Which devices can handle a WAN link over private copper pair (no clock signal provided by Telco)

[eagletec1]

Which small business Cisco devices would I need to create a WAN link from point to point over a private copper pair (or 2 pairs if required). The Telco is providing the point to point copper link which will not be connecting to there equipment so will have no IP addressing or clock signal. Will I need to use a device with a serial interface or do some of the RJ45 type units have DCE/DTE capability? The main office will have two WAN links to two remote offices which are both around 3.5km (cable lenght) away. I looking at the 880 series but I'm unsure if these units can perform the required task.

Hello Louise,

SHDSL symmetric DSL or SDSL can be used for this with one device configured to act as CO.

Great. So will the 888-K9 will be suitable?

Hello Louise,

yes because the 888 has the right xDSL type installed

Hi Giuseppe,

Thanks for your help.

Would know what the maxium distance the 888 can handle not that 3.5kn should be an issue?

Hello Louise,

they should be able to work, they may need to negotiate and use a reduced bit rate to have a good noise margin.

It depends from line conditions.
