7. Configuring Frame Relay/PPP And T1/E1

RX1000/RX1100™

Once all timeslots have been assigned to channels, the “Timeslots..” link will no longer appear. Note
that you do not have to assign all timeslots.

Assign Frame Relay or PPP to the channels by following the “Assign .. Protocol” links. The resultant
menus will allow you select the desired channel.

If you are assigning multiple DLCIs, assign the first DLCI used by that interface and configure the
Frame Relay Link Parameters and that DLCIs network parameters.

After assigning the first DLCI, you may revisit the interface through the link under the Name field and
add additional DLCIs.

Once all channels have been assigned, the “Assign” links will no longer appear, as shown below.
Note that any of the Frame Relay interfaces on a channel (in this case w1c4fr16 and w1c4fr17) may
be used to edit the Frame Relay Link Parameters.

7.2.1.2. Naming Of Logical Interfaces

Webmin names the logical interfaces for you (but allows you to provide a description). All interfaces
start with a "w" to identify them as wan interfaces, followed by the physical interface number.

Unchannelized hardware interfaces supply only one channel (that can be composed of a varying
number of timeslots) logical interface. You may configure one PPP interface or up to 992 Frame Relay
DLCI interfaces. The next part of the identifier is either "ppp" or "frX" where X the frame relay channel
number.

Channelized hardware allows more than one logical interface. The next part of the identifier indicates
the channel the interface uses with a "c" followed by the lowest channel used. The final part of the
identifier is either "ppp" or "fr" and the frame relay channel number.
