all this meant that while enniskillen's numbers could be six digits long, kesh's and lisnaskea's (and those of other dependent exchanges) could only be five digits, due to the 9-digit limit of the length of a phone number at the time. this severely restricted capacity in these areas. as a result, at the big number change, all these dependent exchanges were migrated to different numbers than their parent exchanges; in this instance while enniskillen's 01365 (the 1 coming from phoneday) was migrated to 028 66, kesh went from 013656 to 028 686 and lisnaskea from 013657 to 028 677. this meant that kesh could expand into the rest of the 028 68xx range.
