Prosody X PCI Express R1 Card – Installation Guide
TDM switching
2048 full duplex channel switching between the local resources and the H.100 bus.
Four configurable E1/T1 trunks.
Maximum 30 channels per E1 trunk operating with CCS or CAS protocols.
Maximum 31 channels per E1 trunk for bearer only connection.
Maximum 24 channels per T1 trunk operating with CAS protocols or bearer only
connection.
Maximum 23 channels per T1 trunk operating with CCS protocols.
256 channels per media DSP resource
512 channels (full duplex) to module based DSP resources for signalling support
Flexible local switching between any two resources, this includes signalling DSPs,
media DSPs, E1/T1 trunks and H.100 expansion bus channels.
TDM clock synchronisation
Any E1/T1 interface can provide the reference clock which is then used as the source
for all TDM interfaces.
The H.100 bus can be used in slave clocking configuration as the direct source for
remaining TDM interfaces.
The H.100 bus can be used in master clocking configuration with the either
CT_NETREF signal as the indirect source for remaining TDM interfaces.

The Prosody X PCI Express card takes its power from the host computer expansion
bus and has the following provisional power requirements:
14W max, including the signalling DSP module, with a supply ratio of:
+ 12V DC ± 5% @ 1.1A
+3.3V DC ± 5% @ <0.1A
+3.3Vaux DC ± 5% @ 0A
It is the user's responsibility to ensure that the host computer will be able to safely
supply the power required by the card in addition to any other auxiliary apparatus.
NOTE
To ensure adequate heat dissipation within an enclosed system, a chassis with
forced air cooling is recommended for all installations.
