CAUTION
•
Install or remove modules from the shelf only when the power is off.
If you install a module in the shelf with the power on, the internal
circuitry may suffer damage and the product warranty will be void.
•
Remove and install circuit boards only in a static-safe environment
(use antistatic wrist straps, smocks, footwear, etc.).
•
Keep circuit boards in their antistatic bags when they are not in use.
•
Do not ship or store circuit boards near strong electrostatic, electromag-
netic, magnetic, or radioactive fields.

Page 2: Ordering Information
The optional 49210 subassembly provides an interface to two telephone lines; a primary and a backup. The 44210 is a plug-in module that fits into any 400-type or similiar equipment housing. The front panel has status-indicat- ing LEDs, normal-through and monitoring jacks, test points, level-setting potentiometers, and a subassembly cutout window. - Page 3 CIRCUIT DESCRIPTION . 1 - F , 44210/49210 UNCTIONAL CHEMATIC 44210/49210-0798 <90-00025>...
- Page 4 The microprocessor provides central processing power to coordi- nate virtually all on-board functions carried out by the 44210. When power is initially applied to the 44210, a watchdog IC resets the microprocessor and UART. The microprocessor must pulse the watch dog IC within 1.2 seconds, or the watchdog IC resets the microprocessor again.
- Page 5 MPI Inputs Six MPI inputs directly interface the microprocessor on the 44210 using edge connector pins. When an MPI input becomes active, the microprocessor's input goes to a low state, causing the microprocessor to perform a dial-out. One of the MPI inputs (pin 22) is TTL/CMOS-compatible and is activated by grounding (ground to 1.5 VDC) and inactive when left open (3.0 to 5.0...
- Page 6 2 is grounded (with input 1 open or high), the relay is ON and line 2 is connected to the 44210 modem. If both line- select inputs are open or at a high level, the relay remains in the state appropriate to the last selected line.

LEDs. Override Switch The switch overrides the relay and line selectors, connecting only the selected line to the 44210 modem. If the override switch is in the center (OFF) position, then line selection is done by the line selectors. APPLICATION INFORMATION... - Page 8 FUNCTION DB-9 PINS DB-25 PINS Auto-Answer Refer to Fig. 2. When a 44210 is configured in this mode, it acts as an auto-answer modem (not Hayes -compatible). It answers an incoming call and establishes communications only. There is no automatic call-out on alarm or password features. When it hangs up, it will send a garbage character to the device to which it is connected.
- Page 9 APPLICATION INFORMATION modem, it must hang up itself after sending "+++". This mode is usually used when a 44210 is tied to a MAP's or 46062 General Purpose Processor's (GPP) Printer Port. Option Strapping and Switch Settings The 44210 has straps to configure the RS-422 and RS-485 ports and the operation of RTS and DTR.

J5 of the 44210. Four screws must be removed prior to mounting the 49210 on connectors J4, J5, and J6. Refer to Fig. 4. After mounting the 49210 on the 44210 module, replace the same four screws to hold the subassembly securely in place. - Page 11 If the 44210 is used in Hayes-compatible mode, refer to Table B or the instruction manual of the communications software in use. Checkout of the 44210 is done by placing the 44210 in operation with one or more 44210s or similiar modems at the distant end that are known to be good.
