CONNECTIONS
An H2TU-C module occupies one card slot in the respective Office Repeater Bay for which it is
named. Power and alarm signals are provided to the module through the backplane of the
shelf. DSX-1 and HDSL2 loop signals are connected to the wire-wrap pins or mass termi-
nation (amphenol) shelf connectors corresponding to the slot the module occupies.
