is a highly configurable card that combines
support for rich media processing resources, IP telephony and optional
E1/T1 digital network access functions. Unrivalled benchmarks in density
and price will pave the way to a new era in communications building block
technology. 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 offers ‘mix
and match’ modules to scale a wide range of applications including
low and high densities suitable for enterprise and public networks.
The Prosody X media processing resource card 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 our customers’ market
leading position is maintained. Up to 4 DSPs can be selected to run
the algorithms and with each DSP capable of supporting up to 150 channels,
a total of 600 channels per card 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. In addition, Aculab’s host based
speech technologies ASR, TTS and SVI are also available under a cost
free licence from software downloads for use with Prosody cards.
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 card, stock holding is greatly reduced.

At the heart of Prosody X is an Ethernet switch in addition to the
TDM matrix used by previous generations of Prosody. This change
acknowledges and accommodates for 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 distributable amongst different chassis platforms offering
resilience and scalability as well as helping future proof solutions
as they move to IP. A dual redundant 10/100 BASE-T Ethernet interface
provides the external IP connection, while the host’s PCI
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 cards.
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 cards 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 version 6 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 4 or 8 E1/T1 trunks per module provides for up to
246 channels.
