Help with 2-port T1 Wic config... 3

[jason985]

I need some help configuring 2 port t1 WIC (VWIC-2MFT-T1)on my 2620 router. This is my first time trying to configure the 2 port T1 WIC. What I am trying to do is setup the WIC with two separate point to point T1 lines. This is for two remote branches to connect back to my main branch. I need to configure both ports to use HDLC and b8rz. I need one of the ports ip to be 192.168.0.13 and the other port to use ip 192.168.0.11. Any help with the configuration would be greatly appreciated.

This is what I configured so far. Would this be right?
controller T1 0/1
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24 speed 64
!
controller T1 0/2
framing esf
clock source internal
linecode b8zs
channel-group 0 timeslots 1-24 speed 64

Here's my config from a 2691 with 2x VWIC-2MFT-T1 cards in it, all point to point DS1s (basically identical to yours, except we have 4 T1s, and there is some stuff in there for our VOIP system. Looks like you're in good shape. Hope it helps (I've munged our info):

Oh, and make sure that on your remote sites, you put

clock source line

since they'll get clocking from your home office router.

 

[jason985]

jpm121,


Thanks for the help. Quick question what should my remote site routers state for the clock source line?


TIA

 

[jpm121]

Jason, that's what I meant with my added comment -- the remote routers should have:

clock source line

(which means, "I'll find the clock source coming over the T1 line, out there somewhere.")

On your dual T1 router (the one I showed above), it says "I'm in charge of providing clocking for this T1, because of the 'clock source internal' statement."

(Check with your provider -- for point-to-points, most of them do not provide clocking, but it's better to be sure.)

 

[jason985]

Jpm,

Thanks for all the help, I should be ready now for the new T1 to be installed. I really appreciate the help!

Jason

 

[jpm121]

Sure thing, good luck.

 

[Cluebird]

jpm121 I'll give you the star since you earned it.

 

[jason985]

Make that TWO stars!

Great post, but I have a quick of quick questions:

1)Don't you need to indentify the card in the config (i.e. card type T1 1)?

2) Does he actually need to add clock source line? If he removes clock source internal, isn't line the default?

 

[Sindee]

>> Great post, but I have a quick of quick questions:


Sorry about the typo in the above post. It was suppose to be a couple of quick questions.

 

[jpm121]

Sindee, the router knows which is which based on where they are in the slots, and the type of card. Always starts at zero, and goes up (in my case from right to left looking at the back of the 2691 router).

For your second question, I'm not 100% sure if the "clock source line" is explicitly required on the remote routers, but it's definitely required for the router providing timing. By putting it on the remote router as well I immediately know where the clocking is in case we change the network config in the future.
