Recommendation: When using  a lookahead  interflow, first test to see if the 
receiving office is open for business.

The scenario is a sending switch in Los Angeles, with office hours from 8:00 AM 
to 5:00PM (8:00-17:00) PST and the receiving switch is in New York, with office 
hours from 8:00 AM to 5:00PM EST (5:00-14:00 PST). There is a 3 hour difference 
between the two switches. 

The example in Figure M-12 routes calls to the New York switch. If there are no 
agents available at the Los Angeles switch. It is possible for calls to be 
interflowed during hours that the agents in New York are not available, thus doing 
unnecessary processing. 

The example in Figure M-13 tests first to see if the New York switch is open 
before requesting a queue to the New York switch, thus avoiding unnecessary 
processing.
