$q\3ruw? 0xowl6huylfh $ffhvv 3urfhvvru 5/&609 100467e conexant 3 conexant proprietary information technical specifications general description the rl56csmv/6 provides the processing core for six channels of a central site remote access server supporting high speed t1/e1/pri digital lines. the oem adds two oscillators, sdram, and discrete components to complete the multi-service access processor system. the access processor includes a full-featured, self- contained data/fax/voice modem solution shown in figure 1. data modem handshake, fax modem protocol, voice codecs, and isdn data connection functions are supported and controlled through the at command set. digital data pump (ddp) the ddp is a +3.3v/+2.5v conexant data pump supporting pstn data/fax modem operation, isdn b channel call termination mode, and voice coding/decoding. the ddp executes internal code including downloadable modules from on-chip memory. digital data transfers serially between the t1/e1 framer device and the ddp at a data rate up to 8.192 mbps. the t1/e1 framing device provides a strobe signal and the ddp tsa logic detects where the data for the channel starts in the serial tdm data stream using a programmable counter. the ddp performs pcm -law or a-law conversion and synchronizes with an external network clock. arm microcontroller (mcu) the arm mcu performs the command processing and interfaces to the central site system controller via a 16-bit parallel host interface. two 64-word deep fifos are used for improved data throughput between the access processor and system controller. this single powerful risc processor controls six separate channels. a sdram loader is available to support download from the central site system controller on startup, if desired. access processor operation in data modem modes, each channel can independently connect to pstn data modems at rates up to 56 kbps or isdn terminal adapters at rates up to 64 kbps. a downloadable architecture allows for software download. for pstn modems, complete handshake and data rate negotiations are performed. by optimizing the modem configuration for line conditions, the ddp can connect at the highest data rate that the channel can support from 56 kbps to 300 bps with automatic fallback. automode operation in v.34 is provided in accordance with pn3320 and in v.32 bis in accordance with pn2330. all tone and pattern detection functions required by the applicable itu or bell standard are supported. asynchronous to synchronous conversion is supported inside the controller to ease ppp processing in pstn data mode. when the remote end is an isdn terminal adapter, the rl56csmv/6 provides hdlc control including hdlc flag generation/detection, bit stuffing/extraction, and crc generation/checking. v.120, v.110, and lap-b x.75 are also supported. v.120 is a standard for encapsulating asynchronous data communications traffic into isdn data streams. in fax modem mode, the rl56csmv/6 supports group 3 facsimile send and receive speeds of 33600, 31200, 28800, 26400, 24000, 21600, 19200, 16800, 14400, 12000, 9600, 7200, 4800, and 2400 bps. fax modem modes support t.30 and t.38 fax requirements. fax data transmission and reception performed by the access processor are controlled and monitored through the eia- 578 class 1 and class 2 command interface. both transmit and receive fax data are buffered within the access processor. in voice mode, the csmv/6 encodes pcm audio data from the line into real-time protocol (rtp) packets for the host, and decodes rtp packets from the host, to output pcm audio data to the line. in voice mode, dtmf digits can be detected and transmitted, and a voice activity detector can be enabled. access processor firmware access processor firmware performs processing of general modem control, command sets, error correction and data compression, fax class 1 and class 2, voice coding and decoding (optional), and central site system controller interface functions. the firmware is provided in object code form for executing from external sdram after download on startup using the rom-coded boot loader. equipment designers can add their own functions in firmware using commonly available development tools and the c programming language. hardware interface signals the rl56csmv/6 interface is illustrated in figure 2. the 371-pin bga package identifying pin locations for the rl56csmv/6 is shown in figure 3. the rl56csmv/6 pin signals in the 371-pin bga are listed by location in table 2 and by interface in table 3. the rl56csmv/6 application signals are listed by interface in table 4. additional information additional information is described in the rl56csmv/6 anyport multi-service access processor hardware interface description (order no. 100469, formerly 1192), the rl56ddp designers guide (doc. no. 1141), the csmv/6 anyport? multi-service access processor software interface description (doc. no. 100597, formerly 1148), and the command reference manual (doc. no. 100468, formerly 1195).
