Section 2 - Operating Modes
2.1 SG-DRL3-IP Standby Mode
After start-up the line card enters the Standby mode and monitors
the network connection and the CPM3. Depending on the system's
status, the following conditions will be displayed for each line card:
*
The number of flashes on the yellow LED indicates the following
errors:
2.2 CPM3 Error
If the SG-DRL3-IP cannot detect the CPM3 polling, the SG-DRL3-IP will
start buffering incoming calls. Up to 768 alarm messages for the
printer and computer will be retained in the SG-DRL3-IP event buffer.
When the event buffer is full, the line card will stop processing alarms
and the status LED will begin flashing. When the CPM3 error condi-
tion is corrected, the alarm messages in the event buffer will be
transmitted to the CPM3 with the corresponding time/date the
alarms have been received.
2.3 Fault Data Message
When this problem is encountered, the following information is
transmitted to the printer and the computer:
NOTE:
This output for account code 'AAAAAA' indicates that data
has been received, but is not valid (e.g.,The packet is encrypted and
the SG-DRL3-IP does not have the proper key) or the T-LINK trans-
mitter packet was rejected (NAK) four times by the receiver. Please
also refer to Option 45.
2.4 Ethernet Interface
The SG-DRL3-IP has an Ethernet interface which operates as a
10BaseT/100BaseT IEEE 802.3 compliant Ethernet port (half duplex
mode). This port is accessible via a standard RJ45 connector. A LINK
plus ACTIVITY LED is also present on the board for diagnostics and
troubleshooting. The IP address of the SG-DRL3-IP is programmable.
The ethernet port is used for system connections, including the
transmitter and console ports.
CAUTION:
The ethernet communication lines must be con-
nected first to an approved (acceptable to the local authorities)
type NID (Network Interface Device) before leaving the premises
(e.g., UL installations, UL60950 Listed NID).
2.5 ULAA Receiver Database
The receiver has the capability of monitoring T-LINK transmitters
that are setup as ULAA units. The receiver will automatically keep
track of new transmitters and indicate whenever a transmitter has
been lost. No option is required on the receiver since if no ULAA
heartbeat signals are received then the receiver will function nor-
mally. Refer to
Appendix C: SG-DRL3-IP Events
.
2.6 SG-DRL3-IP Debug Output
Connect the RJ45 end of the debug cable to the debug output jack
on the front of the line card. Connect the female DB9 connector to
the serial port of a computer (COM1 or COM2 port - usually DB9
male. Refer to the
System III Installation Manual
for details.
