Abstract
A system for determining slot specific information in a base station includes a switch provided in connection with each circuit pack in slots of the base station. The switches are selectively operated to isolate a particular circuit pack to associate the information relating to that circuit pack in a specific slot in the base station.
Claims19
A method for identifying a circuit pack in a specific slot, where the circuit pack is connected to a single wire bus, the method comprising:
- sending a plurality of circuit pack addresses over the single wire bus;
- and
- identifying an address of the circuit pack in the specific slot based on the circuit pack in the specific slot being isolated and
- responses received over the single wire bus from other circuit packs connected to the single wire bus, the responses being in response to the plurality of circuit pack addresses sent over the single wire bus, wherein the identified address of the circuit pack is one of the sent plurality of circuit pack addresses for which an acknowledgement was not received.
A circuit pack isolation system, comprising:
- a single wire bus;
- a plurality of switches, each switch associated with a slot for a circuit pack, each switch for selectively connecting the circuit pack in the associated slot to the single wire bus;
- and
- a control circuit pack configured to send a plurality of circuit pack addresses and to send an enable signal to isolate a first circuit pack in the associated slot from the single wire bus and to identify the first circuit pack having one of the sent plurality of circuit pack addresses in the associated slot based on at least one response received over the single wire bus in response to the sent plurality of circuit pack addresses, wherein the isolated first circuit pack is identified as the circuit pack having the one of the plurality of circuit pack addresses for which an acknowledgement was not received at the control circuit pack in response to the sent plurality of addresses.
A method for identifying a circuit pack in a specific slot, where the circuit pack is connected to a single wire bus, the method comprising:
- sending a first set of circuit pack addresses over a single wire;
- receiving first responses to the first set of circuit pack addresses;
- determining a plurality of circuit packs inserted into a plurality of slots based on the first received responses;
- isolating one of the plurality of slots;
- sending a second set of circuit pack addresses over the single wire bus;
- receiving second responses to the second set of circuit pack address;
- and
- determining a specific circuit pack is in the isolated one of the plurality of slots based on the second responses.
