STATION ACCESS MODULE (SAM)
MODEL TLN3221B
1 .. DESCRIPTION
The Station Access Module (SAM) is standard equipment
in an
MSF 5000
or
MSF
10000 Data Station. It is also
available with the Smart Wildcard Option (X233) or with
the
MSF 50001 MSF
10000 Diagnostics Option (X34). The
SAM consists of a microprocessor and associated circuit-
ry, and occupies a single slot in the expansion tray. When
operating in a data station or in a diagnostic station, it
monitors the operational state of the station. It interprets
information from various sources within the radio, and
if
a problem is detected, provides an alarm indication to the
outside world.
The SAM card incorporates all functions of the previous
Repeater Access Controller (RAC) and has replaced the
C932 option with option X233. Configured
as
a software
programmable wildcard the SAM provides
24
outputs and
16 inputs along with RS232, tone (SelectS and Single-
'Ibne),
MDC1200,
and dual tone multi-frequency
(D'IMF) signaling capabilities. An additional relay out-
put board is available (Option
0175)
which provides eight
relay outputs
as
well
as
a ''breadboard" area for
special
applications.
2. APPLICATION INFORMATION
2.1 DATA
When used in conjunction with the MSF Data Station,
the SAM provides the interface between the BSC and the
station. It provides control inputs to the station from the
BSC and Alarm/Status Outputs from the station
to
the
outside world. The SAM has the capability of identifying
failed Field Replaceable Units (or FRUs)
via
alarms. Pre-
defined setup
keys
are available on the RSS screens to
conftgure all 1/0s for operation with the BSC.
The following is the complete list of the Diagnostic
Alarms which SAM is capable of reporting when used
with a data station or a standard MSF station with the full
diagnostics option (X34).
