Cisco PGW 2200 Softswitch Release 9.8 Operations, Maintenance, and Troubleshooting Guide

Chapter 3 Cisco PGW 2200 Softswitch Platform Operations
Regular Operations
The system returns a message like the following:
MGC-01 - Media Gateway Controller 2001-02-23 14:13:40
M RTRV
"session=accstuff:mclcallreject"
/* MCLNAME = mcl1
CALLREJECT = 25
*/
To retrieve the settings for every MCL on your system, log in to the active Cisco PGW 2200 Softswitch,
start an MML session, and enter the prov-rtrv:mclcallreject:“all” command.
The system responds with a listing of the call release settings for each MCL.
MGC-01 - Media Gateway Controller 2001-02-23 14:15:02
M RTRV
"session=accstuff:mclcallreject"
/*
Name CallReject
-------------------- ----------
mcl1 25
mcl2 50
mcl3 100

Managing Outgoing Load Control
Outgoing load control (OLC) regulates outgoing traffic to reduce congestion on other signaling points
that provide an ACL indication to the Cisco PGW 2200 Softswitch. Traffic might be rerouted or released
instead of being sent to congested signaling points.
There are two types of outgoing load congestion controls:
• Cancel-to (CANT)—Because of congestion, causes the rejection of a percentage of the traffic that
would have been routed to an SS7 signaling path (systems that are configured for signaling) or to a
trunk group (systems that are configured for call control).
Note A Cisco PGW 2200 Softswitch configured for signaling was formerly called the Cisco SC2200 Signaling
Controller. A Cisco PGW 2200 Softswitch configured for call control was formerly called the
Cisco VSC3000 Virtual Switch Controller. Some documentation for your telephony solution might use
these names.
• Skip—Causes a percentage of the traffic that is routed to a trunk group to overflow to alternate
routes. If an alternate route is not available, calls are rejected because of congestion.
Note Skip controls are available only on trunk groups (systems that are configured for call control).
When applying congestion controls, the CANT control is given precedence over the skip control.
Percentages that are assigned to CANT and skip for each ACL are independent. If both skip and CANT
percentages are specified for a trunk group, these percentages are applied independently, based on the
number of calls that are offered to a trunk group. The results are given in Table 3-16.
