This will allow your current brouter to support ATM, simply by supporting V.35 and High - 3Com 3C63313 | Reference Guide - Page 250
S330/S310 MODULE AND APPLICATION OVERVIEW The DXI protocol itself is based on HDLC and provides the mapping within the HDLC frame to place the router data on an appropriate VC. (See Figure 172.)

an ATM network to the DXI mode 1A device (PathBuilder S330/S310 serial interface), which then will perform SAR and AAL5 mapping to an ATM PVC. It provides simple and efficient encapsulation of your service data unit and supports AAL5 transit encapsulation. (See Figure 174.) Figure 174 DXI Format - 3Com 3C63313 | Reference Guide - Page 252

You could use the HDLC service for router to router and X.25 to X.25 links. You could use the SDLC service for IBM FID2 3270 SNA Peripheral or IBM FID4 372X - 3Com 3C63313 | Reference Guide - Page 254
