Regular Operations
CANT and skip percentages can be different depending on the type of traffic.
• Direct routed—This trunk group is the first choice in a list of routes in a priority sequence coming
from the adjacent signaling point.
• Alternate routed—This trunk group is an alternate route in a list of routes in priority sequence
coming from the adjacent signaling point.
Note The alternate routed control is available only on trunk groups (call control configurations).
The outgoing load congestion controls are configured in sets that are referred to as ACC response
categories (ACCRCs). The ACCRCs attach a label to a set of configuration data for each control that can
be reused. You can configure only one ACCRC per SS7 signaling path (signaling configurations) or
trunk group (call control configurations) that supports outgoing traffic. If you do not assign an ACCRC
to an SS7 signaling path or trunk group, the system performs the default ACC response procedures.
There is an ACCRC field for each control type combination of every ACL indication level. For example,
there are three alternate routed skip control fields for ACL 1, 2, and 3: acl1arskip, acl2arskip, and
acl3arskip). The Cisco PGW 2200 Softswitch comes configured with a default ACCRC, which cannot
be modified. The following list presents the field values for the default ACCRC:
• acl1drcant—50
• acl1drskip—20
• acl1arcant—50
• acl1arskip—20
• acl2drcant—90
• acl2drskip—20
• acl2arcant—90
• acl2arskip—20
• acl3drcant—100
• acl3drskip—0
• acl3arcant—100
• acl3arskip—0
When an adjacent signaling point sends an ACL indication, the Cisco PGW 2200 Softswitch enables the
actions that are defined in the ACCRC for a duration that is defined by the configurable ACL timer
ACLDur.
The following sections describe how to manage OCL:
