Off-Hook (SLIC) Protection
Off-hook protection is accomplished by choosing a SIDACtor device that meets the
following criteria to ensure proper coordination between the supply voltage (V
maximum voltage rating of the SLIC to be protected.
This criterion can be accomplished in a variety of different ways. For applications using an
external ring generator and a fixed battery voltage, two P0641S_ SIDACtor devices
(P0721S_, P0901S_, or P1101S_ depending on the value of V
Ground, one Ring to Ground. For applications using a ring-generating SLIC such as AMD’s
Am79R79, the B1XX0C_ or B1XX1U_ can be used.

Reference Diagrams
Figure 3.21 shows the use of Teccor’s “SC” rated SIDACtor devices and the F1250T
TeleLink fuse to meet the surge immunity requirements of GR 1089. Teccor’s P1200SC and
P2000SC, specifically designed to protect Agere Systems (formerly Lucent
Microelectronics) Line Card Access Switch (LCAS), provide on-hook protection. Two
P0641SCs provide off-hook protection. Any additional series resistance is absent because
the “C” series SIDACtor device and F1250T TeleLink fuse are designed to withstand
GR 1089 surges without the aid of additional components such as line feed resistors and
PTCs.
