Cisco router and Meridian c11 T1 link

[WCHPikus]

Hello!
Could someone explain me, how th configure C11 for this?
Link T1 - 12 chanels only

how have do work?
Cisco router => Pbx
This is depend of dialing plan, but i thing the dialig plan will be from 3 to 4 digits eg, 100-499 or 2000- 4999.
router sending 3 or 4 digits, in unknown/unknow ISDN plan.
Router could be master or slave clock. (master on the first step)
PBX => router
Router expect 5, 4, or 3 digits, depend of dialing destination number
eg.
01-xxx where 01 country prefix, xxx, internal number
02-xxx
04-xx
05-xxx
...
question:
How to make routing, dial plan to t1 card?
In the best way, user have to dial prefix to T1 card, eg."78" and dial destination number.
Better will be if user could dial only destination number, PBX must be add or repeat country prefix.
eg user => "01 333" where 01-prefix to T1, PBX adding 01 and sending to router "01333".
