FEDERAL COMMUNICATIONS COMMISSION  
RADIO FREQUENCY INTERFERENCE STATEMENT:  
This equipment has been tested and found to comply with the  
limits for a Class A digital device, pursuant to Part 15 of the FCC  
Rules. These limits are designed to provide reasonable protection  
against harmful interference when the equipment is operated in a  
commercial environment. This equipment generates, uses, and  
can radiate radio frequency energy and, if not installed and used  
in accordance with the instruction manual, may cause harmful in-  
terference to radio frequencies. Operation of this equipment in a  
residential area is likely to cause harmful interference in which  
case the user will be required to correct the interference at his own  
expense.  
Shielded cables must be used with this unit to ensure compliance  
with Class A FCC limits.  
Change or modifications to this unit not expressly  
approved by the party responsible for compliance  
could void the user's authority to operate the equip-  
ment.  
CANADIAN EMISSIONS REQUIREMENTS  
This digital apparatus does not exceed the Class A limits for radio  
noise emissions from digital apparatus as set out in the interfer-  
ence-causing equipment standard entitled "Digital Apparatus,"  
ICES-003 of the Department of Communications.  
Cet appareil nuerique respecte les limites de bruits radioelec-  
triques applicables aux appareils numeriques de Class A pre-  
scrites dans la norme sur le materiel brouilleur: "Appareils  
Numeriques," NMB-003 edictee par le ministre des Communica-  
tions.  
 
CANADIAN EQUIPMENT LIMITATIONS  
Notice: The Canadian Industry and Science Canada label identi-  
fies certified equipment. This certification means that the equip-  
ment meets certain telecommunications network protective,  
operational, and safety requirements. The Department does not  
guarantee the equipment will operate to the user's satisfaction.  
Before installing this equipment, users should ensure that it is per-  
missible to be connected to the facilities of the local telecommuni-  
cations company. The equipment must also be installed using an  
acceptable method of connection. In some cases, the company's  
inside wiring associated with a single line individual service may  
be extended by means of a certified connector assembly (tele-  
phone extension cord). The customer should be aware that com-  
pliance with the above conditions may not prevent degradation of  
service in some situations.  
Repairs to certified equipment should be made by an authorized  
Canadian maintenance facility designated by the supplier. Any  
repairs or alterations made by the user to this equipment, or  
equipment malfunctions, may give the telecommunications com-  
pany cause to request the user to disconnect the equipment.  
Users should ensure for their own protection that the electrical  
ground connections of the power utility, telephone lines and in-  
ternal metallic water pipe system, if present, are connected to-  
gether. This precaution may be particularly important in rural  
areas.  
Users should not attempt to make such connections them-  
selves, but should contact the appropriate electric inspection  
authority, or an electrician, as appropriate.  
The Load Number (LN) assigned to each terminal device denotes  
the percentage of the total load to be connected to a telephone  
loop which is used by the device, to prevent overloading. The ter-  
mination on a loop may consist of any combination of devices  
subject only to the requirement that the total of the Load Numbers  
of all devices does not exceed 100.

Introduction  
Chapter 1  
PRODUCT OVERVIEW  
The ADTRAN Router Option Module installs in the option slot of  
the TSU muliplexer family of products and provides integrated rout-  
ing capability access frame relay or point-to-point networks.  
Basic Functions of Router Option Module  
The Router Option Module provides the following basic functions:  
LAN Bridge  
Bridging provides a point-to-point connection between two local  
area networks (LANs). The bridge learning function scans the  
source and destination media access control (MAC) addresses of all  
packets on its LAN and determines which packets should be trans-  
mitted over the T1 link. Applications include connectivity between  
single users or small offices to corporate LANs. The Router Option  
Module uses the Spanning Tree Algorithm (IEEE 802.1d-ISO/  
IEC10038), which provides a loop-free topology and redundancy.  
IP Router  
The Router Option Module can function as an IP router using the  
Routing Information Protocol (RIP) for advertising and learning  
routes among other routers. Static routes may also be entered into  
the routing table.  
IPX Router  
IPX routers and services can be exchanged between the Router Op-  
tion Module and other devices using RIP and Service Advertising  
Protocol (SAP). Watch dog serialization filtering and spoofing can  
permit the ISDN to be idle during no application traffic periods.

Chapter 1: Introduction  
Network Address Translation (NAT)  
Single networks can connect to the Internet with this function. The  
Router Option Module translates outgoing IP packets over the T1 to  
the IP router at the Internet Service Provider. Popular Internet ap-  
plications are supported.  
PPP or Frame Relay  
The layer 2 protocol used to transfer packets can be PPP or Frame  
Relay (RFC 1490). PPP allows a point-to-point connection, whereas  
Frame Relay can provide up to ten permanent virtual circuits.  
Routing and Bridging with the Router  
Option Module  
The Router Option Module is a Router and Transparent Learning  
Bridge. Its features can be easily configured and used, once several  
basic concepts are understood.  
Factory Default  
The Router Option Module comes from the factory configured for  
MAC Bridging, IP routing, and IPX routing with no filters or con-  
nection information defined. An IP address of 10.0.0.1 with a net-  
work mask of 255.255.255.0 is preloaded. The factory default layer 2  
configuration is PPP, which provides the least amount of reconfigu-  
ration due to its negotiation-oriented nature.  
Bridging  
In Bridge Mode, the Router Option Module can be used to connect  
two LAN segments. In this mode, all protocols are supported be-  
cause they are transported across the T1 link at the MAC layer. The  
Spanning Tree Algorithm can be used to guarantee a loop-free to-  
pology. MAC- save addresses are “learned” by each Router Option  
Module to prevent non-WAN packets from being bridged.  
IP Routing  
The Router Option Module operates as an IP router when the Con-  
figuration/IP/IP Router/Mode option is configured to On. In PPP  
mode, the Router Option Module uses an IP unnumbered WAN in-

Chapter 1: Introduction  
terface. The IP address and mask assigned to the unit’s LAN inter-  
face apply to all routing and IP operations for the unit.  
In Frame Relay mode, each PVC can be specified as numbered or  
unnumbered links. If a default gateway is specified on the network  
of the Ethernet interface, the unit attempts to reach the gateway  
through that interface. If no default gateway is specified (i.e.,  
0.0.0.0.), the WAN interface becomes the default gateway (recom-  
mended for remote applications when there are no other routers on  
the remote LAN).  
IPX Routing  
Network routes and services are learned and advertised using No-  
vell’s RIP and SAP.  
Concurrent Routing and Bridging  
The Router Option Module can route IP and IPX as well as bridge  
nonIP/IPX packets simultaneously. The PPP profile will, by default,  
negotiate PPP network protocols to support the transmission and  
reception of IP, IPX, and Bridge packets. If the PPP peer does not ac-  
cept a protocol, the Router Option Module will fall back to any com-  
bination of routing and bridging.  
Network Address Translation Mode (NAT)  
NAT is a special mode of operation in which the Router Option  
Module obtains a dynamically assigned IP address from the peer  
router (typically an Internet Service Provider). This allows a net-  
work of computers to appear as a single IP address.  
NAT is enabled if the layer 2 protocol is PPP and the PPP profile has  
the IP parameter NAT set to Yes, or the layer 2 protocol is Frame Re-  
lay and a DLCI mapping has the IP MAP/NAT parameter set to  
Yes.  
The network computer’s IP stack may use DHCP to request an IP  
address, default gateway address, and domain name server ad-  
dresses from the Router Option Module.

NAT/DHCP Mode  
Write security: 3; Read security: 5  
When this option is set to On, the Router Option Module acts as a  
DHCP server and will dynamically assign IP, network mask, de-  
fault gateway, and DNS addresses to any device which transmits a  
broadcast DHCP request. The addresses assigned are based on the  
Router Option Module’s own IP address and will be within the  
same network. This mode is most commonly used with the NAT  
functionality. The default is Off.  
NAT/DHCP Renewal Time  
Write security: 3; Read security: 5  
This is the number of hours that the DHCP server should allow the  
device before it is required to send a new DHCP request. The default  
is 15 hours. Zero (0) represents an infinite lease.  
NAT/Web Server  
Write security: 3; Read security: 5  
This is the IP address of a web server on the Ethernet network.  
When an active NAT connection is made to the Internet, any HTTP,  
FTP, or SMTP server requests from the WAN are translated and sent  
to this web server.  
Normally, communications across NAT must be initiated from the  
LAN side of the Router Option Module. Web server allows a single  
machine on the NAT side to be accessed from the Internet side of  
NAT. This provides outside access to a Web server, mail, or FTP  
server.  
NAT/Default IP  
This is the IP address used by the Router Option Module for Net-  
work Address translation when nothing is assigned during the PPP  
negotiation when PPP mode is active or when nothing is specified  
in the DLCI Mapping Link IP Address.

back-up in case the primary address does not respond to the re-  
quest.  
IP/UDP Relay  
The Router Option Module can be configured as a relay agent for  
UDP broadcast packets. Normally, a router will not forward UDP  
broadcast packets. However, many network applications use UDP  
broadcasts to configure addresses, host names, and other informa-  
tion. If hosts using these protocols are not on the same network seg-  
ment as the servers providing the information, the client programs  
will not receive a response without enabling the UDP relay agent.  
UDP Relay/Mode  
Write security: 3; Read security: 5  
When this option is set to On (def), the Router Option Module will  
act as a relay agent.

IP/Proxy ARP  
Write security: 4; Read security: 5  
This feature allows the network portion of a group of addresses to  
be shared between several physical network segments. The ARP  
protocol itself provides a way for devices to create a mapping be-  
tween physical (i.e., Ethernet) addresses and logical IP addresses.  
Proxy ARP makes use of this mapping feature by instructing a rout-  
er to answer ARP requests as a “proxy” for the IP addresses behind  
one of its ports. The device which sent the ARP request will then  
correctly assume that it can reach the requested IP address by send-  
ing packets to the physical address that was returned to it. This tech-  
nique effectively hides the fact that a network has been (further)  
subnetted.

Chapter 4: Configuration Overview  
If this option is set to Yes (def), when an ARP request is received on  
the Ethernet port, the address is looked up in the IP routing table. If  
the forwarding port is not on the Ethernet port and the route is not  
the default route, the Router Option Module will answer the request  
with its own hardware address.  
If set to No, the Router Option Module will only respond to ARP re-  
quests received for its own IP address.

The seed status defines what the Router Option Module is to do  
with the network information on the selected frame type during  
startup. There are three possible seeding selections specified:  
Seeding Selection Description  
Seed  
The Router Option Module will listen for  
an IPX network number being sent by  
another router (including Novell software  
routers residing on servers) on the Ethernet  
segment connected to this port and use this  
number if it exists. If it doesn’t discover a  
number in use, the Router Option Module  
will use the configured IPX network num-  
ber for the Ethernet segment.  
Non-Seed (def)  
The Router Option Module will listen for  
an IPX network number being sent by  
another router (including Novell software  
routers residing on servers) on the Ether-  
net segment connected to this port and use  
this number if it exists. If it doesn’t dis-  
cover a number in use, the Router Option

Configuration/Bridge  
The Bridge menu is used to set up the bridge parameters for the  
Router Option Module. The bridging function runs at the Media Ac-  
cess Control (MAC) level which allows any protocol packets that  
run over Ethernet to be forwarded. Bridging can run concurrently  
with the IP and IPX routing. However, when packets are bridged  
across a WAN connection, the following rules apply:  
• When IP routing is active, IP packets (which include ARP pack-  
ets) are not bridged.  
• When IPX routing is active, IPX packets are not bridged.  
• The WAN IP Bridge and WAN IPX Bridge menus allow the  
WAN connection to bridge packets to the Router Option Module  
but get routed as soon as they arrive at the unit.

Chapter 4: Configuration Overview  
Bridge/WAN IP Bridge  
When IP routing is active, the Router Option Module will allow an-  
other WAN device to bridge IP packets to itself by using PPP BCP.  
Normally, two IP routers would negotiate PPP IPCP to exchange IP  
packets.  
However, if a device can only support PPP BCP, IP packets are en-  
capsulated by the device as bridge packets. The Router Option  
Module can treat the WAN IP Bridge as a virtual Ethernet port con-  
nected only to a WAN device which has negotiated PPP BCP. This  
menu allows the IP parameters for this virtual Ethernet to be set up.

WAN IP Bridge/Triggered  
Write security: 2; Read security: 5  
When set to Yes, only IP RIP updates are sent when the routing table  
has changed. When set to No (def), updates are sent periodically.  
RIP version, method, and direction are determined by the Ethernet  
parameters set in the Configuration/IP/IP Router/RIP menu.  
WAN IP Bridge/Proxy ARP  
If this option is set to Yes (def), the Router Option Module will  
proxy ARP on the bridge IP port. See the section IP/Proxy ARP on  
page page 4-9 for an explanation of the proxy ARP function.  
Bridge/WAN IPX Bridge  
When IPX routing is active, the Router Option Module will allow  
another WAN device to bridge IPX packets to it using PPP BCP.  
Normally, two IPX routers would negotiate PPP IPXCP to exchange  
IPX packets. However, if a device can support only PPP BCP, IPX  
packets are encapsulated by the device as bridge packets. The Rout-

Security/PPP  
Write security: 1; Read security: 2  
The PPP peer can be authenticated using three standard methods:  
1. PAP (Password Authentication Protocol),  
2. CHAP (Challenge Handshake Protocol)  
3. EAP (Extensible Authentication Protocol).  
The strength of the authentication is determined in the following or-  
der:  
1. EAP  
2. CHAP  
3. PAP (where EAP is the strongest and PAP is the weakest)  
PAP is a clear-text protocol, which means it is sent over the PPP link  
in a readable format.  
Do not allow highly sensitive passwords to become compromised using this  
method.  
CHAP and EAP use a one-way hashing algorithm which makes it  
virtually impossible to determine the password. EAP has other ca-  
pabilities which allow more flexibility than CHAP.  
The following selections are possible:  
PAP, CHAP or EAP (def) - The Router Option Module will ask for  
EAP during the first PPP LCP negotiation and allow the PPP peer to  
negotiate down to CHAP or PAP.  
CHAP or EAP - The Router Option Module will ask for EAP during  
the first PPP LCP negotiation and allow the PPP peer to negotiate  
down to CHAP but not PAP.  
EAP - The Router Option Module will only allow EAP to be negoti-  
ated. If the PPP peer is not capable of doing EAP, then the connec-  
tion will not succeed.

Frame Relay  
(also available via Front Panel)  
Frame Relay is a connection-oriented service requiring circuits to be  
configured by your carrier to establish a physical link between two  
or more locations. Multiple virtual circuits (which appear as virtual  
point-to-point links) can be run through the same physical connec-  
tion.  
There are two types of virtual circuits supported in Frame Relay:  
Virtual Circuit Types  
Description  
Permanent Virtual Circuits PVCs are like dedicated point-to-point  
(PVC)  
private lines.  
Since the physical connection is always  
there in the form of a leased line, call  
setup and tear down is done by a car-  
rier via a network management sys-  
tem.  
Virtually all Frame Relay communica-  
tion is done using PVCs.  
Switched Virtual Circuit  
(SVC)  
SVCs require setup and tear down and  
are generally not available from Frame  
Relay carriers.  
The Router Option Module supports PVCs only.  
The Data Link Connection Identifier (DLCI) number identifies each  
virtual circuit within a shared physical channel.

ification.  
Static  
Select when there is no Frame Relay switch in  
the circuit. The DLCIs are assigned in the DLCI  
Mapping and must be the same for the device it  
will communicate with.  
Frame Relay/Polling Frequency  
Write security: 3, Read security: 5  
This parameter is the interval that the Router Option Module polls  
the Frame Relay switch using the maintenance protocol selected  
above. The Router Option Module is required to poll the Frame Re-  
lay switch periodically to determine whether the link is active. The  
value is in seconds and ranges from 5 to 30 seconds.  
Frame Relay/DLCI Mapping  
This menu allows each DLCI to be mapped to a particular protocol.  
Each protocol parameter can be individually configured for each  
DLCI. By factory default, the DLCI map is empty.  
When empty and a maintenance protocol other than static is used,  
the Router Option Module will poll the switch to determine which  
DLCIs are active. These active DLCIs will attempt to determine the  
IP and IPX addresses on the other end of the virtual circuit using In-  
verse ARP (IARP). If there is a response, the network learned will be  
added to the router tables and the virtual circuit will be treated as an  
unnumbered interface. Bridge mode is not attempted in this case.

Chapter 4: Configuration Overview  
When more than one DLCI mapping is listed, the Router Option  
Module will try to match the DLCIs learned from the Frame Relay  
switch with the DLCI values in the map. If there is a match, the pro-  
tocols specified in the map are used. However, if an active DLCI is  
not in the list, the Router Option Module falls back to using IARP as  
in the above paragraph to determine the protocols to use with that  
particular virtual circuit.  
If a static maintenance protocol is used, at least one DLCI mapping  
must be specified.

DLCI Mapping/Bridge Map  
This menu is used to permit bridging of packets over this DLCI.  
Each DLCI or virtual circuit must be assigned a bridge group. The  
bridge group treats all virtual circuits as one circuit. Bridge packets  
destined to be transmitted out a particular bridge group are copied  
and transmitted individually out each DLCI in the bridge group.  
However, incoming bridge packets received from one DLCI are not  
retransmitted out the other DLCIs in the same bridge group. Any  
device in the bridge group must transmit to each DLCI. This re-  
quires a fully meshed circuit, meaning each device has a virtual cir-  
cuit to each other.  
Bridge Map/Active  
Write security: 3, Read security: 5  
When set to Yes (def), the Router Option Module will bridge pack-  
ets to and from this DLCI. Bridge packets are any packets that are

net. The Ethernet network can consist of private network numbers.  
When this profile is connected, all IP addresses on the Ethernet side  
are translated into the one real IP address negotiated with the PPP  
peer (ISP). Multiple stations on the Ethernet side can access the In-  
ternet simultaneously. See the section IP/NAT on page page 4-7 for  
more global options.  
When set to On, the Router Option Module to perform NAT.  
When set to Off (def), the unit will route across the connection nor-

an unnumbered link. This is usually referred to as being a “half-  
router.” However, a PPP peer which wants to assign a network ad-  
dress to the WAN link can do so, in which case the Router Option  
Module will go into “full-router” mode.

61200350L1-1  
Router Option Module User Manual  
4-39  
 
Chapter 4: Configuration Overview  
The Type 20 IPX packet is used specifically for this purpose. This  
causes special handling of this packet by the Router Option Module.  
When a router receives this type of packet, it rebroadcasts it across  
all interfaces except the one it is received on and includes the net-  
work number of that interface in the data portion of the packet.  
The IPX Router Specification from Novell notes that Type 20 packets  
should not be propagated across slower links with bandwidths of  
less than 1 Mbps (like ISDN). However, when set to Pass (def), the  
Router Option Module will allow these packets to propagate over  
the WAN connection. This facilitates dial-on-demand applications.  
When set to Block, all Type 20 packets are not propagated across the  
WAN connection.  
PPP Profile/Bridge  
The Bridge menu contains the parameters needed for exchanging  
bridged packets with the PPP peer.  
Bridge/Mode

route mode only if the PPP peer cannot support certain PPP proto-  
cols for that particular routing protocol. See Bridge/WAN IP Bridge  
and Bridge/WAN IPX Bridge on page page 4-14 for further details.

Upgrade/Transfer Method  
The two methods for upgrading are TFTP and XMODEM.  
1. TFTP requires a TFTP server running somewhere on the net-  
work. The Router Option Module starts a TFTP client function  
which gets the upgrade code from the TFTP server.  
2. Selecting XMODEM will load the upgrade code through the  
maintenance port using any PC terminal emulator with XMO-  
DEM capability.  
Upgrade/TFTP Host  
This is required when the transfer method is TFTP. It is the IP ad-  
dress or domain name (if DNS is configured) of the TFTP server.  
Upgrade/Filename  
This is required when the transfer method is TFTP. It is the case-sen-  
sitive filename which is the upgrade code.  
Upgrade/Status  
This appears when TFTP is used. It displays the status of the trans-  
fer as it happens. Any error or success message will be displayed  
here.  
Upgrade/Start Transfer  
This activator is used when the configurable items in this menu are  
complete.  
Once started, the Router Option Module will prompt for erasing the flash.  
When the flash is erased and the upgrade transfer fails, do not turn off the  
unit. Retry the transfer until successful. Otherwise, if power is removed  
before upgrade has finished, the upgrade will have to occur from the  
maintenance port using XMODEM. If this happens, set a PC terminal  
emulation program to 9600 baud and attach to the Router Option  
Module’s maintenance port. Press Return to display a simple terminal  
menu for upgrading. This menu appears when the flash code has been  
erased or is corrupt. The menu will also appear if you power up and hold  
down the SELECT key for at least five seconds.

Negot not converging  
level 2  
Negotiation of the LCP layer is unattainable due to misconfigura-  
tion or the Router Option Module or PPP peer is requiring authen-  
tication and the other is refusing.  
No IP addr for peer  
level 2  
The Router Option Module cannot continue the connection be-  
cause there was no IP address received from the PPP peer or it was  
not set in Configuration/Connection List/IP/Route/IP/Net pa-  
rameter.  
No Response from peer  
level 2  
The Router Option Module has dialed or answered a call and no  
PPP negotiation packets were seen.

The PPP peer has rejected the Router Option Module’s username  
and/or password used for authenticating. Check to make sure the  
Configuration/Connection List/Authentication parameters Tx  
Method, Tx Username, and Tx Password are correct.  
Peer failed CHAP authen  
level 3  
The PPP peer’s reported CHAP username and/or password does  
not match the Router Option Module’s parameters. This is most  
likely caused by PPP peer sending an incorrect username and/or  
password. Make sure the Configuration/Connection List/Au-  
thentication parameters Rx Username and Rx Password are cor-  
rectly entered. Also, if using RADIUS, check that the server is  
configured and running properly.  
Peer failed EAP authen  
level 3  
The PPP peer’s reported EAP username and/or password does  
not match the Router Option Module’s parameters. This is most  
likely caused by PPP peer sending incorrect username and/or  
password. Make sure the Configuration/Connection List/Au-  
thentication parameters Rx Username and Rx Password are cor-  
rectly entered. Also, if using RADIUS, check that the server is  
configured and running properly.

SNMP  
Appendix D  
UNDERSTANDING SNMP  
The Simple Network Management Protocol (SNMP) is the de facto  
standard for managing commercial Transmission Control Proto-  
col/Internet Protocol (TCP/IP) networks. It allows vendor equip-  
ment to be managed from a single control console.  
The term SNMP broadly refers to the message protocols used to  
exchange information between the network and the managed de-  
vices, as well as to the structure of network management databas-  
es.  
SNMP Components:  
SNMP has three basic components: Network Manager, Agent,  
and MIB.  
Network Manager  
• A control program that collects, controls, and presents data  
pertinent to the operation of the network devices.  
• Resides on a network management station.  
Agent  
• A control program that responds to queries and commands  
from the network manager.  
• Returns requested information or invokes configuration  
changes initiated by the manager.  
• Resides in each network device connected.  
61200350L1-1  
Router Option Module User Guide  
D-1  
 
Appendix D: SNMP  
MIB  
• An index to the organized data within a network device.  
• Defines the operating parameters that can be controlled or  
monitored.  
When requesting the network manager to retrieve or modify a  
particular piece of information about a network device, the net-  
work manager transmits the request to that network device. The  
agent in that device interprets the incoming request, performs the  
requested task, and sends its response to the network manager.  
The network manager collects all the data from the various net-  
work devices and presents it in a consistent form.  
Using SNMP Version 1, the network manager can issue three  
types of commands:  
GetRequest: This command retrieves a single item or the first in  
a series from a network device.  
GetNextRequest: This command retrieves the next item in a se-  
ries from a network device.  
SetRequest: This command writes information to a network de-  
vice.  
The network device issues two types of messages:  
GetResponse: This message is the response to a network manag-  
er GetRequest or GetNextRequest command.  
Trap: This is an unsolicited message issued by a network device  
to report an operational anomaly or an alarm condition to the net-  
work manager.  
These messages are typically encased within informational pack-  
ets and transported over the LAN or WAN.

Appendix D: SNMP  
SNMP Embedded Agent  
The Router Option Module supports the following groups from  
MIB-II (RFC 1213):  
• System Group  
• UDP Group  
• Interfaces Group  
• ICMP Group  
• Address Translation Group  
• IP Group  
• TCP Group  
Also, the Ethernet transmission MIB is supported (RFC 1643).  
The following manager requests are supported:  
• Get object  
• Get next object  
• Set object  
Communities  
The Router Option Module permits up to eight communities to be  
defined. The privilege level of each community can be set. The de-  
fault community is public with read-only privileges. When the IP  
address is all zeros, any manager of the community can access the  
Router Option Module.  
Traps  
Up to four hosts can be set to receive traps. Each host entry re-  
quires an IP address of the manager.

nal screen for capture.  
Download/Uploading Configuration  
The Router Option Module’s configuration can be captured to a  
text file using the download command. The text file can be edited  
if required.  
Uploading the configuration can be accomplished by sending the  
text file to the Router Option Module in terminal mode. A baud  
rate of 9600 is strongly recommended when uploading. As soon as  
the upload has been completed, type Save to save the new config-  
uration to flash.  
A reset command or power up cycle 10 seconds after the save  
command is recommended to ensure that the new configuration  
is complete.
