The 5.x CPU includes four controllers for use in various types of communication. All four
controllers are mapped through two TSA (Time Slot Assigner) devices and will share a
common pool of 64 time slots. The TSAs are cross-connected to the TDM (Time Division
Multiplexing) bus via MTUSs (Memory Time Switches).
Currently, the four nx64 ports can only be assigned to WAN resources.
The four available channels may be configured at nx64 kpbs, using plain HDLC for
communication with other Integrated Access Systems, or using RFC1490 encapsulation for
connectivity to other Integrated Access Systems as well as the Frame Relay public network.
