About the MicroRouter 1220i
Congratulations on your purchase of the MicroRouter 1220i multiport
wide area router. The MicroRouter 1220i supports the IP and IPX
network protocols, with leased-line and/or dial-on-demand operation
using the PPP, Frame Relay and/or SMDS wide area protocols.
A Note About Firewalls
The MicroRouter 1220i can be configured to be a very effective packet
screening firewall. However, you must carefully set up your network
and add packet filters in order for it to be effective in this role.
THE SHIPPING CONFIGURATION IN YOUR MICROROUTER
1220i DOES NOT PROVIDE AUTOMATIC FIREWALL PROTECTION. YOU MUST FIRST PROGRAM YOUR ROUTER TO WORK
IN THIS ROLE ON YOUR NETWORK.
v
Note: Due to the nature of the IP protocol, IP packet filtering can
be quite complicated. If you are attempting to design and implement a
comprehensive set of filters, or an Internet Firewall, there are a number
of references you should consult. Two good starting points are:

A Note About On-Demand Internetworking
The MicroRouter 1220i can be configured to provide cost effective
on-demand connections over a wide area communications link (typically a voice phone line, a switched 56 line, or an ISDN line). Your
network traffic and the configuration you place in the router will determine how often and for how long such a link is connected.

1220i DOES NOT PROVIDE AUTOMATIC ON-DEMAND INTERNETWORKING. YOU MUST FIRST PROGRAM YOUR ROUTER

MicroRouter 1220i Installation Overview
This manual will help you install the MicroRouter 1220i to connect two
local Ethernets to 1 or 2 remote networks and/or remote PPP client
computers. These connections can be made to other Compatible
Systems routers, routers from other vendors, or PPP compliant dial-in
software packages running on a variety of computers. The w ide-area
interfaces on the MicroRouter 1220i may be used to interconnect your
network with other corporate networks, and to make your network’s
resources available to dial-in clients.
In short, the installation steps are:
1.Install the MicroRouter hardware and connect it to one or more
line communication devices (including modems, 56K CSU/DSUs,
ISDN Terminal Adapters, and fractional or full T1 CSU/DSUs).
2.Select the management method you wish to use with the router. If
you want to use the CompatiView management software, you must
install the software on a Windows PC which is connected to your
network.
3.Configure the MicroRouter LAN and WAN parameters using the
management method you have chosen.
4.Connect the secondary WAN port’s RS-232 to an external line
communication device (including modems, 56K CSU/DSUs, and
ISDN Terminal Adapters).
The manual is divided into several sections that should provide you
with all the information you will need to use the MicroRouter 1220i on
your network. For the latest documentationon Compatible Systems

Needed For Installation
Before connecting the MicroRouter 1220i to your network, you need to
make sure that you have the necessary equipment for connecting to the
local Ethernets and the wide area transmission device(s) (modem, 56K
CSU/DSU, ISDN terminal adapter, T1 CSU/DSU).
Ethernet Connection Requirements
The MicroRouter 1220i’s Ethernet interfaces directly support 10BaseT
twisted-pair Ethernet. Other Ethernet cabling types (such as thin
Ethernet, thick Ethernet, fiber optic cabling or pre-10BaseT
twisted-pair) can be supported using a 10BaseT mini-hub or other
conversion device.
Chapter 2 - GettingStarted7
10Base-T Twisted-Pair Ethernet
To connect the router's Ethernet interface to twisted-pair Ethernet
cabling you will need an unshielded twisted-pair station cable that is
connected to a 10BaseT-compatible twisted-pair hub.
v
Note: Ethernet cables and cable connectors are not supplied with
the MicroRouter product. Please contact your reseller or your
Compatible Systems representative for information on obtaining the
correct Ethernet cabling supplies.
Telco Line Connection Requirements
In order to connect to non-T1 wide area transmission lines, you must
connect the router’s secondary wide area port to a modem, 56K
CSU/DSU, or ISDN Terminal Adapter. Which of these devices you use
depends on the type of telco line.
v
Note: Before attempting to connect the MicroRouter 1220i to a
leased telco line, use the loopback features of your CSU/DSU to check
the line. This can save you a considerable amount of time, since the
more equipment you have on the line, the more difficult it becomes to
determine where a problem is occurring.
The MicroRouter 1220i provides one high-speed V.35 synchronous
interface, and one RS-232 sync/async interface, each of which can be
independently configured for PPP, Frame Relay or SMDS operation.
The V.35 interface is capable of communicating to another router or a
PPP client machine over a 56K CSU/DSU, an ISDN Terminal Adapter,
or a T1 CSU/DS U. The RS-232 interface is capable of communicating
to another router or a PPP client machine over a modem, 56K
CSU/DSU, or ISDN Terminal Adapter.
V.35 Interface
The MicroRouter 1220i does not include a V.35 cable. These cables are
available from your reseller, or a number of other suppliers. The
MicroRouter 1220i has a female V.35 connector, as do virtually all line
communications devices. Thus, the V.35 cable required to connect to a
line communications device will usually have male connectors at both
ends. The pinouts for this cable are shown in Appendix B.
8Chapter 2 - GettingStarted
RS-232 Interface
The MicroRouter 1220i includes one DB-25 to DB-25 RS-232
sync/async cable. This cable supports RS-232 asynchronous modems,
synchronous leased and switched 56K CSU/DSUs, and ISDN Terminal
Adapters. It can also be used to connect the router’s auxiliary interface
to a PC running terminal emulation software, or to a dumb terminal.
v
Note: Please use only the supplied DB-25 cable when connecting
your line communication device to the MicroRouter 1220i’s RS-232
interface. The cables provided with other equipment may not have all
of the same internal connections.
