Hello,

Im bit confused about this command after reading a configuration document in cisco site.

Correct me if Im wrong but my understanding on this command is that it enables DDR on async and serial interface, since this interfaces are non-native ISDN ( Doesnt have a D-channel ). Is it also possible to add this command to a native ISDN such as BRI interface or to a dialer profiles that is being bind to a bri interface? Does adding this command to a native isdn interface has no bearing at all.. that result to an optional command ?

this is considered a legacy ddr spoke command

dialer in-band
To specify that dial-on-demand routing (DDR) is to be supported, use the dialer in-band interface configuration command. To disable DDR for the interface, use the no form of this command.

dialer in-band [no-parity | odd-parity]
no dialer in-band

no-parity
(Optional) Indicates that no parity is to be applied to the dialer string that is sent out to the modem on synchronous interfaces.

odd-parity
(Optional) Indicates that the dialed number has odd parity (7-bit ASCII characters with the eighth bit as the parity bit) on synchronous interfaces.

Thanks for the reply, So are you saying that this command has nothing to do with the control D-Channel and I could use it to a native and non native ISDN interface ?

Thanks in advance

correct. ddr just brings the line up when interesting traffic comes through regardless of interface type.

There are also modular interfaces for routers you can purchase that has integrated NT1 in the BRI interface therefore allowing you to connect to a U interface. It should say BRI U. If it says BRI S/T then you need an NT1.
