3.6.2 Configuring Analogue Extension (FXS) ports
Field Content
Input gain Indicates how much, if any, gain adjustment should be performed
in the input direction. Values are in decibels.
Output gain Indicates how much, if any, gain adjustment should be performed
in the output direction. Values are in decibels.
Echo canceller The echo cancellation delay and algorithm to be employed on the
port. The delay up to which the echo canceler can compensate is
specified in milli-seconds. An optional non-linear processing
echo suppression algorithm (NLP) can also be employed during
echo cancellation. If you expect the devices connected to the port
to be in a noisy environment how-ever, you might prefer not to
enable NLP, as it might result in the near-end noise being cut off
when speech ceases. Some remote users may find this
uncomfortable. NLP is recommended for quiet local
environments. Please see section 3.6.8.1 for a detailed
discussion around echo cancellation.
Allow transfer If enabled, the phone using this port is allowed to transfer calls.
Immediate mode When enabled, ring tone is not provided when the phone goes off
hook and the Com.X is required to take immediate action, such
as dialing an emergency number. Please see section 3.12.11.7
for more detail on using FlexPath with his feature.
Fax channel Indicates that this port is to be used for fax. Enabling this setting
disables echo cancellation on the port. Please see section 3.6.8

3.6.3 Configuring BRI ports
Field Content
Link Type Indicates whether this device is part of a point-to-point (i.e. DIDs
may be issued by the telco) or point-to-multipoint (i.e. one or
more multi-subscriber numbers may be issued, or multiple BRI
devices share the BRI bus.) The link type needs to match the
mode of the service provided by the telco.
Act as NT When disabled, the device is an ISDN TE, connected to the telco
NT. When enabled, this port acts as though it is an ISDN NT
device. This is useful when the Comma device is placed between
the PBX and the telco NT, e.g. for least-cost routing and BRI
gateway routing.
Bus termination Comma BRI cards have terminating resistors on-board, removing
the need for external terminators. If this device should terminate
