I've got three cisco 1721's and a 2610, two of the 1721's are 32f's, the other one is a bit older but is still the same model.
The two cisco 1721 32f's have 1-dsu-t1-v2 wics in them, and the older 1721 has a 1-dsu-t1 wic in it. Now no matter how i have configured it the old t1 wic will not talk to the v2 wic. I've tried putting the old wic into a 1721 32f and it doesnt work at all!
Let me try to make it a bit clearer for you
What i have working:
router DCE (1721 32f with v2 wic) can talk to router DTE (1721 32f with v2 wic) no problem with this configuration.
Router DCE:
service-module t1 clock source internal
service-module t1 data-coding normal
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
no service-module t1 fdl
ip address 10.10.10.10 255.0.0.0
no shutdown
Router DTE:
service-module t1 clock source line
service-module t1 data-coding normal
service-module t1 timeslots 1-24 speed 64
service-module t1 framing esf
service-module t1 linecode b8zs
no service-module t1 fdl
ip address 10.10.10.11 255.0.0.0
no shutdown
Router OLD (1721 with v2 wic) can talk to router DTE (1721 32f with v2 wic) no problem with same config
What doesnt work:
Any router with 1-dsu-t1 (old) wic to router DTE (1721 32f with v2 wic)
again same configuration as before, so whats going on that i cant get this to work? Is the old t1 wic not compatible with the new t1 wic?
If you have any questions or need pics to help explain the issue i can provide them
