I just had my phone switched from an 'analog' (standard 2500 set) to a AT&T ten button 'digital' set on our System 85 to gain an additional two lines. In doing that, I lost the ability to use a modem on the line. Is there any way to use a standard telephone device (like a modem or answering machine) with this phone? It's got a second eight-pin RJ- jack on the back marked 'OTHER'... The identifiying numbers on the phone are: RF90IL-19, Z7403D01B and 845P11. Any source for a device to add a standard RJ-11 device to this phone would be appreciated. Thanks in advance! Jeff Wasilko, RIT Communications

No, there isn't any way to connect a modem, but there shouldn't be any need to. If you've got a digital station line from a System 85 PBX, replace your digital voice terminal with one that has a data and voice capability. It won't give you an RJ-11 jack; it will give you an RS-232 interface. You connect that to your data terminal equipment (or computer) and you get connectivity at speeds up to 9600 bps through the PBX to other digital terminals. If your PBX has a modem pool, it will also allow you to dial outbound calls, and will insert a modem from its pool if your call goes out to an analog data station.

Jeff, it is not possiable to add a modem to your new set. The "other" jack is for add on equipment such as a speaker phone (I have one of those sets in my office and I work on Sys 85). In order to use your digital phone line, you would need a data module on your set AND the other end!!! Then you would use Sys 85 to tranmit in its own language (digital) between the two.

I think you'll find that there is a work-around to this problem. One of the things that can be plugged into the "other" jack (at least on the analog sets) is a General Purpose Adapter. You can plug in a modem (certainly up to 2400 baud), a fax machine, any single line type device, into the GPA (it has a standard RJ-14 receptacle). The GPA has a three position switch on the front: Basic (grabs on outgoing line when the single line device goes off hook), Auto (in conjunction with programming, this sends ring voltage to the single line outlet and allows faxes, answering machines and modems to answer calls), and Join (interrupts an existing voice call and bridges the call to the single line outlet on the GPA). Thus you can have data connectivity thru the system 85 using a modem, but not directly from an RS-232 port on your PC. The system 85 treats the modem transmission just like a voice, converting it into it's own language for transmission through the system, and returning your voice or modem transmission to it's original form at the destination of the call (another telephone on the system, or a line port going out of the system). It is possible on the Merlin( the system 85's smaller half-brother) to set the phone up for simultaneous voice and data calls, establishing two talk paths to the phone. I forget off the top of my head if the 85 can do this as well. davep@u.washington.edu
