Re: G.703 -> V.35 Compatibility

Hi Ranjith,

Yes they will work, however, could you confirm what cable you are using
on the router with the V.35 interface.
The serial adapter cables determine the mode and interface type, for
example it will become a DTE when a DTE cable is connected to it. To use
the port as a DCE interface, you must set the clock rate and connect a
DCE cable.

Perform a "show controller slot/port" on the router with the V.35
interface, this will show you what type of cable is physically connected.

Note that if a DTE cable is connected to the port with a clock rate set,
the DTE ignores the clock rate and uses the external clock signal that
is sent from the remote DCE. The maximum recommended rate for a V.35
serial interface is 2048Kbps with a maximum distance of 25 feet or 8 meters.

regards Andy
