Shahsad,

To meet the TELCO`s standarts from the line perspective is piece of cake indeed. Even the simplest form of circuit (as I described earlier) can easily meets the specs with some minor modifications. But the the problem is how you are going to convince the TELCO authorities. If you are not going to a commertial production in a volume, it is not worthwhile to take such a challange. Believe me.

As far as I understand that you are planning an alarm system;Just a last point of mine: another important criteria for such a rig is the drawn current; it should not exceed 10mA in searching state. 10 days battery endurance is a must.

Good luck.
