One serial boot port provides a standard Serial Peripheral Interface (SPI) running at up to 5 MHz. One standard test access port provides support for JTAG IEEE 1149.1. One internal PLL provides core frequencies of up to 166 MHz.
Two line-side TDM ports provide glueless connection to offthe-shelf framers and MVIP switches. Two packet-side full-duplex SpiceBus ports, running at up to 50 MHz, provide efficient connection to the backplane. One SDRAM port provides a 32-bit-wide data path capable of running at 166 MHz.

Gateway xChange VoP software in conjunction with the CALISTO BCM1500 / 1510 enables the highest density processing of voice / fax / data over packet networks in the industry. xChange Services The Circuit Interface Service (PCM or AAL1) supports G.711 µ-law / A-law, hosts G.168 echo cancellation with 32 / 64 / 128 ms tail lengths, detects and generates idle patterns, initializes linear ingress and egress media buffers, stores ingress / egress history, provides loopback towards circuit or packet network, provides gain control on ingress / egress samples, and provides energy measurement of ingress media. The Call Discrimination Service (CDIS) hosts fax / modem / V.18 detection, allows detection events to be used by the supervisory service to reconfigure the channel, and runs in either the ingress or egress direction. The Tone Service (PTE) detects DTMF, MF, and PTP tones, and incorporates programmable tone generation in packet or TDM direction, with features to support special tones like calling cards. The Conferencing Service transmits samples to another channel, receives samples and sums with local data, and includes an aggregation channel to provide support for larger conferences.
The Packet Voice Service (PVE) incorporates an adaptable / configurable jitter buffer, vocoders, and VAD / CNG supports asymmetric encode / decode provides G.711, G.726, G.729A / B / E, G.728, G.723.1, AMR, and GSM / EFR algorithms, with 5-ms packetizations for G.711, G.726, and G.278 allows super-packetization of up to eight frames, reorders packets in the jitter buffer, provides jitter buffer statistics, includes a packet loss concealment algorithm, provides egress VAD for jitter buffer adaptation control (in the absence of arriving SIDS) and for noise level / spectrum matching supports voice band data mode, with clock drift compensation, for modem / fax pass-through. The Fax Relay Service accepts T.38 or AAL2 packet formats, supports V.21, V.27ter, V.29, V.17 and V.33 data algorithms, incorporates end-of-line spoofing for non-ECM calls and HDLC spoofing for V.21 and ECM calls and supports both T.32 Data Rate Management methods. The Supervisory Service intercepts and filters events generated by services, and provides a high-level control interface. The Packet Interface Service supports either RTP / UDP / IP or AAL1 / AAL2 packet encapsulation, converts from internal packet headers to protocol-specific headers, sends and receives data on the packet interface, provides support for loopback towards circuit or packet network.

CALISTO Host API
Transport Layer
CALISTO Host API The CALISTO Host API is a C-language, re-entrant library that lets multi-threaded applications control CALISTO and SpiceBridge devices. The library is implemented in the ANSI standard C programming language, and is protected from the underlying operating system by an OS abstraction layer. The library can be ported between operating systems and host platforms. As a library, the CALISTO Host API always executes in task contexts provided by the application software. The CALISTO Host API allows users to embed CALISTO and SpiceBridge products into custom hardware architectures. The API provides C language software objects that correspond to the hardware components, and can be tied together to reflect the architecture of the custom system. The object-oriented design

provides the flexibility to add to and to expand the API as capability is added to CALISTO, or when new hardware devices become available. Users can place the library objects into tables maintained by call management applications, or add system-specific data to the objects so that they themselves become the table entries. The objects encapsulate addressing and state data to provide a flexible and scalable data organization. The object-oriented approach also lets the API manage state for related objects. If users reset a CALISTO, all Channel Socket Objects associated with the CALISTO change state as well. This encapsulation assists users in managing connections, and in implementing a hot backup redundancy scheme.
