Thismeans that Lines 2, 3 and 4 do not haveto share the same telephone numbers forevery station. Any station can have itsown private line(s) or, the line(s) can beshared between some of the phones.Groups can be set up in programming toallow transferring, conferencing and LineStatus indications to work on sharedlines. By default, Line 2 belongs to Group2, Line 3 to Group 3 and Line 4 to Group4.For example, if telephone number 555-3333 is used on Line 3 on stations 11and 12 and 555-4444 is used on Line 3on stations 13 and 14, the Line Groupshould be changed from 2 to 5 on sta-tions 13 and 14. When this is done andstation 11 is off-hook on Line 3, station12 will show Line 3 is in use, but stations13 and 14 will not. Station 11 can trans-fer the Line 3 call to station 12 (which isin the same group), but cannot to sta-tions 13 and 14 (because they are in adifferent group). |
