1. Channelized bandwidth with Hybrid Access Hybrid Access cards provide the HDLC processing required for packetized data sent and received on the channelized T1 T3 or E1 cards Call routing profiles route inbound data to a terminating Hybrid Access channel Outbound data is routed first to a Hybrid Access card to be packetized before being transmitted on the T1 or E1 line Note Because some terminating cards such as the Series56 II and Series56 II modems or the MultiDSP cards perform HDLC processing but do not support Frame Relay you should APX 8000 MAX TNT DSLTNT Frame Relay Configuration Guide 2 1 Physical Interface Considerations Channelized bandwidth with Hybrid Access be aware of special call routing considerations if the TAOS unit has both modems and Hybrid Access cards installed and you are using channelized bandwidth for Frame Relay For details see the APX 8000 MAX TNT DSLTNT Physical Interface Configuration Guide When configuring nailed bandwidth for Frame Relay the number of channels you configure in the TAOS unit should match the number of channels used by the device at the other end of the link In addition make sure that only one line profile specifies the Nailed Group number to be used by the Frame Relay data link Example of configuring nailed T1 In the following example the T1 line is configured for nailed usage with a group number of 13 Channels bound to a nailed group must be contiguous
