There are a number of additional tones that are probably worth considering as part of the initial set of symbols. If you look at TIA/EIA-41-D and 3GPP2 A.S0014, you'll find quite a few tone designations that are used in other standards.
A.S0014 defines: 1. Normal Alerting 2. Inter-group Alerting 3. Special/Priority Alerting 4. Ping Ring (abbreviated alert) 5. Abbreviated intercept 6. Abbreviated reorder I think #1 and #4 are covered in the current document, but the others aren't clearly represented. If you throw in the TIA/EIA values, you also have things like: 1. Long (Normal) 2. Short-Short 3. Short-Short-Long 4. Short-Short2 5. Short-Long-Short 6. Short-Short-Short-Short 7. PBX Long (Normal) 8. PBX Short-Short 9. PBX Short-Short-Long 10. PBX Short-Long-Short 11. PBX Short-Short-Short-Short Additionally, A.S0014 allows indication of pitch (high, normal, low) as part of the ringtone designation. It would be nice if we could tack this pitch data on to the end of the existing tokens (e.g., "normal.short.low"). I note that this points to a combinatorial explosion of IANA values -- perhaps we need to re-think how we're representing the registry. /a _______________________________________________ BLISS mailing list [email protected] https://www.ietf.org/mailman/listinfo/bliss
