MTASR1-100 Sync Mode Test Product Update
PN S0000091, Rev. A
6/13/00
The RouteFinderModel MTASR1-100 is a 1-Port 10BaseT/10Base2 Router for the Global market. The
following is a procedure for testing an MTASR1-100 router and the composite link cable in synchronous
mode. Multi-Tech routers will connect to themselves and proceed to send packets into a modem in
synchronous loopback mode and receive the same packets back.
Synchronous Mode Test Procedure
Router Configuration
1. Start the RouteFinder configuration software, and access the MTASR1-100. The following are the
special settings needed for this test.
2. Click the “IP” button, and then access the “Ethernet” tab. Verify that a valid IP address is assigned to
the Ethernet port of the MTASR1-100 router, and that Authentication is set to “No Authentication.”
3. Click the WAN tab. Check “IP Port Enable” and “Unnumbered Link.”
4. Click the Advanced tab. Check “Routing”, and uncheck “RIP.” Click “OK” to return to the main
configuration screen.
5. Click the “PPP/SLIP” button, and then access the “WAN” tab. At the bottom of the window, check
“Client or LAN” for Remote Port Setup. Click “OK” to return to the main configuration screen.
6. Click the “WAN” button, and then access the “WAN” tab. Check “Port Enable.” Under “Mode”,
check “synchronous”, “external clock”, “Send Idle Flags.” Under “Connection Method”, check
“Direct Connect/Lease Line.” Click “OK” to return to the main configuration screen.
7. Click the “Frame Relay” button, and uncheck the “Enable” box. Click “OK” button to return to the
main configuration screen.
8. Click “Download Setup” to load the new settings into the MTASR1-100 router. Switch the MTASR1-
100 router off.
Modem Configuration and Setup
9. Disconnect the MT2834BLI modem attached to the MTASR1-100 modem from the lease line.
10. Set the MT2834BLI modem to the following DIP switch settings: SW1 and 11 down; SW2-10,
SW12-16 up.
11. Turn the MT2834BLI modem off.
12. Hold the Ans/Org (Voice/Data) switch on the modem in the down position. While continuously
holding the Ans/Org switch in the down position, switch the MT2834BLI modem back on.
13. Continue to hold Ans/Org switch in the down position until five seconds after the modem lights have
ceased to cycle.
14. The CD and TR lights, plus a speed light (probably a 33 light, flashing) on the modem will light. The
MT2834BLI modem is now in loopback mode, using synchronous data protocol. Data sent to the
modem will be sent directly back to device attached to the modem.

Testing the Composite Link cable
15. Switch the MTASR1-100 router back on. Wait for the MTASR1-100 router to cold reboot.
16. Immediately after the MTASR1-100 router has rebooted, the RCV, XMT, CTS, RTS, CD lights in the
WAN Link panel should all light. If only the CTS, RTS and CD lights go on, the cable between the
MTASR1-100 router and the MT2834BLI modem does not support synchronous communications.
Replace it with a cable supplying pins 15 and 17, like the Multi-Tech composite link cable, available
from Multi-Tech value-added resellers.
Testing the MTASR1-100 Router
17. Connect the MTASR1-100 router to an Ethernet hub.
18. Open a telnet session to the router over Ethernet. Choose option “2”, “Router Management.”
19. Choose “1”, “Router Statistics.”
20. Choose “6”, “PPP Statistics”, then “1”, “WAN”PPP port.
21. The first statistics to appear will be the LCP (Link Control Protocol) Statistics. You should see 3 or 4
packets and between 50-100 bytes, being transmitted and received. There should be no errors, etc.
These statistics will not change so long as the router maintains communication through the modem.
Hit the “Enter”key to continue.
22. Next to appear will be the NCP (Network Control Protocol) Statistics. Separate sets of NCP statistics
will be displayed for the IPX and IP protocols, depending on whether either protocol has been enabled.
If LCP and NCP have both been established, then PPP has been established and the IPX/SPX and/or
TCP/IP protocols can be established.
23. The remainder of the Telnet menus will permit you to check whether or not the TCP/IP and IPX
protocols are functioning properly and also whether RIP is working right. You can test the TCP/IP
functionality by using the “ping {router address} -t”MS-DOS command to continually send TCP/IP
packets to the router and receive the echoes.
