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 
. TYPE OF TRUNK (P2) Pl: 182 P4: 3 
. TRUNK GROUP NUMBER (P3)

. OPERATION MODE (P4) P3: 13

2. USE CMC-254 TO MODIFY TRUNK ROUTE TIMING SO THAT SBCS FLASH TIMING VALUE MATCHES HOST 
PABX:

. 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. 
. THREE TYPES OF TENANT TRUNK SHARING DESIGNATIONS ARE AVAILABLE: 
- OUTGOING/INCOMING TENANT (NO TRUNK SHARING WITH OTHER 
TENANTS) 
- OUTGOING ONLY TENANT (SHARING INCOMING TRUNKS WITH 
OTHER TENANTS) 
- INCOMING ONLY TENANT (SHARING OUTGOING TRUNKS WITH OTHER 
TENANTS) 
0 STATION MESSAGE DETAIL RECORDING (SMDR) OUTPUT CAN BE RECORDED BY 
TENANT NUMBERS. FIFTH TENANT IS INDICATED BY CORRESPONDING “BLANK” 
OUTPUT FOR TENANT NUMBER REFERENCE.
