Connecting Cisco 3660 (VWIC-2MFT-E1)

Greetings Cisco Experts,

I’m trying to connect two Cisco 3660 back-back using VWIC-2MFT-E1 (RJ 48 cross over)

Cisco 3660(VWIC-2MFT-E1)=====(VWIC-2MFT-E1)Cisco3660

One of the VWIC-2MFT-E1 is in the 2W slot and the other is in the 2FE-2W slot

But for some reasons both of them are not talking to each other and I’m getting

A lot of slip alarms on the controllers

Following is the simple config of both routers

Router 1

controller E1 5/0

shutdown

framing NO-CRC4

clock source free-running

!

controller E1 5/1

framing NO-CRC4

clock source internal

channel-group 1 timeslots 1-31

!

interface FastEthernet0/0

no ip address

shutdown

router eigrp 1

no eigrp log-neighbor-changes

!

E1 5/1 is up.

Applique type is Channelized E1 - balanced

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20000922, FPGA: 15

Framing is NO-CRC4, Line Code is HDB3, Clock Source is Internal.

Current port master clock: local osc on this network module

Data in current interval (191 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations
