The router is equipped with an applicable BSV interface card.

Configuration procedure

To configure a BSV BRI interface:
Step
1. Enter system view.
2. Enter the specified BSV BRI
interface view.
3. Configure an interface
description.
4. Enable B channel loopback
detection.
5. Set the MTU of the BSV BRI
interface.
6. Set the interval for sending
keepalive packets.
7. Enable the interface to
generate linkUp/linkDown
traps upon link changes.
8. Restore the default
configuration of the BSV BRI

Configuring AMD

Answering machine detection (AMD) is used to detect if a human voice or an answering machine is
answering the call by using a statistic algorithm. AMD is mainly applied in the predictive dialing
system in call centers, as some services need to recognize who is answering the call: a human being,
an answering machine, a fax machine, or a Modem.
AMD uses the answering rhythm (voice duration and silent time) as the statistic algorithm. Generally,
if the speaker is a human voice, there is always a period of silence after a short greeting. If the
speaker is an answering machine, there is always a short silence after a comparatively long greeting.
