SIMPLEX REPEAT COIL MOUNTING |
The Repeat Coil modules provide transformer isolation and impedance matching
for use on either 2-wire or 4-wire transmission facilities. The module provides two
independent repeat coils. The frequency response of the module is virtually flat
throughout the voice band, 300 to 4000Hz. Option switches on the module allow independent
selection of either 150, 600 or 1200-ohm impedance on the facility sides of each repeat coil.
The module mounts in one (1) position of a Type-10 Mounting Shelf. In relay rack applications,
up to twelve (12) modules may be mounted across a 19-inch rack using a Model 101012 Shelf. |

REPEAT COIL MOUNTING PANEL |
The panel mounts into 19" or 23" relay rack with a 5.25" profile.
12 Repeat Coil modules, Model 32008, insert into the panel and are removeable
for quick service. Input, output, and simplex leads are brought out through
the rear on 25-pair connectors. Connectors are grouped by function to
simplify wiring and to minimize intercircuit crosstalk coupling. |
