2 GENERAL DESCRIPTION

2.01 Remote Administration and Maintenance
is accomplished with a remote terminal/modem
communicating over the public telephone net-
work via either an external modem (connected to
a dedicated CO line or a standard telephone
port) or a modem unit (IMDU) installed on a PIOU
or PIOUS PCB. See Figure 1.

MODEM
Instead of an IMDU-equipped PIOU or
PIOUS, an external modem
PIOU
connected to either a dedicated
or
CO line circuit or standard
PIOUS
telephone port can
be used for Remote Administration
and Maintenance.

2.02 If using an external modem, the modem may
be connected as detailed in the Installation Sec-
tion, 400-096-208.
2.03 Remote Administration and Maintenance calls
may connect to the IMDU automatically via pro-
grammable CO line ringing assignments (Pro-
gram 78), or manually via the standard call transfer
feature at intercom number 19. Automatic connec-
tion allows remote programming to be accom-
plished after business hours without on-site assis-
tance via night ringing assignments.
2.04 Remote Administration and Maintenance al-
lows the following functions to be accomplished
remotely:
MODEM
(300 or 1200 BPS)
CO LINE
CO LINE
Program Mode: Provides for complete program-
ming of all STRATA DK programs (including
speed dial adds/changes).
Test Mode: Provides for testing of STRATA DK
stations and CO lines.
Data Dump Mode: Provides a complete printout of
all or individual STRATA DK customer data base
programs, including speed dial numbers and
LCD messages.
Message Mode: Provides for sending, adding, or
changing digital and electronic telephone LCD
messages.
Speed Dial Mode: Allows station and system
speed dial numbers to be programmed remotely.
NOTE:
All the functions in the preceding paragraphs
are also available via a terminal connected
directly to the on-site PIOU(S) PCB or a termi-
nal with a modem connected to a PSTU port
(Paragraph 5).
2.05 There are two levels of Remote Administra-
tion and Maintenance.
Level 1: Allows access to all programs.
Level 2: Allows access to Programs 30 ~ 39 and
77 ~ 89, which pertain only to individual station
options such as button assignments, class of
service, etc.
2.06 Each Remote Administration and Mainte-
nance level has a different programmable pass-
word for customer data base protection. This al-
lows a customer to make certain station moves,
adds, and changes in Level 2; while protecting the
critical system assignments in Level 1 (refer to
Program 00).

3 HARDWARE REQUIREMENTS

3.01 The STRATA DK must be configured with
either an IMDU-equipped PIOU or PIOUS or an
external modem connected to a dedicated CO line
or standard telephone circuit.
