Cisco ATA188

[billberge]

Folks,

I have limited ports available in certain locations of my building so I have to improvise in order to get all network devices on the LAN.

What I have done is hooked one of my Cisco ATA 188’s into the office wall port which is hard wired to my MDF and cross connected to my Cisco 4510. On one of the ATA FXS ports I have hung a fax machine which works fine. The other FXS port is empty. I then daisy chained a Cisco 7940 off of the ATA’s RJ45 switchport and hung a pc off of the phone. Everything appears works fine. However, when I logged into my core switch I noticed a duplex mismatch between the phone and the switch. This is quite odd because the ATA itself is connected at 100 Mbps full which is really the neighbor of the 4510. When I look at the phone is shows it is connected at 10 Mbps half. I’ve tried browsing to the ip addressed of both the phone and the ATA to see if I can somehow hard code the phone or ATA switchport to 100 full.

Has anyone else ever tired to do this and is there a solution?

Thanks……..

I've never had quite a setup like this before, but I *have* had success with the phone being the first device in line to the core switch. The phone, in essence, is a 3-port switch with one port going to the phone itself, one-port going to the uplink and on-port going to the PC, or down-link. The ATA's are only going to have limited configurability. Remember, these are not Cisco originals here, but rather purchased from another company. The name escapes me at the moment.

Thanks John. I changed the setup to the way you mentioned and all devices are not connected at 100 full.
