48 CHAPTER 3: INTRODUCING ROUTER 5000 F AMILY MIM SVerify that the identifier on the interface is correct so that you connect theinterfaces 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 thecable.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 endof the S/T interface cable to the S/T interface of the NT1 and the other end tothe 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 BRIinterface of the 4-Port ISDN S/T MIM.5 Power on the router and check the status of the READY LED on the faceplate ofthe module. If the LED is on after the POST, the module is operating normally. Ifthe LED remains off after the POST, the module failed and you should contact yourService representative.Encryption AcceleratorMIMThe Encryption Accelerator MIM supports IPSec protocol, accelerates theencryption processing of IP packets through the hardware, and provides the routerwith 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, therouter routes and forwards the IP packets and implements VPN with encryptionfeatures. Figure 52 illustrates the Encryption Accelerator MIM.Figure 52 The Encryption Accelerator MIM
