Message Registration Description and operation

Description

Message Registration (MR) is an optional software package that meters local

calls over designated central office (CO) trunks. The Message Registration

(MR) feature counts Reverse Battery (RVB) pulses from outgoing loop start

or groundstart CO trunks. Pulses received are stored insoftware meters. Each

meter is assigned to a Directory Number (DN) or trunk access code that

requires metering.

The Message Registration feature allows each customer within the system to

keep an accurate record of CO calls for billing and administration purposes.

— Each Directory Number (DN) of three or more digits, including the

attendant DN, canbe assigned a software meter. For multiple appearance

DNs, only one meter is assigned to meter all calls to the Prime DN

(PDN). Stations with multiple DN keys have a meter allocated for each

DN key.

— Meters can also be assigned to tie trunk routes. A tie route meter can be

assigned to the route access code of each tie route in the customer group.

An access code for a metered route must be at least three digits long.

— The system automatically assigns one customer meter for each customer

within the system. Thiscustomer meter is used to store pulses that cannot

be added to particular DN or trunk meters assigned in the customer

group.

Software meters are assigned in LDs 10 and 11. Each meter number

corresponds to the DN or trunk access code to which it is assigned. Meters

can be either ON or OFF. When a meter is turned off, pulses received are not

stored. The customermeteris always on andcannot be turned off. Meters can

also be turned on or off individually or in groups, using a background

terminal (BGD).

553-2701-101 Standard 4.00 April 2000

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.

— Metercontents areaccessible fromdigital telephonesequippedwith 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 chargesand meterdata providedto the attendants appear onthe BGD and

are classified into five categories:

ROOM guest room DN (CCSA)

ADMN administrative phones (CCSD)

ATTN attendant consoles

TRK outgoing CO trunks

CUST customer DNs

Feature interactions

Multiple Appearance Directory Numbers

Multiple AppearanceDNs are chargedon the meterassigned to the Prime DN

(PDN). Data calls are charged to the originating telephone. Maintenance tests

on metered trunks do not affect the metered values.

Call Transfer

Only the party originating the Call Transfer is metered.

Call Forward

On calls where the Call Forward feature is used, the last party to forward the

call is metered. This applies to cases where a CO call originates from a Call

Forward station, and to cases where an established CO call is transferred to a

station that is forwarded to another internal station.

Conference

Only the party originating the Conference Call is metered.

Trunk-to-trunk calls

Metering of trunk-to-trunk calls using an outgoing CO trunk is not supported

if the trunk access code is a one- or two-digit access code. Otherwise, a meter

corresponding to the trunk access code of the metered trunk route is

incremented. Only three- and four-digit codes are supported forDNs or trunk

access codes.

Attendants

For attendant-originated calls to CO trunks, the attendant meter is

incremented. When the call is extended, the attendant is metered until a

telephone within the Meridian 1 is added to the conference. When the

attendant uses a loop key, the call is metered to the Room DN connected

through that key; otherwise, the attendant meter is incremented.

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

•QPC526

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.
