							When a user addresses a message, the VoiceMemo software must be able to identify 
the address as either a local mailbox or a remote mailbox. If it is a remote mailbox, 
the VoiceMemo software must be able to identify the correct remote node and the 
correct mailbox on that node. 
The Dialing Plan identifies the message address as either a local mailbox or a remote 
mailbox. The Digits Translation Table determines the correct node of the remote 
mailbox and how to derive the mailbox number from the address entered. Figure 
6-l shows how these two filters work together.

							Configuring the Dialing Plan 
You MESA-Net network will be much easier to maintain and expand if you carefully 
plan you network addressing in advance. You must consider any existing switch 
extension numbering and VoiceMemo dialing plans, and then create dialing plans on 
all nodes that allow easy access to all other nodes. 
Use the Planning Network Addressing Worksheet to gather the information that you 
need to create a network addressing scheme that meets your present and future 
needs. Study the sample worksheet and descriptions below, and then copy the blank 
worksheet at the end of this chapter and fill in the information for your network. Be 
sure to include an entry for your local node.

Node Number: The number of the node for this entry. Each MESA-Net node on 
the network must be represented by a unique number. You can use numbers from 
1 
to 8 191, but the maximum number of nodes is 1500. 
Node Name: The name or location of the node.

							Configuring the Dialing Plan 
Mailboxes Start with: Circle the numbers that are used at the node as the first digit 
in user mailboxes. For example, if mailboxes at a node are in the 3000 and 4000 
range, circle 3 and 4. 
Length of Mailbox Numbers: For each number that you circled, write in the 
number of digits in mailboxes that start with that number. If mailboxes have 
variable lengths, write V. 
The Digits Translation Table is the “sorting machine” or “routing table” for network 
messages. When a user addresses a message to a remote mailbox, MESA-Net 
compares the mailbox address to the prefures listed in the Digits Translation Table. 
The Digits Translation Table tells where the message is going, and how many digits 
the remote node must delete (“absorb”) to find the destination mailbox. 
The following excerpt from a Digits Translation Table indicates that any mailbox 
addresses that begin with 21 or 22 are to be routed to node 2 (Chicago), and any 
addresses that begin with 23 are to be routed to node 8 (Dallas). In addition, the 
remote nodes must strip off rcyo digits (the prefer) to find the destination mailbox 
number.

Centigram recommends that the table be the same in each node. You can enter your 
local npde number in this table. If some nodes are not allowed to communicate with 
certain remote nodes, then use the GC%&S feature to properly segregate those 
communities of interest. 
(See the VoiceMemo Reference and Conjguration Manual 
for more information on GCOS.) 
e Prefixes 
All network messages are routed by the node prefxes in the Digits Translation Table. 
Node pref=es are the leading digits of network mailbox numbers that are unique to a 
node. In the sample Digits Translation Table above, the pref= 23 uniquely 
identifies node 8; only network addresses at node 8 begin with the digits 23 
The length of an individual pref= depends on whether you are using access codes 
(see below) and whether mailboxes on two or more nodes share the first, second, 
third, fourth, etc. digits. Each prefer consists of a number of shared leading digits, 
plus one digit that is found only in the mailboxes of a single node. 
6-3  
						

							Configuring the Dialing Plan 
Example: 
The San Jose node has the following dialing plan: 
4,Nh,N4,N4,4,4,4,4,4 
This means that the remote mailbox numbers that San Jose can access begin with 2, 
3, or 4, and consist of four digits. 
The Chicago node (Node 2) uses mailbox numbers 2000 to 2999, and 3000 to 3250 
The New York node (Node 4) uses mailbox numbers 3260 to 3999, and 4000 to 
4499 
The Dallas node (Node 6) uses mailboxes 4500 to 4999

							Configuring the Dialing Plan 
Because none of the nodes have overlapping mailbox numbers, the digits to absorb 
count is 0 for all prefures. The San Jose Digits Translation Table would look like 
this:

If a message is made for remote mailbox 3267, MESA-Net checks the table, sees that 
prefer 326 matches this mailbox, adds a flag to the message that tells the remote node 
to absorb no leading digits from the incoming mailbox number, then adds the 
message to the queue for node 4. 
Note the variation in the number of digits needed to make a prefer unique to a node. 
Chicago is the only node using mailboxes that begin with 2, so that prefz only needs 
to be one digit. Chicago and New York both uses mailboxes in the 3200 series, so 
these prefures must be taken out to the third digit to be unique. 
Another thing that is noteworthy about this dialing plan is that no remote mailbox 
numbers overlap, either with each other or with local San Jose mailboxes. New 
York, Chicago, and Dallas could use mailbox numbers that begin with 1, 5, 6, 7, 8,

and 9, but users on the San Jose system cannot send messages to these mailboxes 
through MESA-Net. The digits to absorb feature can be used to add flexibility to 
the dialing plan. 
igits To Absorb 
You assign a Digits To Absorb number to each prefer in the Digits Translation 
Table. The number of digits can be from 0 to 10. After MESA-Net matches the 
destination mailbox number to a prefer, it attaches the corresponding Digits To 
Absorb count to the message. The remote node deletes the specified number of 
leading digits to convert the network mailbox number to a local mailbox number. 
You must configure each node to send Digits To Absorb counts that allow remote 
nodes to translate network mailbox numbers to valid local mailbox numbers. 
Digits to Absorb and local Mailboxes 
If local mailbox numbers match a dialing plan position that contains an N, then 
there must be a prefix entry in the Digits Translation Table that has the local node 
number. 
If every node on the network uses the same dialing plan, all mailboxes must be the 
same length. For example, if every node on a network uses the dialing plan 
NZNZNZNZNZNZN7,NZNZ users on every node are permitted to make 
messages for local or remote mailboxes that have 7 digit numbers only. Since 
MESA-Net does not absorb digits from local mailboxes, all local mailboxes on every 
system must be 7 digits; therefore, no digit absorption is possible throughout the 
network. The following section shows a way to formulate a network-wide‘ dialing 
plan to avoid this limitation. 
Using the Digits to Absorb Feature to Create “Access Codes’” 
Thejdigits to absorb feature can simp&fjl Digit Translation Table configuration by 
allowing each node administrator to formulate “access codes” for the other nodes on 
the system. A user enters the access code for the node before entering the mailbox 
number of the recipient when making a message for a remote mailbox. For example, 
if the access code for Boston is 82 and the mailbox you want to reach is 100, you 
would enter 82 100. 
You can implement this feature with the either N or the I? character in the dialing 
plan. With the N implementation, users will enter just the access code and mailbox. 
With the I? implementation, users will enter a “nenvork” access code digit, 
identifying that a network message is being made, then a “node” access code, 
identifying the destination node, then the destination mailbox number. 
The access codes are prefures in the Digits Translation Table; the associated digits to 
absorb count tells the remote node to delete the access code to obtain the local 
mailbox number. Problems with mailbox number overlap between remote nodes are

avoided, since’the “real” mailbox number (the local mailbox number on the remote 
node) is obtained after the message is sent. 
bsorb Feature to Create Same- 
If you want users to always enter the same number of digits for all network addresses, 
you can use the Node Prefures and the Digits to Absorb feature in the Digits 
Translation Table to “pad out” the mailbox numbers for nodes that use shorter 
extensions. For example, if node 2 uses 3-digit extensions and node 6 uses 4-digit 
extensions, you can create prefures for node 2 that are one digit longer than the 
prefures for node 6. You also set the Digits to Absorb count for node 2 to be one 
digit greater than the Digits to Absorb for node 6. The sample Digits Translation 
Table below shows this kind of configuration.

When you initially configure MESA-Net software on your Centigram server, you 
must set the dialing plans so that users can send network messages. You must set the 
dialing plan of every line group (VoiceMemo, Receptionist II, and so on) from 
which users will be allowed to send network messages. If any line group has more 
than one application, such as Receptionist II and an integration, remember to change 
all of the dialing plans. Do not change PBX dialing plans for Enhanced SMDI line 
groups. 
If the dialing plan for a particular application is not changed, a user who calls in on 
the lind group dedicated to that application will be unable to make messages for 
remote mailboxes. For example, Messa@ Delivery uses the dialing plan specified for 
the Pager Application. When Message Delivery calls a user at a pre-programmed 
telephone number because there is an unplayed message in the mailbox, the user 
enters the mailbox passcode and is logged into the mailbox. 
If the Pager Application dialing plan is -not changed to match the Network Dialing 
Plan, the user will be unable to make messages to remote mailboxes. To 
communicate with remote mailboxes, the user must call the standard VoiceMemo 
number, where he or she will log in under the VoiceMemo application 
When you configure the dialing plans for MESA-Net messaging, you must choose to 
use a network prefer digit, direct network addressing digits, or a star-prefix dialing 
plan.
