[USR-TC] SNMP MIB Question

Does anyone know if I can use SNMP to change the service status of an individual timeslot on a PRI span on a HiperDSP to a soft busy state (or RESTORE the timeslot to IN SERVICE, if needed)? If I can, what is the OID? My NMC is running 6.2.17. I am not really too familiar with SNMP. I walked the MIBs and can only find 1.3.6.1.4.1.429.1.1.2.1.1.5.1014 (for modem 14, card 1 for example). But it appears to be read-only. The description is uchasEntityOperStatus.xxxx. Thanks -- Scot
