3640 with HSSI and External CSU/DSU - Fractional T3

[t.khan]

Can anyone provide assistance on how to configure a 3640 with a HSSI card to talk to a Kentrox CSU/DSU for a fractional T3?

I have the info on the Kentrox as:

Kentrox: DSUCLK:3.0,3.0

For a 3Mb frac.

Thanks

Here's a config example for you.

interface Hssi1/1

description HSSI to NYC3725-2 H1/0

bandwidth 30709

ip address 10.254.253.2 255.255.255.252

ip pim sparse-dense-mode

serial restart-delay 0

hold-queue 250 out

You'll want to change the bandwidth statement and remove PIM. The config is staight forward.

HTH and please rate.
