Operating parameters
The MR package must be supported by a BGD with Controlled Class of
Service Allowed (CCSA). The feature is not supported by attendant
administration.
MR is mutually exclusive with Coordinated Dialing Plans (CDPs), and
Centralized Attendant Services (CAS).
One- or two-digit DNs or access codes cannot be metered.
Feature administration
Each CO route must be declared as metered or nonmetered in LD16, trunk
route data block. Calls should not be allowed to overflow from metered to
nonmetered routes.
A software meter must be assigned in the Customer Numbering Plan to each
DN or trunk access code for which metering is desired.
Hardware description
MR is supported on Options 51C, 61C, and 81C.
Trunk circuit cards
One of the following trunk circuit cards must be used for trunks where
metering is required.
• NT5D29AA
• NT5K18Ax
• NT5K82
• NTCK16Ax
• NTCK18
• QPC525

The choice of card depends on two factors: whether the trunks involved are
loop or ground start, and whether system operation is A-law or
µ
-law.
