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.
For more complete information on electrostatic discharge safety
precautions, refer to BellcoreTM Technical Reference #TR-NWT-000870.

OPTION NUMBER FEATURES
B18-04649-01 Wired shelf equipped with one (1) Tellabs 4003c and one (1) 44202 202-Type Modem
GENERAL DESCRIPTION
T
he B18-04649-02 shelf is a three-position shelf equipped with
two modules.
Slot 1 - Tellabs 4003C Line Amplifier
The Tellabs 4003C Line Amplifier with Loopback provides switch-
selectable level control, equalization, impendance matching in both
the transmit and receive channels of a 4-wire voice-frequency
transmission facility.
Additionally, the 4003C provides tone-activated or dc-activated
equal-level loopback of the facility.
Slot 2 - Dantel 44202 Compatible Modem
The 44202 module provides Bell-type 202 (4-wire) data communica-
tions between distant digital equipment locations. It also provides
on-board loop-back testing and multiple data interface inputs.
The 44202 is a plug-in P.C. board module that fits into any
400-type or similiar equipment housing. The front panel has:
♦Jacks.
♦LEDs.
♦Switches.
♦Test points.
♦Level setting potentiometers.
The are no options for the 44202 and it is not equipped to accept
subassemblies.

♦Alignment and Checkout Procedure
EQUIPMENT MOUNTING
Install the shelf in an equipment rack using the hardware pro-
vided. Refer to Fig. 1. Install the shelf as explained below.
Tools Required:
♦Phillips screwdriver
♦3/8 hex nut driver
1. Check the mounting brackets.
The brackets are installed at the factory so the front of the shelf
extends forward from the equipment rack. You can remove the
brackets and reinstall them for flush mounting. To install the
shelf in a 23-inch rack, remove the brackets and install the
optional mounting brackets that are in a parts bag attached to the
unit.
2. Install the shelf.
Install the shelf in the equipment rack, using the hardware
supplied in the parts bag. Refer to Fig. 1 in conjunction with the
following steps.
1. Facing the frame rail, place the shelf in the rack. Secure the shelf
with three Phillips-head screws and lock washers - two on the right
side at the top and bottom, and one on the lower left side.
2. Install one ESD stud with lock washer in the upper left location.
3. Secure all fasteners tightly, ensuring proper grounding between the
ESD stud and the frame rail.
4. Place an ESD label next to the ESD stud.
5. From the rear of the bay, install the other ESD stud into the frame
rail next to the shelf. Secure tightly, ensuring proper grounding be-
tween the ESD stud and the frame rail.
6. Place an ESD label next to the ESD stud.

ALIGNMENT AND CHECKOUT PROCEDURE
All options and level settings are factory-set as shown in Fig. 2.
Verify switch and strap options are set as shown in Tables A
through E. The following procedure should be used for verification
of level settings or if the Engineered Data levels require changes.
Level changes should only be required on the XMT or RCV pad on
the front panel of the 4003C Line Amplifier. Level settings between
the Line Amplifier and the 44202 Modem are factory-set for proper
loopback.
Refer to Fig. 6.
1. Action: Configure the Tellabs 4003C and the Dantel 44202 modules
as shown in Tables A through E.
2. Action: Ensure that power is removed from the equipment shelf.
Terminate or open the transmit path to the existing data circuit.
Install the modules in the proper slots.
CONTINUED . . .

04649-1098<90-00194> PAGE 9
3. Action: Apply power to the shelf.
4. Action: Connect a Transmit Measuring Set (TMS) to the XMT
LINE jack of the 44202 modem. Configure the TMS for 600 ohm ter-
minated measurement.
5. Action: Place the TEST switch, on the 44202 modem, in the ON
(up) position.
Result: The RTS and DTR LEDs light. A 1200 Hz tone is trans-
mitted to the test set.
NOTE: Failure to achieve the desired result indicates lack of power or a
defective module.
6. Action: Adjust the XMT LEVEL potentiometer to obtain a reading
of -6 dBm. (Turn clockwise to raise the level; counterclockwise to
lower the level.)
NOTE: If the transmit level cannot be reached, place the XMT GAIN
jumper on the 44202 to HIGH. If the level still cannot be
reached, the module is defective and should be replaced.
7. Action: Move the TMS cable to the 4003C XMT OUT jack.
8. Action: Adjust the 4003C XMT pad switches (located on the front
panel) to obtain the engineered data level.
9. Action: Connect the TMS send jack to the 4003C RCV IN jack. Set
the TMS to send the engineered data level (13 db below tone level).
10. Action: Connect the TMS rcv jack to the 4003C RCV OUT jack.
11. Action: Adjust the 4003C RCV pad switches (located on the front
panel) to obtain a reading of -15 dBm on the TMS.
12. Action: Connect the TMS (set for bridging reading) or db meter to
the test points labeled RCV and GND.
Result: The CD LED lights.
13. Action: Adjust the RCV GAIN pot to achieve a -20 dBm reading in
the TMS.
NOTE: If the receive gain cannot be adjusted, the module is defective
and should be replaced.
14. Action: Disconnect the TMS and place the TEST switch in the OFF
(down) position.
15. This completes the DST alignment. Connect an RS-232 cable from
the GTP to C1 of the DST shelf and remove the termination or open
plug in the transmit path to the existing circuit.
