provides a guideline for wire-wrapping the HMS-358 List 5 and List 6 chassis to support wire-wrapped
DSX-1 applications. The wire-wrapping option shown in
is for use with four-wire 3192 line units in
Central Office (CO) systems.
Group 1 (Port 1) connections typically provide a four-wire connection to the field and can be made through P11
(TX) and P12 (RX) or through wire-wrap connections under the field access cover (
). Group 2 (Port 2)
connections can be accessed through four wire-wrap posts under the field access cover.
