Protection Circuitry
Longitudinal protection is required at both the HDSL Transceiver Unit – Central Office
(HTU-C) and HDSL Transceiver Unit – Remote (HTU-R) interfaces because of the ground
connection used with loop powering. Two P2300SC MC SIDACtor devices provide
overvoltage protection and two F1250T TeleLink fuses (one on Tip, one on Ring) provide
overcurrent protection. (Figure 3.10) For the transceiver side of the coupling transformer,
additional overvoltage protection is provided by the P0080SA SIDACtor device. The
longitudinal protection on the primary coil of the transformer is an additional design
consideration for prevention of EMI coupling and ground loop issues.
