Verify that the identifier on the interface is correct so that you connect the
interfaces correctly and prevent damage to the interface module or router.
To connect the cable:
1 Determine which interface in the 4-Port ISDN S/T MIM will be connected using the
cable.
2 Power off the router.
3 Confirm the ISDN type provided by the telecom carrier.
4 Connect the cable.
■
If the line is an ISDN U interface line, adapt it to the NT1 by plugging one end
of the S/T interface cable to the S/T interface of the NT1 and the other end to
the BRI interface of the 4-Port ISDN S/T MIM.
■
If the line is an ISDN BRI S/T interface line, connect the cable directly to the BRI
interface of the 4-Port ISDN S/T MIM.
5 Power on the router and check the status of the READY LED on the faceplate of
the module. If the LED is on after the POST, the module is operating normally. If
the LED remains off after the POST, the module failed and you should contact your
Service representative.
Encryption Accelerator
MIM
The Encryption Accelerator MIM supports IPSec protocol, accelerates the
encryption processing of IP packets through the hardware, and provides the router
with high-performance, high-reliability encryption capabilities.
The Encryption Accelerator MIM can be installed in any of the Router 5000.
When the Encryption Accelerator MIM is installed in a Router 5000 Family, the
router routes and forwards the IP packets and implements VPN with encryption
features. Figure 52 illustrates the Encryption Accelerator MIM.
