Section 2: Components DS1000/2000 Product Description
2-OPX Module (P/N 92177A)
The 2-OPX Module provides two 2500 type analog circuits for con-
necting single line sets, modems and fax machines. It is also a handy
way to connect Voice Mail ports in systems without separate ASTU
PCBs. (See page 13 for more on ASTU PCBs.) The 2-OPX Module is
a stand-alone unit with its own internal DTMF receivers, ring genera-
tor and power supply. Since the 2-OPX Module is a true OPX, it can
connect to telco OL13 B/C OPX circuits. Even though it provides 2
analog circuits, the 2-OPX Module connects to a single digital
(DSTU) port. The 2-OPX Module is wall-mountable using the provided wall mount brackets.
The number of 2-OPX Modules you can install may also be limited by the System Load Factor. See
DS2000 System Configuration on page 18 for more.
The 2-OPX Module in not available in DS1000.
Digital Door Box (P/N 80560) and Analog Door Box (P/N 92245)
The Door Box is a self-contained Intercom unit typically used to mon-
itor an entrance door. A visitor at the door can press the Door Box call
button (like a door bell). The Door Box then sends chime tones to all
extensions programmed to receive chimes. To answer the chime, the
called extension user just lifts the handset.This lets the extension user
talk to the visitor at the door. The Door Box is convenient to have at a
delivery entrance, for example. It is not necessary to have company
personnel monitor the door.
There are two types of Door Boxes: Analog Door Box P/N 92245 and Digital Door Box P/N 80560.
Both Door Boxes operate identically. There are, however, some differences:
●
The Digital Door Box connects to a digital station port. The number of Digital Door Boxes
you can install may be limited by the System Load Factor. See DS2000 System Load Factor
Calculations on page 19 and DS1000 System Load Factor Calculations on page 23 for more.
●
The Digital Door Box is available in Universal Slot (02.nn.nn) versions of DS2000 and all
versions of DS1000.
●
The Analog Door Box is only available in DS1000 (2 maximum). An Analog Door Box plugs
into one of the dedicated Door Box ports (DOOR1 or DOOR2).
●
The Analog Door Box can be mounted outside. The Digital Door Box is not intended for out-
door installations.
Any extension that receives Door Box alerts can also activate a control relay. If the relay is con-
nected to electric door strike circuits, an extension user can press FLASH or a soft key to remotely
lock and unlock the entrance door. There is a single relay in DS2000, located on the CPRU. There
are two relays in DS1000, one for each Analog Door Box. Digital Door Boxes in DS1000 do not
provide relay control.
