Trying to locate the manual for this unit. Converts 4-wire type 1 signaling from PBX to CAMA trunks for 911 PSAP calling.
Can find nothing on the internet other than used units for sale, no mention of manuals.
May have also been branded under the name Teltronics.
Amcom acquired the company in 2008. This is an older technology. This site is using Rolm 9751 tie trunks on TTI cards.
This link to ebay will show the unit I am talking about.
