Routing
Multi-Link:
● Multi-Link: Specify whether channel bundling should be enabled on this PPP connection.
The following inputs can only be made when multi-link is activated:
– Channel Allocation Mode: Specify whether channel allocation should be static or dy-
namic for this PPP connection.
In the case of static channel allocation, the required number of channels is established
at the start of the connection (see General PPP Parameters: B Channels). If the re-
quired number of system-routed B Channels is not available (for example, because
seized by calls), only the maximum available number of B channels is established. B
channels that subsequently become free can no longer be added to this multi-link con-
nection. A completely new connection must be established for this.
In the case of dynamic channel allocation, additional B channels are established or al-
located B channels are cleared down depending on the bandwidth used. The maxi-
mum number of B channels required for this multi-link connection is set in the "B Chan-
nels" field under General PPP Parameters. As in the case of static multi-link, the
number of B channels available may also be less than required here. In contrast to
static multi-link, however, B channels that become free can be used for the multi-link
connection if the current bandwidth requirement is high enough. B channel establish-
ment and cleardown can be controlled by setting the upper and lower multi-link thresh-
old and the upper and lower multi-link time limit.
The number of B Channels currently seized can be checked under Device Statistics
(see Section 7.8.1, "Device Statistics").
– Segmentation: If you enable this option, IP packets are split into multiple fragments.
The fragments are transmitted over various B channels in a multi-link connection and
reassembled into the original IP packets on the receive side. The activation of segmen-
tation leads to shorter transmission times for IP packets and more consistent B chan-
nel utilization. Segmentation should be enabled for voice data transmission in multi-
link connections to reduce jitter and therefore improve voice quality.
– Upper Multi-Link Threshold (%): This value specifies the upper threshold above which
an extra B channel is added. The threshold is based on the calculated utilization of the
last B channel established. The permitted value range lies between 51% and 100%.
