621 Series T1 Apparatus Cases -
||621 Series Apparatus Cases provide
weatherproof mounting facilities for 12, 25 or 50 T1
miniature line repeaters. The housing consists of a molded-plastic
card cage, a molded-fiberglass baseplate, and a stainless steel
cover that maintains pressure-tight integrity. The non-metallic baseplate
improves corrosion resistance and isolates electrical surges due to
The housing may be mounted vertically on a pole,
pedestal, or against a wall in
Each housing is equipped with a
mechanism that allows the internal card cage to tilt
approximately 45 degrees. This provides clearance and
increases access to the rear of the card cage for test connection to
cable pairs and insertion/ removal of gas tube protectors
when the housing is mounted in an area with limited
overhead access. The baseplate may be rotated on the
mounting bracket in 90-degree increments, allowing three different
orientations of the card cage.
with encapsulant-filled stubs for above-ground
installation or pressurized with air-core stubs for
manhole installations. Several optional wiring configurations
and cable stub arrangements may be user-specified.
621 Series T1 Apparatus Cases are available in two configurations,
- Stainless steel cover
is durable and corrosion resistant.
- A stainless steel V-band assembly firmly clamps the
case cover to the baseplate O-ring seal. No tool
is required for removal.
- The latch assembly uses a T-handle on the tightening
nut, and is not affected by ice. Tabs on the
latch permit padlocking for security.
- Wire-wrap pins interface between plug-in units
inserted at the front of the card cage and
lightning protection kits installed at the rear.
- Retainer brackets prevent plug-in units from
disconnecting when the housing is subjected to
- Two cable stubs are secured in the housing baseplate
through cable strain relief grips that screw
onto the end of the hollow conical chambers extending
through the housing baseplate, providing an airtight entrance seal.
- Underside of baseplate includes an external Schrader
valve (to allow housing to be easily pressurized
and depressurized) or external vent (for vented units) and ground lug.
