Configuring a BRI interface to supply line power

You can configure only network-side BRI interfaces to supply line power to the terminal equipment.
NOTE:
Only ISDN BRI interfaces on the BSV module can operate on the network side.
You can perform this task only when no call is present.
To enable remote powering on an ISDN BRI interface:
Step
1. Enter system view.
2. Enter ISDN BRI interface
view.
3. Configure the interface to
supply line power.

Configuring the sliding window size on an ISDN BRI interface

Q.921 sends frames in order of their sequence numbers and requires an acknowledgment of each
transmitted frame. To improve transmission efficiency, Q.921 does not wait for a transmitted frame to
be acknowledged before it sends the next frame. Instead, it uses a sliding window mechanism for
transmission.
The sliding window mechanism enables Q.921 to send multiple continuous frames without waiting
for the acknowledgment of the previous frame. The sliding window size sets the maximum number of
unacknowledged frames. You can tune the size depending on the link status to maximize the
throughput.
When sending a frame, Q.921 checks the number of unacknowledged frames. For example, V(A) is
the sequence number of the previous acknowledged frame, V(S) is the sequence number of the
frame to be sent, and k is the sliding window size. If V(A) + k = V(S), the system stops sending
frames.
To configure the sliding window size on an ISDN BRI interface:
Step
1. Enter system view.
2. Enter ISDN BRI interface
view.
3. Configure the sliding window
size.
