Xorcom has designed a hardware echo canceller (HWEC) module for
its award-winning Astribank telephony interfaces and Asterisk-based
IP-PBX appliances. The module provides a high level of echo
cancellation and voice enhancement while reducing load on the CPU,
as compared to OSLEC, the software-based echo cancellation solution
provided in the standard Asterisk framework.

By reducing the load on the servers CPU, the number of
simultaneous calls that are supported on the telephony system is
increased significantly. The echo tail size of the hardware echo
cancellation module has been set to 128 taps, and load tests show
that the same number of simultaneous calls are achieved as when the
software echo cancellation is disabled completely.

Each separate device (Astribank / XR2000 / XR3000 / XE2000 /
XE3000) requires a single Echo Canceller card. The hardware echo
canceller option includes 32 voice channels and support for up to a
total of 144 channels. All ports/channels in the chassis need to be
licensed for the module to function. Additional channels are
licensed in bundles based on the telephony interface type:

Additional PRI Port (P/N LC0020): License(s) necessary
for 2nd, 3rd, 4th activated PRI port(s) in the chassis

Additional FXS Module (P/N LC0021): License support
additional FXS module(s) in PRI or BRI configuration. Note:
Hardware Echo Cancellation cannot be applied to FXO modules in a
single chassis configuration including a PRI or BRI module. In this
case, the FXO module should be installed in a separate (Astribank)

Additional BRI Channels (P/N LC0022): License(s)
support(s) up to 16 voice channels, in two channel bundles

*The echo cancellation hardware is an integral part of the
Astribank devices with 6 or more PRI ports and does not need to be
ordered separately.
