1.
General
1.01 This practice describes the Remote Record Unit (ALD3), an electronic system
that interfaces with the 13Aand
14A
Announcement Systems. This compact unit
allows the userto add
or
change recorded messages
on
either announcement system
from a remote location.
It
should be noted that any reference made to the
13A
Announcement System within the contents of this practice, will also hold true
for
the
13A+Announcement system.
The
only exception is maximum message length which is
specified in Table
A.
1.02 This practice is reissued to update information
about
the
AL03
RRU to
correspond to its feature changes and enhancements.
The
specifiC reasons for
reissue are listed below:
(a) Modify Tables B, E, and I and add Tables A, F, and G to incorporate changed
features and functionality. Also modify paragraphs 8.01, 8.14, 8.16, 8.17, 9.03,
9.04, 10.01, 10.04, 10.06,
10.08,10.10
through 10.16, and Figures 5 and 6.
Delete paragraph 8.19. Add paragraphs 10.18 through 10.25.
(b) Modifyparagraph 2.07 to include new systems with which the
AL03
interfaces.
(c) Modify Figure 5
to
correspond tothe circuit pack changes.
(d)
Modify any references
to
the
•AL02
Diagnostic Request• to indicate simply
•oiagnostic
Requesr
since more than one type
of
14A
system
now
exists.
(e) Modify paragraphs 12.03through 12.05 to incorporate
new
troubleshooting
techniques. Add paragraphs 12.06through 12.12.
(f) Add Ftgures 1 and 3
to
illustrate the system architecture.
(g) Add Appendix A to Indicate securHy code Information.
1.03 This practice contains an admonishment.

• Single User
-limited
to Telco users
• Multiuser-
Telco and commercial users.
Single
User
2.12 The purpose of the single-user mode is to block all commercial useraccess. The
single
user
has access to all functions performecl
by
the ALD3. Position 2 of the
ALD3 DIP switch must
be
set to the OFF position
for
the single-user mode.
Multiuser
2.13 In the multiuser mode, the Telco user has access to all functions performed
by
the ALD3. The commercial usercan access only the record and playback
functions. Position 2 of the ALD3 DIP switch is set to the ON position
for
the multiuser
mode.

SecurityCodes
2.14 The user must have a security code in orderto access the ALD3.
See Part 13.
3. Function
3.01 The ALD3 Is an interface between a user on the switched network and an
announcement system channel (13A or 14A). The userenters function codes in
the form of Touch Tones to perform various announcement system functions.
3.02
The ALD3 communicates to the 14A Announcement System by a simple protocol
· of selecting the
channel, sending function codes on a data bus, and monitoring a
read acknowledge line to determine if the data was properly transmitted.
3.03
The AL03 communicates to the 13A Announcement System bybringing the
channel
access lead to ground for playback or record. When a recording is to be
made, a record request is sent to the 13A and the FML cut-through cycle is monitored.
M. the beginning of the FML cycle the recording will begin. Once the recording begins,
the record relay on the 13A is monitored until the recording cycle is completed.
3.04 Acomplete list
of functions available at the 940A connector forthe AL03 is given
In Table H. All wiring information for the ALD3 to the 13A or 14A Announcement
Systems should be referenced to SD-97811-01.

Power
Requirements
4.01 The power required for the RRU is
-48
V DC. The operating voltage limits are
-39.5 to -57.0 V DC and will not
be
damaged up
to
-60 V DC. The preferred
source
of
this powerisTALK battery,
but
SIGNAL battery power is acceptable
if
TALK
battery is not available In the frame in which the AAU is installed. The normal current
drain is 0.125 amperes perALD3. Power is protected
by
a separate 0.25Afuse for each
ALD3 in the frame distribution circuitry.
