T-1/E-1 Circuit Protection
T-1/E-1 networks offer data rates up to 1.544 Mbps (2.058 for E-1) on a four wire
system. Signal levels on the TX pair are typically between 2.4V and 3.6V while the RX
pair could go as high as 12V. Loop powering is typically +/-130V at 60mA, although
some systems can go as high as 150V.
Protection Circuitry
In Figure 3-17, longitudinal protection is required at the Central Office Terminal (COT)
interface because of the ground connection used with loop powering. This is
accomplished using two P1800SC SIDACtor
s for over voltage protection and two
F1250T TeleLink fuses (one on TIP, one on RING) for over current protection. For the
transceiver side of the coupling transformer, additional over voltage protection is
shown using the P0300SA SIDACtor. For the regenerator where an earth ground
connection is not utilized, only metallic protection is required. Metallic protection is
satisfied using a single P0640SC SIDACtor across TIP and RING and a single F1250T
TeleLink on either Tip or Ring.
Component Selection
The
SC
SIDACtor and F1250T TeleLink were chosen because these components
meet GR 1089 surge immunity requirements without the use of additional series
resistance. The voltage rating of the P1800SC was selected to ensure loop powering
up to 150V. The voltage rating of the P0640SC was selected to ensure coordination
with varying voltage signals.
