Updated: a) When a channel assignment to a super-reuse TRX in an IUO DR is started. b) When the direct access to a super-reuse TRX is started.

001165 / SUCCESS TCH SEIZURE FOR DIRECT ACCESS Counter ID: 001165 Network element name: SUCCESS TCH SEIZURE FOR DIRECT ACCESS Version: 3.0 NetAct name: TCH_SUCC_SEIZ_FOR_DIR_ACC Definition updated in release:S7 Description: Number of successful seizures for a TCH in direct accesses to a super-reuse TRX during the call setup phase. Counters 001009 and 001091 are updated along with this counter. Updated: When the RRM allocates a TCH as a response to a TCH request in a call attempt using direct access to a super-reuse TRX procedure. See figure Internal intra-cell direct access from a regular DCCH to the super-reuse TRX.

001099 / TCH SEIZ DUE SDCCH CON Counter ID: 001099 Version: 3.0 Network element name: TCH SEIZ DUE SDCCH CON NetAct name: TCH_SEIZ_DUE_SDCCH_CON Description: Number of successful TCH seizures because of congestion on the SDCCH. This counter is updated along with counter 001044. Updated: When the RRM allocates a TCH as a response to a request for SDCCH seizure during congestion on the SDCCHs. The RRM allocates a TCH if the TCH allocation (=FACCH setup) is allowed in the message carrying the request for the SDCCH seizure. See figure FACCH call setup due to SDCCH congestion with counters.

057032 / TCH RE EST ASSIGN Counter ID: 057032 Network element name: TCH RE EST ASSIGN Version: 3.1 NetAct name: TCH_RE_EST_ASSIGN Description: Number of the TCH re-establishment assignments. Updated: When an ASSIGNMENT_COMPLETE message is received on the TCH from the BTS in case of a call re-establishment. In case of a FACCH call set-up due to SDCCH congestion, this counter is updated, when the ESTABLISH_INDICATION message is received on the TCH from the BTS. This counter is also updated with S6 feature TCH Assignment to Super-reuse TRX in IUO (intra-cell/inter-cell directed retry) and with S7 feature Direct Access to Super-reuse TRX in IUO (intra-cell/inter-cell) in case of a re-establishment. This counter is not updated after an external handover nor in case of an external DR.
