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
lightning.
The housing may be mounted vertically on a pole,
pedestal, or against a wall in
a manhole. |
|
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.
621 Series T1 Apparatus Cases are available in two configurations,
vented 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.
- 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
severe vibration.
- 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.

AC 4306 Series Apparatus Cases
provide an economical means of placing Tl/ISDN span line mini-repeaters, or enhanced
electronics in double-width plug-ins, into the copper network. They provide protection from the environment for up to six
mini-repeaters, or up to three double-width circuit plug-ins with one additional fault
locate slot. The apparatus case is available fully-pressurized with air-core cable stubs,
or in a vented with encapsulant-filled cable stub configuration, to allow mounting in most
underground or above-ground installation sites.
|
|
A sturdy,
corrosion-resistant pole/wall mounting bracket is provided with every apparatus case. The
aluminum card nest has six slots, with three easy-to-remove dividers to convert the card
cage to accommodate three double width plug-ins. The card nest is hinged for access to the
card nest wiring for service, or installing the available surge arrestor assemblies.
Internal and external order wire attach points are standard in every case.
- White enamel, formed aluminum base and dome
- Corrosion-resistant mounting bracket
- Long service life, even in corrosive
environments
- Pressurized or vented cases
- Houses up to six Tl span line mini-repeaters
- Houses up to six single-width ISDN repeaters
or up to three double-width ISDN repeaters

to three double-width circuit plug-ins
- Uni-directional or bi-directional spans,
with ten different wiring options
- Totally-grounded system at installation site
