| Description | For a clause 9 (10Mb/s) repeater, this counter is incremented every time the repeater state machine enters the TRANSMIT COLLISION state from any state other than ONE PORT LEFT (Ref: Fig 9-2 [IEEE 802.3 Std]). For a clause 27 repeater, this counter is incremented every time the repeater core state diagram enters the Jam state as a result of Activity(ALL) > 1 (fig 27-2 [IEEE 802.3 Std]). The approximate minimum time for rollover of this counter is 16 hours in a 10Mb/s repeater and 1.6 hours in a 100Mb/s repeater. |
