am186?cc microcontroller isdn ta reference design manual ix about the am186 ? cc microcontroller isdn ta reference design the am186cc microcontroller isdn terminal adapter (ta) reference design is a small, cost-effective isdn solution for embedded communications applications. this design is intended to reduce the time to market for isdn designers using the am186cc microcontroller. figure 0-1 shows a block diagram of the isdn ta reference design. the isdn ta reference design is a functional isdn ta that illustrates the benefits of using the am186cc microcontroller. the am186cc microcontroller has a number of integrated features required in many communication applications. these features include four high-level data link control (hdlc) channels and a universal serial bus (usb) peripheral controller with an internal transceiver. the hdlc channels support gci/iom-2, pcm, and dce interfaces. other integrated features include four general-purpose dma channels, eight smartdma? channels, four time-slot assigners (tsas), one uart, one high-speed uart with autobaud, and an integrated dram controller. the isdn ta reference design illustrates how to use many of the integrated peripherals to provide a small, low-cost isdn ta. the reference design supports either an isdn 2b+d u or s/t network interface by a component population option. you can interface to a pc using either the high-speed uart connection at up to 230 kbit/s, or by using a full-speed usb connection at 12 mbit/s. note that the isdn data rate is 128 kbit/s, so the reference design?s uart transceiver is only 230 kbit/s. this limits the high-speed uart, which is actually capable of 460 kbit/s. the pcs that the isdn ta would connect are also a limiting factor because most are only capable of speeds up to 115 kbit/s or 230 kbit/s. about.book page ix wednesday, november 3, 1999 1:56 pm

am186?cc microcontroller isdn ta reference design manual xii isdn background isdn (integrated services digital network) is an alternative to analog phone lines. isdn provides greater performance than analog and is still affordable to consumers. there are many different variations of isdn available, but the most common variation is 128-kbit/s data transfer rate over two b (bearer) channels, plus 16 kbit/s of signaling data over the d channel; this is the 2b+d configuration, the configuration used by the isdn ta reference design discussed in this manual. another configuration uses a single b channel and transfers data at 64 kbit/s. broadband isdn is available and can achieve data rates in the 100-mbit/s range. there are a number of reference points in an isdn system. figure 0-2 shows a graphical representation of the isdn reference points. for more information about figure 0-2, refer to digital telephony, second edition , isbn 0-471-62056-4. the u reference point is the local loop between the le (local exchange) and the nt (network termination) device. the u interface is a two-wire interface, which in north america and asia is typically supplied by a telecommunications service provider. the u interface operates in 2b1q (two binary, one quaternary) format, and can travel for miles without repeaters. the t reference point is used only with customer premises switching equipment (nt2). the s/t reference point is the four- wire interface between the network termination device (nt1) and the terminal equipment (te1) or terminal adapter (ta). the s/t interface is offered in europe, and is also used with stand-alone nt1 devices. figure 0-2. isdn reference point diagram te1 te2 te1 nt2 ta n t 1 nt1 nt1 t r s u about.book page xii wednesday, november 3, 1999 1:56 pm
