Hello friends, I would like to know if anyone knows this type of equipment that I believe is a distributor or digital telephone splitter, or telephone exchange, in short I can't find info and a friend brought it to me because it doesn't turn on, but I also don't know where to feed it. or with what tensions it works. What I did find were short antistatic diodes.

Hello friends, if someone has a data, however minimal it is, it is good. I ask the moderator if he thinks it is convenient that this question goes in another area of the forum so let me know so I post the question where appropriate.

It is a Harris DCA 780-805 Model Telephone DCA modem. It is Passive. Receive your food from the telephone line itself. and connects to the PC with the Parallel port It was usually used for internal telephone networks using PBX. I'm not sure but it could serve as a 56k modem for Dial Up. Or PC Telephone Dialer It's really weird. There isn't even information about what DCA means. clearly According to Wikipedia, DCA routing is used to assign channels on cell phones right now https://en.wikipedia.org/wiki/Channel_allocation_schemes There is not much use to give them. These devices were used with the old MS-DOS as a modem for local telephone interconnection (I doubt that the PC still has that port even to connect it if it works)

Hello charlie ramirez thank you very much for the clarification, I will try to feed it from the wired phone line to see if it lights any LED because the only thing I found was two short diodes but as I say I do not know anything about this device, I consult you know If this device has a program because they offered me one that guarantees me that it works and I saw it and it is the same, but the issue is if they have configured a program per user that is different or they are all the same and I can replace directly. Thank you very much for now, then I will qualify.

I found this page in Russian but it explains a bit its mode of operation http://ats-harris.narod.ru/H6_438.htm (Putting it in the translator is readable)
Basically it is a Modem Router for Internal Network (Create your own LAN) through twisted pair telephone cables It is based on NetBios protocol so it supports the Sharing of Printers
It has its own 128KB RAM included
You could try to make it work using MS-DOS. However, I think Microsoft Xenix Software is required
