ATT Fiber Ring 50MB line - no negotiating


Firstly the situation we have here is that we are on the outskirts of an ATT Fiber Ring and we have servers currently hosted at an ATT Datacenter. They stated we could hop on that fiber box with their help and get a 50MB link to our cage in the datacenter...great news huh? They also stated that they would give us an Ethernet handoff...well they didn't...fiber instead. So we went out and bought 2 3560G with GBICs, one for each end. We tested the switches inside the office with a fiber cable and everything was fine.

So then we hooked up these switches to the Cisco ONS 15327 and ATT repeatedly told us that the circuit was problem...great. Still no data...they said just hook them up and ping...nothing else to configure. We did this and nothing happened. Also when doing a "show int gig0/49" we get line down and no lights on the outside of the GBIC on the 3560G. But when we flip the fiber cables the wrong way the 15327 seems to respond so there doesn't seem to be anything physically wrong with our setup.

I'm not terribly great with these things but ATT is not helping us at all. They said they have no Cisco techs that could help us...don't know why...seems pretty simple to me...we must be missing some sort of protocol or something for the handshake that isn't happening. I have included a copy of the configs maybe someone out there can at least shine some light before we tell ATT to shove it.

Thank you

The Cisco ONS 15305 transports Ethernet and TDM traffic inside an SDH frame for metropolitan-area network (MAN or metro) applications. The Cisco ONS 15305 can be used as customer premises equipment (CPE) for medium- and large-sized businesses - collecting voice and data traffic from each site for switched voiced and data services, Layer 1 and Layer 2 VPNs, and Internet access - for transport over an STM-1, STM-4, or STM-16 SDH uplink to the central office. The Cisco ONS 15305 can also be deployed as a central office aggregator; consolidating STM-1 access links from Cisco ONS 15302 Multiservice Provisioning Platforms or other Cisco ONS 15305 CPE, as well as directly connected customer TDM or data traffic from electrical interfaces
