Trying to install two 2950LRE (8 ports) switches back-to-back on LRE (long reach ethernet).

Is it possible?

If yes, should the cables/wires be crossover or straight-through?

Q. Is it possible to connect two Cisco 575 LRE CPEs back-to-back?

No, you cannot connect two Cisco 575 LRE CPEs back-to-back. Also, you cannot connect two Cisco 2900 LRE XL switches back-to-back via the LRE ports.

The Cisco LRE product is a very-high-data-rate digital subscriber line (VDSL) based product so the Transmit (TX) and Receive (RX) use different frequency bands. The Cisco 575 CPE uses the opposite frequency band for transmission/reception compared to the Cisco 2900 LRE XL switch.

Note: There is no crossover cable for this product. The connection must be between the Cisco 575 LRE CPE and the 2900 LRE XL switch.
