Number of assignment complete messages for all MS power classes in underlaid subcell, full-rate. Number of congestion at assignment or immediate assignment in underlaid subcell.
Number of released TCH signalling connections due to transcoder resource congestion during immediate assignment on TCH. TFNDROP is stepped at the same time.
Number of first assignment attempts on TCH for all MS power classes. Successful attempts are counted in the target cell and failed attempts are counted in the serving cell. The serving cell is the cell where the mobile station was tuned to an SDCCH or TCHAvailable Basic Physical Channels (BPCs) for traffic channels accumulator. Also available for overlaid subcell, TAVAACCSUB. Number of accumulations of available BPCs for traffic channels counter. Also available for overlaid subcell, TAVASCANSUB.

Total number of dropped TCH connection due to low signal strength on uplink in underlaid subcell i.e. below LOWSSUL.

Number of released connections on SDCCH due to TCH- or Transcoder (TRA) congestion in both underlaid and overlaid subcell.
Dropped SDCCH connection at bad quality down- or uplink per cell in underlaid subcell i.e. worse than BADQDL and/or BADQUL.Dropped SDCCH connection at low signal strength on down- or uplink in underlaid subcell i.e. below LOWSSDL and/or LOWSSUL.
Handover attempt made to better K-cell (only for the Ericsson 1 locating algorithm), I.e. Signal Strength.
Number of handover attempts due to bad downlink quality. There is one HO counter for bad uplink quality called HOUPLQA and one for excessive timing advance called HOEXCTA.
Number of handover attempts due to excessive timing advance called HOEXCTA.

Number of intra cell handover attempts (decisions) at bad quality on both links.
The counter (TOTPAG) counts the total number of PAGING messages received from the MSCThe counter (TOTCONGPAG) counts the number of discarded PAGING messages due to lack of capacity in the BSC or due to congestion in the BSC paging queues or due to no Data Link Individual is available for a paging request taken from the paging queue.

There is also a counter for all accepted random accesses (CNROCNT) that means all except failed random accesses. The counters RAANPAG and CNROCNT are also incremented for TRXT connections. The failed random access counter (RAACCFA) is incremented for a Random access received with too high TA, values that are not used or in case of 'software file congestion'. Answer to paging (RAANPAG). The counter will be stepped for cause value 100x xxxx.Call reestablishment (RACALRE). The counter will be stepped for cause value 110x xxxx, Call reestablishment, TCH/F is needed, or originating call and NECI bit not set to 1, or procedures that can be completed with an SDCCH and NECI bit not set to 1.Emergency call (RAEMCAL). The counter will be stepped for cause value 101x xxxx.Other service request (RAOSREQ). The counter will be stepped for cause value 111x xxxx, Originating call and TCH/F is needed, or originating call and the network does not set NECI bit to 1.All other cases (RAOTHER). The counter will be stepped for cause value 000x xxxx, Location updating (SDCCH needed).
