ORDERING INFORMATION
GENERAL DESCRIPTION
This shelf is designed to be a 4-wire analog or digital order wire assembly (OW). It is wired for:
♦44022-00 (A17-44022-00) Subscriber Line Interface module
♦44118-00 (A17-44118-00) 4W/4W VF Bridge
♦46105-00 (A17-46105-00) Dual VF 64 Kb Channel module.
The 05776 is equipped to use a 4-wire telephone such as the
A23-00010-20 or an A18-05775-00 3 channel OW speaker moni-
tor panel. No DTMF decoding is provided for this unit. DTMF
signaling is only used to get access to the VNET interface to the
PBX.
The unit is designed as a party-line system so that a caller, on
the OW channel, will simply speak into the handset and call who
he wants to talk to. The same is true from a call coming in from
the Off-Net package. The Off-Net unit associated with this
system will be the VNET PBX assembly A18-05774.
The 05776 operates from -21 to -56 volts with levels of +7 to
-16 dBm on any port of the 44118 VF bridge. In this application
all ports of the bridge will be set for -16 dBm on the transmit
ports and +7 dBm on the receive ports. The OW interface will be
made up of:
♦A 46105-00 Dual VF card in slot 1 (J1)
♦A 4118-00 4w/4w bridge in slot 2 (J2)
♦A 44022-00 subscriber line interface in slot 3 (J3).
NOTE:
With the release of the
B18-05776-XX Universal Order-
wire assembly, the A80-00630-00
M lead interface module has
been added.
This assembly will allow for con-
trol of M lead devices that re-
quire RS-232 or RS-449 RTS
leads to enable the 64 kb chan-
nels. The interface module can be
provisioned so that the on-hook
idle condition is normal low or
normal high.

21. Remove the termination from the dB meter and verify a level of 0
dB at the front panel blue XMT LVL test points for both channels 1
and 2.
22. Terminate the meter with 600 ohms and verify a level of +7 dB at
the front panel RCV DROP jack of channel 1.
23. With the meter still terminated, verify the level at the front panel
RCV DROP jack of channel 2 is -40 dB or more negative.
24. Move the signal generator to C2 pins 20 and 45.
25. Move the level meter to C2 pins 19 and 45
26. Verify a level of +7 dBm
27. Remove the signal generator and dB meter.
28. Using connector C2 connect the A18-05776-XX assembly to two
B11-46105-00 systems that are in the working in the terminal
mode. One will be connected to channel 1 and the other to
channel 2.
29. On the C2 connector of the A18-05776-00 that is used to connect
to the terminal mode 46105 modules, jumper pins 12 to 37 and
11 to 36.
30. Talk through the system in both directions and verify the module
works properly.
31. Verify that the green LEDs on the front panel light steadily for the
channel(s) that you are using. When a light is on, it means the
framing bit is being detected by the digital section of that channel
of the module, indicating synchronization of data transmitted to it.
32. Operation of the 46105 module consists of talking through the sys-
tem in either direction. The front panel RCV SYNC LED for the
channel that you are using lights steadily if the data being received
is in synchronization with the transmitting unit.
33. If the module is working in the repeater mode and the synchroniza-
tion signal is lost in either direction, the unit automatically reverts
to the terminal mode, allowing continued communications in the
direction from which the synchronization is still being received.
When synchronization is re-established, repeater operation re-
sumes. Verify that that a loss of a terminal from one direction has
no effect on the opposite direction of the system.
34. With the Order Wires talking to one another, remove the handset
and hit the Touch Tone pad on the A18-05775-00 and verify that
the tones can be heard at the other OW sites.
35. Hang up the handset.
36. At the remote location, on the Channel 1 side of the 46105, remove
a handset and verify that C2 Pins 39 and 40 of the A18-05776-01
are closed.

37. Hang up the handset and Pins 39 and 40 should go open.
Use the other terminal 46105 and repeat the process for Channel 2
and check Pins 7 and 8.
38. End of 46105 Alignment Procedure.
ALIGNMENT PROCEDURES
OPERATION
Operation of the 05776 Universal Order Wire shelf, when used in conjunction with a 05775 Speaker Panel is simple
and straight-forward. Use the steps below.
1. An 05775 Speaker panel will connect to the 05776 Universal OW
assembly using an 8 conductor RJ 45 connector that has male
connectors on each end. The cable must be straight through with
no nulls in it. The connector will connect between RJ 1 of the OW
assemblies and RJ 1, RJ 2 or RJ 3 of the speaker/monitor panel.
2. Remove the handset with the appropriate button selected for the
OW that is going to be seized.
3. The LED on the associated button on the 05775 will light indicating
that the unit is seized.
4. If the OW unit is equipped with a 46105 module, the M lead will
turn on and the 46105 will be activated. The 46105 module will
convert the analog signal from the OW user to a 64Kb RS-422 syn-
chronous digital signal and convert a 64Kb digital signal back into
an analog VF signal for the OW.
5. When the handset is off hook, the local speaker for the associated
OW will turn off and you can call whoever you need to call. Addi-
tionally, DTMF tones can be sent to activate the VNET Off-Net
PBX interface.
6. When the bridge is used in the application, ports 1, 2, and 3 of the
bridge will transmit what the OW user is saying, or any DTMF
tones that are being sent.
7. When a remote OW user answers, he will pick up his handset and
conversation can take place over the handsets.
