0181     found, the DetId and ApvPairs are updated. The number of APV pairs
0182     is checked.
0183     
0184     4) If the DCU is not found in the cached map, a "random" DetId is
0185     assigned (using the remaining "unassigned" DetIds within the
0186     cached map). The DetId is only assigned if the number of APV pairs
0187     is consistent with the entry in the cached map.
0188     
0189     5) If no appropriate match is found, the DetId is assigned a
0190     "dummy" value using an incremented counter (starting from 0xFFFF).

0192     6) All Dcu-DetId mappings are accumulated in a new map, and this

0279     FedChannel-Dcu-DetId mapping information.
0280     
0281     This method is typically used when the FED connections (ie,
0282     "module.xml" file) does not exist, such as prior to the FED
0283     cabling or "bare connection" procedure.
0284 
0285     The map is built using information cached by the SiStripConfigDb
0286     object, comprising: 1) the hardware device descriptions, as found
0287     in the "fec.xml" file; 2) and Dcu-DetId mapping, as found in the
0288     "dcuinfo.xml" file. If any information is missing, the method
0289     provides "dummy" values.
0290     
0291     Methodology:
0292 
0293     The FEC cabling object is built using the hardware device
0294     descriptions (ie, from "fec.xml"). 
0295 
0296     Given that the FED channel connections are not known, APV pairs
0297     are cabled to "random" FED ids and channels. FED ids are retrieved
0298     from any FED descriptions cached by the SiStripConfigDb object
0299     (ie, from "fed.xml"). A check is made to ensure sufficient FEDs
0300     exist to cable the entire control system. If not, the shortfall is
0301     met by generating FED ids using an incremented counter (starting
0302     from 50).
0303 
0304     If the DcuId (provided by the hardware device descriptions) is
0305     null, a dummy value is provided, based on the control key.
0306     
0307     The Dcu-DetId map (ie, from "dcuinfo.xml") is queried for a
0308     matching DcuId. If found, the DetId and ApvPairs are updated. If
0309     not, a "random" DetId within the Dcu-DetId map is assigned. Note
0310     that a check is made on the number of APV pairs before the DetId
0311     is assigned. If no appropriate match is found, the DetId is
0312     assigned a value using an incremented counter (starting from
0313     0xFFFF).
0314 
0315     All Dcu-DetId mappings are accumulated in a new map, and this
0316     modified map is returned by the method.

0638 /**
0639    Builds the SiStripFedCabling conditions object that is available
0640    via the EventSetup interface. The object contains the full
0641    FedChannel-Dcu-DetId mapping information.
0642     
0643    This method is typically used when only the Dcu-DetId map (ie,
0644    from "dcuinfo.xml") exists and the FED connections (ie,
0645    "module.xml" file) and device descriptions (ie, from "fec.xml")
0646    are both missing.
0647     
0648    The map is built using the Dcu-DetId map that is cached by the
0649    SiStripConfigDb object. As a minimum, the map should contain
0650    values within both the DetId and APpvPair fields, but if any
0651    information is missing, the method provides "dummy" values.
0652     
0653    Methodology:
0654 
0655    The FEC cabling object is built using the Dcu-DetId map (ie,
0656    from "dcuinfo.xml"). For each entry, the DcuId, DetId and ApvPairs
0657    values are retrieved. For each ApvPair, a FED channel connection
0658    object is created using "dummy" hardware addresses.
0659 
0660    If the DcuId (provided by the hardware device descriptions) is
0661    null, a dummy value is provided, based on the control key.
0662     
0663    If the DetId is null, a value is assigned using an incremented
0664    counter (starting from 0xFFFF). 
0665 
0666    If the number of APV pairs is null, a value of 2 or 3 is randomly
0667    assigned.
0668 
0669    Given that the FED channel connections are not known, APV pairs
0670    are cabled to "random" FED ids and channels. 
0671 
0672    All Dcu-DetId mappings are accumulated in a new map, and this
0673    modified map is returned by the method.
