OK, here's the deal.
You're telling me you have 2 sets of lines.
I will assume NOTHING, but tell you how I would do it if this was my switch.
You are already using the 70 pool for OUTGOING.
Hopefully, that is not also your INCOMING POOL.
If it is, we will need to talk. (or at least look at the rest of this info....)
HOWEVER, you said you ALSO have another set of lines.
I WOULD DO THIS:
Assign the "other" lines to the 890 Pool, and set ARS up to use the 890 Pool as one of your choices for outbound routing.
sys prog> tables> ars> sub a pools (for DAY TIME) sub b pools (for night time)....
NOW, here's where you gotta figure out how you want to change these things.
ROUTE 17 is the DEFAULT TOLL, choice 1 here is the FIRST pool you select, and, of course, choice 2 is the 2nd pool.
So, which pool is NORMALLY used for INCOMMING CALLS, make that choice 2, and the other pool choice 1.
Do the SAME THING for route 18, DEFAULT LOCAL (WHAT YOU GO TO IF YOU ARE NOT DIALING A 1 or 0)
Also, print out the ARS and see if there are any special considerations for any other routes.
ARS was developed to help you do LEAST COST ROUTING, that is, if it's cheaper to call Dallas over your 891 MCI lines, then route 214 to the 891 pool, if it's cheaper to call Ft. Worth over your SPRINT 892 pool, then route 817 over the 892 pool. With a little imagination, you can make ARS do many things for you....
But alas, most vendors any more charge the same no matter where you call. So that's kinda' a wash.....
Lot's o' luck.....
