4.6 SG-DRL5/DRL5E/DRL5-2L - Line card
The SG-System 5 supports a maximum of 24 line cards. The SG-DRL5 PSTN cards function as a Telco interface to remote transmitters. The line card
receives alarm events from the transmitter, decoding them before forwarding the signals to the SG-CPM5 for subsequent output to the printer and auto-
mation outputs. SG-DL5 line cards ordered for the SG-System 5 are pre-assembled with SG-DRL5-ADPT and cabling.
NOTE: In order to install the DRL5 PSTN line card, the SG-S5LFANTR fan tray must be removed and the SG-S5LBRKT line card
extractor bracket must be installed.
