To program setup information into the DSN-100, it will be necessary to make all cross connections and to program trunk translations in the PBX. See examples of PBX translations for analog interface.
After all other work is complete, plug in the power supply. Note! PBX ground must be connected to the common ground of the power supply. The amber led labeled "program" should blink if the unit is new. If it was previously programmed the green "idle" led will be blinking. In that case, momentarily push the recessed program switch labeled "pgrm mode". Before programming, it will be necessary to have the following information available:
Remove the FAC plug from the DSN-100. If the unit was wired to it's 56 pin connector, temporarily remove the "M" signaling wire (pin 40). From a touch tone phone, dial the trunk access code. After the unit answers, enter the following information in the exact order.
" # " ends the programming session. Example: 1, 1, 30, 4, 2006, # = Precedence in, precedence out, 30 second transfer, 4 digits in dial plan, 2006 call coverage number.
After all information has been entered and the trunk returned to idle, the "program" led will turn off and the "idle" led will blink.
Precedence calls normally come directly to voice terminals in the PBX rather than to attendant consoles. However, when an incoming call to a voice terminal cannot be connected within some preset period (30 seconds is a typical value), the call is routed to another voice terminal to be answered. The procedure for answering a precedence call at a console is the same as for any other type of call.
An attendant or a voice terminal user can place a precedence level call in accordance with local practices. To place a call, the user must dial the DSN trunk access code followed by the precedence level requested and the DSN phone number (7 to 10 digits). It is not necessary to have a special 16 button dial to place precedence level calls. The precedence numbers and their corresponding levels are as follows:
A user must dial a precedence level on all calls using a precedence trunk, even routine calls. The ability of PBX users to place calls can be controlled via class of service and trunk restriction.
A voice terminal user who gets busy tone after placing an outgoing precedence call should hang up, and then call the local attendant for assistance. The attendant may be able to place the call on a higher precedence level trunk than a voice terminal user can access. The attendant may also use voice pre-emption to request use of a trunk.
