Card-Edge Connectors
Figure 3 on page 5
details the wiring specifications for both card-edge connectors.
Gas-Tube Protectors
The eight replaceable gas-tube protectors are equivalent to a TII 47BT and have a breakdown voltage ranging from
300 V to 500 V. The breakdown voltage is a function of voltage rise-time. The tubes can withstand at least
400 repetitions at 10/1000 rise-time with 500 Amp discharges.
Thermal Deployment Limits
The HRE-602 can be deployed in an ambient temperature up to +135 °F (+57.2 °C) without solar load when
housing one doubler. Reduce these limits by +10 °F (+12.2 °C) when housing two HDU-409 doublers.
These requirements comply with Bellcore standards, which require HDSL equipment placed in
outdoor cabinets to operate in a temperature of -40 °F (-40 °C) outside the housing without solar
load and +115 °F (+46.1 °C) with maximum solar load and maximum power dissipation.
Full solar load is equal to maximum sunlight exposure as defined in Bellcore's Technical
Advisory TR-TSY-000057.
