Storing Charging Information; Reading And Changing Meters - Nortel Meridian Meridian 1 Feature Description And Administration

Storing charging information

Charging information is stored using meters, which may be assigned to sets,
attendant consoles, trunk routes, and customers as follows:
• one meter is assigned to each set, via Metered Assigned (MRA) Class of
Service, on a TN basis. The charge unit count is stored in the meter of the
station TN from which the call is made;
• one meter, classified as "ATTN", is provided to collect charges for all
metered calls made by attendant consoles within the same customer;
• one meter, classified as "ROUTE", is provided for each route;
• at each node, one meter classified as "CUST" is provided for each
customer to accumulate any charges that cannot be charged to any other
meter for the customer.
• one temporary meter, classified as TRK, is provided for each trunk; this
temporary meter is used to accumulate charges for each call. At the end
of the call, the charge is added to the permanent meter associated with the
caller.
Note: The same station meters are used to store charging units for PPM
and AOC. To handle a possible difference in unit costs between PPM and
AOC, charge units received for an AOC metered call may be converted
into internal charge units using a "Route Unit Conversion Factor"
(RUCF) configured in Overlay 16.
The charging information may also be recorded in the Call Detail Recording
(CDR) record, as provided by the CDR Enhancement capability (for more
information on the CDR Enhancement, refer to Features and Services
(553-3001-306)). This information is printed at the end of call, and appears in
the same location of the CDR ticket as the PPM call charge information
would appear, immediately following the PPM counts.

Reading and changing meters

Meters of Multiple Appearance DNs (MADNs) can be changed using the
SET METER DN or SET METER TN command at a Background Terminal
TTY, or using the MTR key on a Meridian 1 telephone. To change only one
of the meters in a MAPDN group, only the Background Terminal TTY can
be used. For Automatic Call Distribution (ACD) stations, the meters can only
be changed using the POSN-ID prompt at the TTY.
