-. 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: .

DESCRlPTlOii . 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. 2.197
