l SBCS CAN FUNCTION AS A STANDALONE COMMUNICATION SYSTEM OR AS A FRONT-END SYSTEM BEHIND 
OTHER SWITCHING EQUIPMENT, SUCH AS A PABX. 
. SOME SYSTEM PARAMETER VALUES MAY REQUIRE RESETTING TO ACCOMMODATE CONFIGURATIONS 
POSSIBLE WITH A FRONT-END ARRANGEMENT. 
REFER TO CMC-100 TO COORDINATE FEATURE ACCESS NUMBERING PLANS FOR BOTH SYSTEMS AND 
CMC-200 TO COORDINATE STATION NUMBERING PLANS. 
1. USE CMC-250 TO MODIFY TRUNK ASSIGNMENT DATA: 
. EQUIPMENT NUMBER (Pl) CMC = 250

. ALLOWS SBCS TO BE SHARED BY AS MANY AS FIVE TENANTS. TENANTS MAY USE 
OWN STATIONS AND/OR TRUNKS, BUT SHARE COMMON CONTROL LOGIC, POWER 
SUPPLY, ATTENDANT CONSOLE, AND SERVICE TRUNKS. 
. STATIONS AND TRUNKS (EXCEPT TIE TRUNKS) ARE ASSIGNED TO TENANT 
NUMBERS SO EACH TENANT CAN ACCESS OWN TRUNKS. TENANTS SHARE SAME 
FEATURE ACCESS CODE AND STATION NUMBERING PLAN.
