Added basic information on blocking.

New page

== To force a block on a SS7 CIC group: ==

'''Status -> SS7 Isup -> Click on the CIC group -> Desired group state [Blocked] -> Apply States '''

Tu put back in default mode: 

'''Status -> SS7 Isup -> Click on the CIC group -> Desired group state [default] -> Apply States ''' 

Note: "unblocked" mode will disregard phyical trunk condition 

This is a good way to test CIC alignment: All CIC groups are blocked, except the one which needs to be tested. With a COT test or a voice call, the CIC alignment can be verified.

== Two things can cause a locally blocked condition: ==

1) The physical trunk that carries the CICs is down. 

To verify which trunk this is, go to: '''Isup -> Isup_stack [edit] -> Isup Interface [edit]''' Verify the Line service attached to the CIC group then, go to the main status and check the trunk '''Status -> Tdm Lines -> Line Services'''

 2) The CIC group has been set to block. 

To verify: '''Status -> SS7 Isup -> Click on the CIC group -> Desired group state [default]'''
