I have a 911 circuit that currently is DPO in the Central office, comes into a 1/0 DAC's, and is delivered to the customer off a DPT card. Due to some rearranges, we are going to remove the 1/0 DAC's, and replace it with two Channel Banks. My question is, what cards would I put into the CB's to move the circuit on? Currently DP0--T1--1/0DACS--T1--DPT--Customer. New DP0-T1--CB(XX)--wiring--CB(YY)--T1--DPT--Customer. What flavor cards will XX and YY be? Thanks!
In theory a DPO talks to a DPT and vise versa a DPT talks to a DPO. Electrically this is how it has to be a DPT provides 48V and the DPO terminates 48V. This being said XX would be a DPT and YY would be a DPO.
