used for the call)
— Customer number for their station or trunk
— Meter count before reset (32766)
The message for a customer meter overflow appears as follows:
CUST MTR xx OVF 32766
When equipped with the MR feature, the system is capable of the following
provisions:
— Attendants are able to meter outgoing local calls over CO routes.
— Meter contents are accessible from digital telephones equipped with digit
display and a Message Registration key/lamp pair.
— Meter contents are also accessible from BGDs.
The system uses class of service (COS) to distinguish between room phones
and administrative phones. Room phones have Controlled COS Allowed
(CCSA), while administrative phones have Controlled COS Denied (CCSD).
Call charges and meter data provided to the attendants appear on the BGD and
are classified into five categories:
ROOM
ADMN
ATTN
TRK
