Cisco 2950 & 2960 with Zhone 2040G

[Bleuvert]

Hi,
i recently connect two switch 2950 and 2960 with two zhone 2040G SHDSL nerwork extender ( 2.3 Mbps x 4 = 9.2 Mbps ). I have a lot of problem with this connection. The 2 switchs was configure to communicate as trunking dot1q, and each one was connect to an Zhone ( paradyne ) SNE2040G between us. I have 20 PC connect to the end of the line switch (2960) and the trunking port FA0/24 link to the modem blink green-amber-green-amber-... a lot of the time, a sign of a link fault. Any difference between SNE2040G provider and subscriber unit??? i see different sticker on the the two boxes, but a did'nt see any difference between the unit. Please thank's for your precious help.

I'd recommend checking the logs on your 2950, 2960 and the Zhones to see if there is any indication of an issue on the uplink ports to the Zhone devices. Do you need to trunk between the Zhone and the Cisco switches?
