When you configure MESA-Net TCI?/IP, as described in the Procedures section of 
this chapter, you define the following parameters: 
The module number that contains the ethernet card to use for 
MESA-Net TCI?/II?, and the number of the ethernet card in that 
module. You can only configure MESA-Net TCI?/II? on one module of 
a multi-module Centigram server. 
The System Node Name, which is used by MESA-Net in reports. 
The System Local Node Number, which is used by MESA-Net to do 
message routing (see chapter 5 for information on configuring the 
Network Node Table). 
System Network Message Limit in number of minutes 
The number of Send and Receive Circuits (virtual circuits) to be used by 
MESA-Net. The number of circuits determines the throughput. You 
can configure a node with more of one type of circuit than the other, if 
needed.

et TCP/l 
As mentioned in Chapter 1, you cannot configure both MESA-Net Async and 
MESA-Net TCP/IP in the same module of a Centigram Series 6 server. However, 
you can configure a Model 640 server with MESA-Net Async in one module and 
MESA-Net TCP/IP in another, and the server can then communicate with remote 
nodes running either type of MESA-Net. 
Only one type of connection, Async or TCI?/IP, can exist between any two nodes.

							MESA-Net Async connects Centigram servers together by means of direct 
connection, modems, and multiplexers (or any combination of these). MESA-Net 
Async is flexible to support the varied requirements of different sites and networks. 
0 
For nodes with iow network traffic volume, a simple MESA-Net Async 
installation enables two links. The node can connect to all other MESA- 
Net Async nodes on the network (up to the network maximum of 
1500 
nodes), but only two at any given time. The MESA-Net Async optional 
feature diskette contains all of the files needed to run basic Mesa-Net 
Async. 
e 
The Multiple Links optional feature allows a node to simultaneously 
connect to as many as 16 nodes (32 for Model 640 servers). This feature 
is useful at centralized hub nodes. Different Link Enable optional 
feature diskettes (which used to be called the Link Lock diskettes) 
contains software to enable different numbers of links. 
The Parallel Links optional feature increases throughput by enabling 
multiple links between two nodes. The additional throughput can 
significantly speed up message delivery bemeen high-traffic nodes. You 
enable this feature with the Parallel Links optional feature diskette. 
Model 640 servers with more than one module can provide fault- 
2 tolerance and balanced traffic load for MESA-Net Async. By installing 
the appropriate hardware inzultiple modules, you can configure the 
Model 640 to support more links and balance the traffic load. In 
addition, one module can continue to process network traffic if the other 
modules are out of service. You must install a Link Enable diskette to 
support more than two links. 
You install each of these optional features on the Centigram server by following the 
standard procedure for installing VoiceMemo optional feature software. You then 
must configure the appropriate answer and originate links on the server.

To support MESA-Net Async, you must install one or more expansion serial cards in 
each Series 6 server on the network: 
Q For the Model 701, 1201, and l2OS, you can use either a 4-port 
Smartcard or a Serial 16/32 card. 
e For the Model 640, you must use the Serial 16/32 Card. If you are using 
MESA-Net Async Load Share on a Model 640, you can install Serial 
16/32 Cards in the two module that will have MESA-Net links. 
For complete reference information about the Smartcard, Serial 16/32 Card, and the 
KS232 cables, refer to 
the Centigram. Series G TechnicaL Reference ManuaL. That 
manual contains information about card and cable configuration, including jumper 
and switch settings, pin assignments, and common cable configurations. 
For step-by-step instructions on installing the Smartcard and the Serial 16/32 Card, 
refer to the procedures in this chapter. 
MESA-Net Async provides four hardware options for connecting Centigram servers 
together: direct connection, modems, multiplexers (discussed in Appendix B)? and 
digitaI line adapters (CSU/DSU). A MESA-Net network can support any 
combination of these hardware options. 
Direct Connection 
A direct connection is defined as two Centigram servers connected to one another via 
MESA-Net without using an intermediary communications device, such as a 
modem. 
You can use a direct connection to link servers that are collocated or geographically 
distant from one another. You can connect two collocated servers by using a 25pin 
null modem RS232 cable. You can connect two remote servers by means of modems 
over a leased analog line, or with a CSU/DSU on a leased digital line. Figure 3-l 
shows a MESA-Net Async direct connection.

A direct connection between co-located nodes 
is made by connecting a null modem cable 
between an Originate Link on each node and 
an Answer Link on the other node. 
There is a procedure at the end of this chapter that describes how to make a MESA- 
Net Async direct connection. 
Most MESA-Net Async connections are made using modems. Currently, Centigram 
has certified the following modems for use with MESA-Net: 
Telebit T25OO/World Blazer modem 
9 
AT&T Paradyne 3810/3820 Plus (V.34) 
8 
US Robotics Courier V.34/V.Everything - 
Each network serial port requires 
a modem, so you need at least two modems per 
Centigram server, one to answer messages and one to originate messages. Figure 3-2 
shows a MESA-Net Async modem connection.
