Blocking CICs
You might need to block a CIC or a range of CICs on your Cisco PGW 2200 Softswitch. Blocking a
single CIC sends a BLA message to the destination SSP. Blocking a range of CICs sends a CGB message
to the destination SSP. The range option only can be used to block CICs within a given trunk (T1 or E1).
To block a single CIC, log in to the active Cisco PGW 2200 Softswitch, start an MML session, and enter
the blk-cic:sig_srv:CIC=number command:
Where:
• sig_srv—MML name of a signaling service that is associated with the CIC you want to block.
• number—Number of the CIC you want to block.
For example, to block CIC number 1, which is associated with a signaling service called ss7svc1, enter
the blk-cic:ss7svc1:cic=1 command:
To block a range of CICs, log in to your active Cisco PGW 2200 Softswitch, start an MML session, and
enter the blk-cic:sig_srv:CIC=number,RNG=range command:
Where:
• sig_srv—MML name of a signaling service that is associated with the CICs you want to block.
• number—Number of the first CIC in the range of CICs you want to block.
• range—Specifies the end of the range of CICs to block.
Note You can configure the Cisco PGW 2200 Softswitch software to issue individual or group supervision
messages for point codes that are associated with an ISUP signaling service. ISUP signaling services
issue group supervision messages by default. If you configure an ISUP signaling service to issue
individual supervision messages, use of the range option issues individual supervision messages for each
CIC in the range, instead a single group supervision message.
For example, to block CIC number 1 through 20, which are associated with a signaling service called
ss7svc1, enter the following command:
blk-cic:ss7svc:cic=1,rng=20
To verify that the CICs have been successfully blocked, retrieve the status of the affected CICs as
described in the “Verifying CIC States” section on page 3-15. When you want to return the CICs to
service, you must unblock the CICs as described in the “Unblocking CICs” section on page 6-139.
Retrieving the Administrative State
The administrative state refers to the state of CICs (on the Cisco PGW 2200 Softswitch) and spans bearer
channels (on the associated media gateway). There are three possible states: locked, unlocked, and
shutdown. Use the rtrv-admin-state MML command to determine the administrative state of several
objects in the Cisco SS7 solution environment, including the Cisco PGW 2200 Softswitch, an associated
MGCP media gateway, a trunk group, a signaling service, spans and bearer channels that are associated
with a signaling service (for non-ISUP trunks), and CICs associated with a signaling service (for ISPU
trunks).
When you retrieve the administrative state of an object that consists of groups of CICs or spans bearer
channels, you receive an inferred target state that is based on the following criteria:
