We have an old 3725 router with a HSSI card connected to a DL3100, which in turn is connected to a subrate DS3 circuit. The plan is to replace the router with a new 2951 router and a NM-T3/E3 card.
After the router was replaced, I configured the NM but the circuit remained dow/down. I'm sure it has to do with the fact that the DS3 circuit is channalized but I'm not sure how to configure this module to be channalized. Here is the configuration that I placed on the router:
controller T3 1/0
clock source line
no ip address
encapsulation frame-relay IETF
frame-relay lmi-type cisco
dsu bandwidth 10240
dsu mode 0
interface Serial1/0.105 point-to-point
ip address 10.10.10.1 255.255.255.252
frame-relay interface-dlci 105 IETF
Any help would be appreciated.
It is very unlikely that the circuit is channelized.
Plese post "show controllers T3". to get the circuit up you must know the correct framing, dsu mode and dsu bandwitdh values. If do not have these, ask telco.
Thanks for the quick response.
I do not have access to the router at this time but I can tell you that the framinng is set to "c-bit", the dsu mode is set to "dsu mode 0", which is for a digilink mux and finally the dsu bandwidth is set to 10240.
I just learned from the Telco that the circuit is using M13 framing. Would you know how to configure the NM-T3/E3 for M13 framing?
you can try following configuration:-
I hope framing is m23 instead of m13.
