HDSL Circuit Protection
High Bit Digital Subscriber Lines (HDSL) employ a digital line technology that utilizes a
1.544 Mbps (T-1 equivalent) transmission rate for distances up to 12,000 feet,
eliminating the need for repeaters. The signaling levels are a maximum of +/- 2.5V
while loop powering is typically under 190V.
Protection Circuitry
Longitudinal protection is required at both of the HTU-C and HTU-R interfaces
because of the ground connection used with loop powering. In Figure 3-10, this is
accomplished using two P2300SC 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 P0080SA SIDACtor.
Component Selection
The P2300SC SIDACtor and the F1250 TeleLink were chosen because both
components meet GR 1089 surge immunity requirements without the use of additional
series resistance. The P2300SC voltage rating was selected to ensure loop powering
up to 180V. For loop powering greater than 180V, the P2600SC should be considered.
The P0080SA SIDACtor was chosen to eliminate any sneak voltages that may appear
below the voltage rating of the P2300SC.
