Prosody X cPCI is a highly configurable IP media platform that combines support for rich media processing resources, VoIP telephony and optional E1/T1 digital network access functions. The cPCI variant complements the award winning product line of Prosody X offering higher density and enabling higher availability solutions. Bringing unrivalled industry benchmarks in scalability and low cost per channel, Prosody X cPCI is an ideal building block for advanced VoIP applications. The product leverages Aculab’s core expertise in combining complex technologies into a powerful and flexible proposition that assures developers a simple, clear migration path. Prosody X cPCI offers ‘mix and match’ modules to scale a wide range of applications including medium and very high densities suitable for large enterprise, public networks and telco grade environments.

Telco grade functionality
Prosody X cPCI meets the particular functionality demands of ISPs and voice carriers by providing the reliability, resilience and scalability necessary for these customers. The product provides hot swap and board protection mechanisms, and supports sophisticated redundancy management to allow the creation of applications with ‘five 9s’ availability (99.999%), independent of the final solution scale or channel count. Prosody X cPCI media processing resources can be shared between several high level applications, where one of them could be on the local host and others on remote machines.  In case of failure of the main high level application, the board control can be switched to a remote standby alternative, therefore, providing service continuity by implementation of either N+1 or 1+1 protection schemes.

Unrivalled density and feature set
The Prosody X media processing platform enables delivery of feature-rich solutions that address the demands of the IP communications era. The cPCI variant offers a comprehensive selection of firmware algorithms that can run independently on its DSPs as well as the option of adding a primary rate trunk module, ensuring a market leading position is maintained. Up to 8 DSPs can be selected to run the algorithms and with each DSP capable of supporting up to 150 channels, a total of 1200 channels per board is achievable. Key media processing resources include record and playback with a range of compressions, DTMF tone generation and detection, matrix conferencing, echo cancellation, fax processing and data transmission protocols. Each algorithm can be used separately or in combination to develop more sophisticated solutions, making Prosody X the clear choice for advanced speech processing development. Whether transported by IP or TDM, media is handled by the same DSPs, thus giving a truly flexible platform. Because Prosody X can perform all of these functions on a single board, stock holding and the maintenance cost of spares is greatly reduced.

IP-based architecture
At the heart of Prosody X is an Ethernet switch, which is complemented by the TDM matrix used by previous generations of Prosody. This change acknowledges and accommodates the relentless shift toward an IP-based communications transport infrastructure and the benefits this can bring. The on-board IP architecture enables Prosody X to be distributed amongst different chassis platforms offering resilience and scalability as well as helping future proof solutions as they move to IP. A dual redundant 1Gb Ethernet interface provides the external IP connection, while the host’s cPCI bus will view Prosody X as if it were a NIC. Support for SNMP is offered to help manage Prosody X with appropriate information usually provided via the API being made available via the MIB. Both Net-SNMP and Microsoft’s SNMP are offered to provide choice and the host-based solution allows one agent to report on multiple boards.

Impressive TDM options
It is widely recorded that the circuit switched network will continue to be a great workhorse for many years to come, with the transition to IP-based transport happening over a period of years. To complement this, Prosody X provides the option of E1/T1 trunk interfaces via daughter boards known as PMX or PMXC modules, to ensure traditional TDM connectivity using the worldwide protocol suite Aculab is renowned for. Protocols include ISDN, CAS and SS7 – Aculab’s SS7 protocol stack coverage provides signalling messages for MTP, ISUP, SCCP and TCAP procedures and is constantly being upgraded. Taking advantage of the latest telephony software features, each trunk’s configuration may be made individually allowing for different protocols on different trunks, which may be E1 or T1, set with different terminating impedances. This flexibility is unmatched and includes reconfigurations without the need to restart a system, bringing great value to solution providers. A choice of 8 or 16 E1/T1 trunks per module provides for up to 496 channels.
