Operation
Metering is applied on a route basis. When setting up a customer for the
feature, CO routes that are to be metered should only have access to routes
that are metered. Calls should not be allowed to overflow to a nonmetered
route. The BGD and the Meridian digital telephones can show the
accumulated number of calls for each DN meter assigned.

The following four MR options can be set from a BGD:
For a complete and detailed description of all the BGD commands, refer to
the Background Terminal Facility description (553-2311-316).
The general command format for the BGD appears as follows:
SEt OPtion <opt> ON
SEt OPtion <opt> OFF
<opt> = any combination of AL1, X, RA, and CO
All of the commands for the BGD/MR can be turned on or off with the
following commands:
SEt OPtion ON
SEt OPtion OFF
AL1 Value set for all Room DNs in the customer data block
X Represents all possible values for a digit in a DN, so that
