Installation Standards for
Meridian Mail Enhanced Card Option

The purpose of this document is to put forth standards for use by the technician installing Nortel Option 11 PBXs with Meridian Mail Enhanced Card Option voice mail systems. This document should serve as a guide to assist installers and database personal. It is not intended as a replacement for the installation manuals shipped with the systems. In cases of conflict with the published installation manual, the published manual takes precedent. It is the responsibility of the installer at site to read all provided Technical Service Bulletins and/or other documentations that Nortel provides to show updated installation information with each shipped system, in other words RTFM.

The enhanced card option Meridian Mail (hereafter referred to as MM) is comprised of a full sized printed circuit board (PCB) to which a hard drive, and up to two daughter boards, are attached. A tape drive unit, used for initial program load and database backup is connected to the PCB by a provided cable.

Refer to this Installation Guide to install MM software from tape.

The main PCB provides for four (4) ports of MM service. Each additional daughter board provides an additional four (4) ports of MM service. The normal configuration for the Janus program will include twelve (12) ports. This is the maximum number of ports that can be installed on a card option MM. Additional cards cannot be installed in the PBX expansion cabinets.

MM ports are of two types:

The amount of storage provided will be between ten (10) and twenty four (24) hours.

The number and type of ports and the amount of storage time is determined at the time of install by the KeyCode. All installers should verify the KeyCode matches the configuration shown on the site LOM at the time of the switch inventory. Do Not wait until it is time to install the MM software to verify that a valid KeyCode exists.

MM Port Configurations

MM ports are programmed in the Option 11 PBX database as M2008 sets. The default TNs for these ports should not be changed. The following table shows the relationship between the physical MM ports and the TNs assigned in the PBX database.

MM Port Port Location Option 11 TN
1 Main PCB 10 – 04
2 Main PCB 10 – 12
3 Main PCB 10 – 05
4 Main PCB 10 – 13
5 Top Daughter Board 10 – 00
6 Top Daughter Board 10 – 08
7 Top Daughter Board 10 – 01
8 Top Daughter Board 10 – 09
9 Bottom Daughter Board 10 – 02
10 Bottom Daughter Board 10 – 10
11 Bottom Daughter Board 10 – 03
12 Bottom Daughter Board 10 - 11

The correct programming of the M2008 sets in the PBX database is shown in the Enhanced Card Option Installation and Maintenance Guide, and at the bottom of this document. Note: the number zero (0) should be used for the CLID entry on key 0.

Card option Meridian Mails will be equipped with both basic and full service ports (depending on Keycode). Basic and full service ports should not be programmed in consecutive MM port order. The main PCB and each of the daughter boards should have a mix of both full and basic ports to provide for maximum redundancy.

At least two ACD groups need to be programmed for voice mail and auto-attendant functions on the Option 11. It is recommended that the following numbering plan be used on all sites except where it causes conflicts with existing or new DID DN assignments. Both ACD groups are programmed as MCDN’s according to Enhanced Card Option Installation and Maintenance Guide.

An example TN is shown here: ACD Programming

Full Service Ports - Voice Messaging: 5555
Full Service Ports - Express Messaging: 5590

Basic Service Ports - Auto Attendant: 5100
Basic Service Ports – Prompt Maintenance 5199

For simplicity’s sake the agent position id and SCN required for each M2008 should be numbered consecutively according to the physical MM port. The following table should make this clearer:

MM Port TN Type*  ACD Position ID SCN (key 1)
1 10 – 04 Full 5555 5001 5021
2 10 – 12 Full 5555 5002 5022
3 10 – 05 Basic 5100 5003 5023
4 10 – 13 Basic 5100 5004 5024
5 10 – 00 Full 5555 5005 5025
6 10 – 08 Basic 5100 5006 5026
7 10 – 01 Basic 5100 5007 5027
8 10 – 09 Basic 5100 5008 5028
9 10 – 02 Full 5555 5009 5029
10 10 – 10 Basic 5100 5010 5030
11 10 – 03 Basic 5100 5011 5031
12 10 - 11 Basic 5100 5012 5032

*The number of basic vs. full service ports will be determined by the KeyCode and will change from site to site.
Basic = Auto Attendant, Full = Voice Messaging

Security and Voice Messaging Defaults

Recommended Meridian Mail caller security prohibitions are; NO outcalling, and NO direct inward access to system or mailbox programming. To achieve the first prohibition is realitively easy, set the on-switch permission list to only allow calls to exiting extensions and the attendant while denying calls to trunk and BARS/NARS access codes. Then make sure anywhere in the database where a permission list is requested, ONLY the On-Switch list is used. To insure that no direct access to system or mailbox programming is not allowed, do not use a DID extension number for any of the messaging services listed above.

Voice Security Menu – Recommended defaults

Function MM Default Pref. Default Comments
Password Prefix 0 None Make sure the “0” is deleted
Maximum invalid logon attempts per session 3 3  
Maximum invalid logons attempts per mail box 9 9  
Maximum Number of Days permitted between Password Changes 90 0 Setting at “0” allows passwords to last for life of mailbox
Minimum password length 4 4     
External Logon     Enabled, Cannot Change

Class of Service Defaults

Generally three different class of services are built; Basic, Exec, and Admin. Meridian Mail has a default class of service named personal that a mailbox will be assigned to if no other COS is chosen. It is very important that this class of service not be used as it allows for off-site notification of messages and other features that may be a violation of customer standards.

*Note: The time allotted for greetings and message length are multiplied by the number of mailboxes in the system, and can significantly impact the time available for other services. On a more common sense issue, greetings should consist of the mailbox owners name, a brief statement explaining that the call is being answered by voicemail and a request for the caller to leave their name, phone number and a brief reason for the call. In no case should greetings be longer than 30 seconds, even if the mailbox user is giving the greeting in two languages. Anyone who requests a longer time should be using an announcement service.

**Note: The Meridian Mail will only play the name if the personal verification is recorded by the user.

Meridian Mail systems from Release 13 have some added options not available before. These are shown in the table below:

Service Basic COS Extended Storage Admin Comment
Unread Message Retention (Days) 35 35 35 Any message this old is not worth listening to!
Disable Message Reception ? ? ? See Note Below

Note: Release 13 gives the administrator the ability to disable a mailbox from recording messages if the mailbox storage is full, or if the user records a temporary access greeting. The user or administrator can also determine if the caller is transferred to a custom revert DN or an operator if a mailbox is not recording mailboxes. As these features are relatively new, a consensus on the implementation of them has not yet been formed and installers should their own best judgment, as dubious as it may be, when using these features.
