Digital Centrex Set on Analog Centrex Line? Digital Centrex Set on Analog Centrex Line? Factotum247 (IS/IT--Management) (OP) 3 Mar 17 19:20 Can you use a digital Centrex desk set on an analog Centrex line at all? I've got conflicting reports on this. I'm not sure of the set models as I'm not on-site right now. Aastra's and Meridians though. RE: Digital Centrex Set on Analog Centrex Line? biv343 (Vendor) 3 Mar 17 19:45 A digital centrex set won't function on an analog centrex line, and vice versa. The Meridian M5000 series phones are digital centrex and will only work off a Nortel digital centrex system. The Aastra phones could be either analog or digital, depending on model number. RE: Digital Centrex Set on Analog Centrex Line? curlycord (Programmer) 3 Mar 17 19:53 Two types of Centrex lines Digital Centrex Lines - as Biv343 describes about the M series phones - only the carrier can program them, be careful as butt set or toners may disable the set from the C.O. Test with a phone at demarc, if does not work call the carrier. Analog Centrex Line - like normal Pots lines including rollovers (hunt or equivalent) but with some minimal Centrex features used on analog sets or with PBX's. ________________________________________ Add me to LinkedIN **New Allworx Forum** =----(((((((((()----= www.curlycord.com Toronto, CAN RE: Digital Centrex Set on Analog Centrex Line? Factotum247 (IS/IT--Management) (OP) 4 Mar 17 01:53 Makes sense. Confirms what I thought. That's why we have modems after all, right? Can't go digital to analog or vice-versa with out some sort of converter in between.
