There are 3 items in the CHOICE (spc, range, and one) The first two are SEQUENCE, so an explicit tag is needed to aid the decoder. The third item is an IA5String. > ServiceProviderCodeList ::= SEQUENCE SIZE (1..3) OF IA5String > > TelephoneNumberRange ::= SEQUENCE { > start E164Number, > count INTEGER > } > > MH>>> What is the difference between: > Range = TelephoneNumber Range, where > Start is an E164Number, and > Count = 1 > and > One = E164Number? > Two alternate codes means more complex coding. The IA5String shows the stat of a block of phone numbers, and the count says the number of consecutive telephone numbers. It would be better to require count to be greater than 1. I suggest: count INTEGER (2..MAX) > E164Number ::= IA5String (SIZE (1..15)) (FROM ("0123456789#*")) > > MH>>> E164 numbers can be composed only of "0123456789", no? > So, the use of # and * are currently undefined in this ID. > I would assume that: > # would be an ending digit indicating the end of a shorter than 15 digit > number. > * would be an ending digit wild-card meaning any phone numbers with > preceding leading digits. > However, that would render the meaning of "One" ambiguous, and > That would provide another way to do Range, which may complicate code. > Also, what would it mean if the # or * appeared at the beginning or middle of > a digit string? The WG already had a discussion on the list about whether to include # and *. I believe this represents the outcome of that discussion. Russ
