Component Selection
The “SC MC” SIDACtor devices and F1250T TeleLink fuse were chosen because these
components meet GR 1089 surge immunity requirements without the use of additional
series resistance. An MC is chosen to reduce degradation of data rates. The P2600SC MC
voltage rating was selected to ensure coordination with MLT voltages that can approach
150 V rms. The voltage rating of the P0640SC MC was selected to ensure coordination with
varying signal voltages.
Pair Gain Circuit Protection
A digital pair gain system differs from an ISDN circuit in that ring detection, ring trip, ring
forward, and off-hook detection are carried within the 64 kbps bit stream for each channel
rather than using a separate D channel. The pair gain system also uses loop powering from
10 V up to 145 V with a typical maximum current of 75 mA. (Figure 3.13)
