TISP4xxxH3/M3BJ Series for LCAS Protection
APPLICATIONS INFORMATION
Introduction
These protector pairs have been designed to limit the peak voltages on the line terminals of ‘7581/7582/7583 LCAS (Line Card Access Switch)
parts. An LCAS may also be referred to as a Solid-State Relay, SSR, i.e. a replacement of the conventional electro-mechanical relay.
The ‘7581 LCAS has two solid-state switches which connect the telephone line to the line card SLIC (Subscriber Line Interface Circuit), Figure
12, SW1 and SW2. A further two solid-state switches connect the telephone ringing generator to the line, Figure 12, SW3 and SW4. Applied
5-volt logic signals control the condition of the switches to perform the functions of line disconnect, connection to the SLIC and application of
ringing. If excessive long-term overdissipation occurs, a thermal sensor activates thermal shutdown and opens the switches. The SLIC side of
switches SW1 and SW2 is limited in voltage by internal protectors Th3 and Th4. The line-side of the LCAS is voltage limited by the two TISP
parts.

Additional functions are provided by the ‘7582 (line test access) and the ‘7583 (test-in and test-out access). Up to three conventional electro-
mechanical relays may be replaced by the LCAS. The resulting size reduction can double the line density of a line card.
This document covers the types of overvoltage protection required by the ’7581 LCAS and how the TISP
part voltages are selected to
provide these requirements. The LCAS ’7582 and ’7583 are also covered as the additional switches used in these parts are similar to the
’7581.
